==Columbia River and Old Oregon Trail Highways==

These two highways had continuous mileposts; the Old Oregon Trail based its mileposts off of where it branched from the Columbia River Highway.

Oregon Route 42N

2026-02-15T01:50:44Z

Jonathan: Replace 1955 state highway map with April 1955 map that shows OR-42N

{{Routebox|type=OR|number=42N|shield_variant=1948|name=Oregon Route 42N|highway=Coos Bay-Roseburg Highway #35|map=OR_42N-map.jpg|maintained_by=Oregon State Highway Department|length=≈3.77|created=1954|removed=1956?|start_terminus_dir=West|start_terminus={{Jct|type=OR|number=42|shield_variant=1948|page=Oregon Route 42|route=OR-42}} in Winston|end_terminus_dir=East|end_terminus={{Jct|type=US|number=99|shield_variant=1948|page=US Route 99|route=US-99}} in Shady|prev_route={{Jct|type=OR|number=42|page=Oregon Route 42|route=OR-42}}|next_route={{Jct|type=OR|number=42S|page=Oregon Route 42S|route=OR-42S|align=right}}}}
'''Oregon Route 42N''' was a primary state route assigned in 1954 between [[Oregon Route 42|OR-42]] in Winston and [[US Route 99|US-99]] in Shady, just south of Roseburg. Designated along what would become an easterly extension of the [[Coos Bay-Roseburg Highway #35]] along a former stretch of US-99/[[Pacific Highway #1]], it was removed from the system sometime between 1956 and 1958.

==History==

After World War II, Oregon began constructing its two primary US highways, US-99 and [[US Route 30|US-30]], on newer, faster and wider alignments. Many of these new stretches bypassed smaller towns and cities, including Roseburg, Winston and Dillard in Douglas County along US-99. Once these bypasses were constructed and US-99 was moved onto the new alignments of the Pacific Highway, the Oregon State Highway Commission decided to retain the older sections in the highway system, either by creating new secondary highways and routes or by extending primary highways and routes.

In April 1954, the OSHC formally announced its renumbering plans for a few such sections of former US-99 once the new highways opened to the public. Among other items, the Coos Bay-Roseburg Highway was extended northeasterly from its previous terminus in Winston to the new highway in Shady. Curiously, its associated route number, OR-42, was '''not''' extended along the same alignment; instead, it was routed southeasterly through Dillard to meet with the new US-99 at Booth Ranch, eventually extending along the [[Tiller-Trail Highway #230]] (replacing [[Oregon Route 227|OR-227]]) to the junction of [[Oregon Route 62|OR-62]] at Trail. This left the extension of the Coos Bay-Roseburg Highway without a route number, so the commission decided to assign it '''OR-42N'''<ref name="roseburgnr_1954-04-08">''Roseburg News-Review.'' "Reconstruction of Highway Through Oregon to Result in Route Number Changes," 8 April 1954, pp. 1-2</ref>:

<blockquote>
Highway reconstruction in Oregon will result in changes in route numbers, it is announced by the Oregon Highway Commission. As new highway sections are completed and put into use, new titles will be adopted. Changes will start during the summer.

Several Douglas County roads are affected. ... Another announced change brings the Tiller-Trail Cut-Off into the system as an extension of the Roseburg-Coos Bay Highway. The road from Winston to Coquille now is known as State Highway 42. This route is to be extended eastward over the old Pacific Highway from Winston through Myrtle Creek to Canyonville and east from Canyonville through Tiller to Trail. '''The section from Winston to Roseburg, following the present highway, which is to be bypassed, will be known as S.H. 42N.'''</blockquote>
<cite>- ''Roseburg News-Review'', "Reconstruction of Highway Through Oregon to Result in Route Number Changes," April 8, 1954</cite>

[[File:1955-04_RouteNumbersPrincipalHighways_Roseburg.png|300px|thumb|right|This April 1955 map segment shows OR-42N along a former portion of US-99 between Winston and Roseburg.]]
[[File:1956 OfficialMap Roseburg Inset.jpg|300px|thumb|right|This inset of Roseburg on the back of the official 1956 state highway map does not show the OR-42N junction or the OR-235 designation.]]
[[File:Cgperry OR 42N shield.jpg|200px|thumb|right|The wooden OR-42N shield found at a Salem, Oregon antique store in 2016 by AARoads user CGPerry.]]
The change to OR-42 can be seen in the 1955 official state highway map, but a shield for OR-42N is not shown due to the small amount of space available to place it. In addition, Roseburg didn't have a city inset on the state map until the following year, and the portion covered was too far north to see the junction where OR-42N terminated. However, OR-42N ''can'' be seen on an April 1955 map that shows the route numbers of Oregon's principal state highways. This map, reprinted in the 1956 Traffic Volume Tables, also shows OR-42's extension along the Tiller-Trail Highway.

Around 1956, the state highway commission decided to cosign a bunch of [[US Route 99 Business|US-99 Business]] routes south of Eugene along the former US-99 alignments that had received state route numbers in 1954. Roseburg was no different; [[US Route 99 Business (Roseburg)|its business route]] started to the north in Winchester, then travelled along [[Oregon Route 235|OR-235]] (another 1954 designation) through Roseburg, Shady (where OR-235 terminated), Winston and Dillard to end at Booth Ranch. Despite the new US-99 Business designations, most of the 1954 state route designations lasted until at least 1962. OR-42N is the exception on the shorter end; it may have been removed from the system around 1956 or 1957, the latter year being when the new US-99 section from Shady to Booth Ranch opened to traffic. It was left off a list of US and state route descriptions published in December 1958 — the route descriptions of OR-42<ref name="oshd_desc_1958-12_16">Oregon State Highway Department. "Description of US and ORE Numbered Highway Routes," December 1958, p. 16</ref> and the Roseburg US-99 Business<ref name="oshd_desc_1958-12_10">Oregon State Highway Department. "Description of US and ORE Numbered Highway Routes," December 1958, p. 10</ref> would have listed OR-42N at intersections or along cosigned portions ('''bolded''' below), but neither do:

{{RouteDesc|quote=ORE42 –

More research is needed to build a more accurate timeline of this route.

===Rediscovery===

Long forgotten after its brief lifespan in the 1950s, OR-42N was rediscovered on the AARoads roadgeek forum on September 30, 2016 after user CGPerry posted a photo of a wooden OR-42N shield he purchased at an antiques store in Salem<ref name="aaroads_2016-09-30">Perry, Curtis Gregory [CGPerry]. ''Oregon 42N'', AARoads, 30 September 2016, https://www.aaroads.com/forum/index.php?topic=18931.0, last accessed 5 February 2021</ref>. The shield looks a little weathered but appeared in good shape, suggesting that OR-42N was indeed signed along that stretch of the Coos Bay-Roseburg Highway.

'''Welcome to Beaver State Roads!'''

My name is Jonathan. Simply put, Beaver State Roads aims to be your one-stop shop for information on Oregon state routes, highways, and other important roads. It was borne out of an earlier project, [http://oroads.beaverstateroads.org ORoads], which was originally hosted on Angelfire starting around 2002 under my pseudonym ''Jason of ORoads''. Unfortunately, ORoads became all but abandonned in the late 2000s-early 2010s due to life and other things, and during that time both the site design and the information within grew stale. Beaver State Roads strives to correct the outdated information plus add in the wealth of additional knowledge obtained over the past 20 years, presenting route and highway history and data as accurate as possible.

== 📄 Pages ==
While I'll be adding more pages to the site in the future, here's what's available now:

* Pages on Oregon state routes:
** [[Oregon Route 2]] 🚧, what is now US-26 from Cannon Beach Junction to Portland
** [[Oregon Route 37]], created in 1972
** [[Oregon Route 42N]], rediscovered thanks to [https://www.aaroads.com/forum/index.php?topic=18931.0 a 2016 AARoads post]
** [[Oregon Route 64]] — yes, you read that right — an extremely short-lived state route which became a westward extension of Oregon Route 140
** [[Oregon Route 127]], applied to Cornelius Pass Road between Burlington and Hillsboro in 2020
** [[Oregon Route 132]], applied to the Delta Highway within Eugene in 2019
** The second (and current) iteration of [[Oregon Route 224]] 🚧, created c.1961
** The first iteration of [[Oregon Route 231 (Oswego-Wilsonville)|Oregon Route 231]] from Oswego to Wilsonville, which may have only existed on paper around 1934
** [[US Route 320]], proposed to — and soundly rejected by — AASHO in 1958, rediscovered thanks to [https://groups.google.com/g/misc.transport.road/c/xaZ3k8VXwRI#ae67e67c372e78a3 a 2005 misc.transport.road post]
** [[US Route 730]] 🚧, currently both America's highest-numbered and shortest-length US route, defined in 1926
* Articles on mileposting and related signage:
** [[Mileposts]]
*** A [[List of Surviving Concrete Mileposts|list of surviving concrete mileposts]] originally erected starting in 1924
** [[Bridge and Culvert Inventory Markers]]
** The [[Mile 69 Problem|"Mile 69 Problem"]]
* A page of [[Common Abbreviations|common abbreviations]] used on the site

Future articles will revolve around [[Oregon Route 6]] and [[Mileposting in Oregon|Oregon's mileposting system as a whole]].

== ❓ How to Help ==

At present, writing these articles is a solo effort. Once I get some good information on here in the near future, the goal is to recruit additional Oregon roadgeeks as contributors. The decision to present this site in a wiki format was made with collaboration and education in mind. I don't have all the answers, and want to give people who may have those answers a platform on which to reveal them. Once I figure out some basic guidelines, I will extend offers as necessary.

However, there are other ways to help:

* What I prize above all is '''information'''. This includes (but isn't limited to) any documents, photos, maps, articles, meeting minutes, or other miscellany that may shed new light on Oregon's highways or provide a glimpse into the past, present or future. If you have anything about Oregon's highways that I can use on this site — especially historic or unique photos — please feel free to send it to '''beaverstateroads''' ''AT'' '''gmail''' ''DOT'' '''com'''. You will be given credit on the [[Beaver_State_Roads:About|about page]] once I write it.
* That said, I will eventually figure out how to set up accounts for people to '''donate''' to assist the site. This is necessary because unfortunately, a lot of good information, including high-quality photos, are locked away behind expensive fees to retrieve and scan the data. For example, the Oregon Secretary of State's office demands $20 per high-quality scan of photos, and research time in the Multnomah County archives can add up quickly. Any future financial assistance I receive would be much appreciated, and I would make an effort to document where and how the money I receive is used.
* I may also need some assistance making this site '''mobile-friendly''' in the near future.

Jonathan: Update recent news

[[File:2020-04-12 i5-nb-exit-286-night 6958.jpg|350px|thumb|right]]
'''Welcome to Beaver State Roads!'''

My name is Jonathan. Simply put, Beaver State Roads aims to be your one-stop shop for information on Oregon state routes, highways, and other important roads. It was borne out of an earlier project, [http://oroads.beaverstateroads.org ORoads], which was originally hosted on Angelfire starting around 2002 under my pseudonym ''Jason of ORoads''. Unfortunately, ORoads became all but abandonned in the late 2000s-early 2010s due to life and other things, and during that time both the site design and the information within grew stale. Beaver State Roads strives to correct the outdated information plus add in the wealth of additional knowledge obtained over the past 20 years, presenting route and highway history and data as accurate as possible.

== 📄 Pages ==
While I'll be adding more pages to the site in the future, here's what's available now:

* Pages on Oregon state routes:
** [[Oregon Route 2]] 🚧, what is now US-26 from Cannon Beach Junction to Portland
** [[Oregon Route 37]], created in 1972
** [[Oregon Route 42N]], rediscovered thanks to [https://www.aaroads.com/forum/index.php?topic=18931.0 a 2016 AARoads post]
** [[Oregon Route 64]] — yes, you read that right — an extremely short-lived state route which became a westward extension of Oregon Route 140
** [[Oregon Route 127]], applied to Cornelius Pass Road between Burlington and Hillsboro in 2020
** [[Oregon Route 132]], applied to the Delta Highway within Eugene in 2019
** The second (and current) iteration of [[Oregon Route 224]] 🚧, created c.1961
** The first iteration of [[Oregon Route 231 (Oswego-Wilsonville)|Oregon Route 231]] from Oswego to Wilsonville, which may have only existed on paper around 1934
** [[US Route 320]], proposed to — and soundly rejected by — AASHO in 1958, rediscovered thanks to [https://groups.google.com/g/misc.transport.road/c/xaZ3k8VXwRI#ae67e67c372e78a3 a 2005 misc.transport.road post]
** [[US Route 730]] 🚧, currently both America's highest-numbered and shortest-length US route, defined in 1926
* Articles on mileposting and related signage:
** [[Mileposts]]
*** A [[List of Surviving Concrete Mileposts|list of surviving concrete mileposts]] originally erected starting in 1924
** [[Bridge and Culvert Inventory Markers]]
** The [[Mile 69 Problem|"Mile 69 Problem"]]
* A page of [[Common Abbreviations|common abbreviations]] used on the site

Future articles will revolve around [[Oregon Route 6]] and [[Mileposting in Oregon|Oregon's mileposting system as a whole]].

== ❓ How to Help ==

At present, writing these articles is a solo effort. Once I get some good information on here in the near future, the goal is to recruit additional Oregon roadgeeks as contributors. The decision to present this site in a wiki format was made with collaboration and education in mind. I don't have all the answers, and want to give people who may have those answers a platform on which to reveal them. Once I figure out some basic guidelines, I will extend offers as necessary.

However, there are other ways to help:

* What I prize above all is '''information'''. This includes (but isn't limited to) any documents, photos, maps, articles, meeting minutes, or other miscellany that may shed new light on Oregon's highways or provide a glimpse into the past, present or future. If you have anything about Oregon's highways that I can use on this site — especially historic or unique photos — please feel free to send it to '''beaverstateroads''' ''AT'' '''gmail''' ''DOT'' '''com'''. You will be given credit on the [[Beaver_State_Roads:About|about page]] once I write it.
* That said, I will eventually figure out how to set up accounts for people to '''donate''' to assist the site. This is necessary because unfortunately, a lot of good information, including high-quality photos, are locked away behind expensive fees to retrieve and scan the data. For example, the Oregon Secretary of State's office demands $20 per high-quality scan of photos, and research time in the Multnomah County archives can add up quickly. Any future financial assistance I receive would be much appreciated, and I would make an effort to document where and how the money I receive is used.
* I may also need some assistance making this site '''mobile-friendly''' in the near future.

Creating the most complete history of Oregon state highways is a herculean effort, but with your help it doesn't have to be. Thank you in advance!

: The Oregon Department Of Transportation owns and maintains about 8,000 miles of state highways. One small section of that 8,000 miles is unique. And it’s located in the High Desert. Oregon Highway 27 starts as Main Street in Prineville. On its entire 44.78-mile southbound route, there is only one sign telling you that you’re driving OR 27.

As part of its “I-205 Improvements Project,” the agency’s solution is to add a third lane in each direction on I-205 between Stafford Road and OR 99E, as well as a northbound entrance-to-exit lane (or “auxiliary lane”) between OR 99E and OR 213.

Bridge and Culvert Inventory Markers

2026-01-09T21:40:17Z

Jonathan: Added Lincoln County bridge inventory marker section

'''Bridge and Culvert Inventory Markers''' are signs that identify bridges and culverts for jurisdictional maintenance purposes and occasionally to assist the travelling public. Oregon has placed inventory markers on bridges since around the year 2000, but some counties and cities have used them in decades prior.

== State Highways ==
[[File:Odot-bridge-inventory-marker-examples.png|258px|thumb]]
=== Bridge Inventory Markers ===

By 2001, ODOT started placing standardized inventory markers at some bridges and overpasses. ODOT's logo is at the top, with a phone number underneath it. Information about the bridge — route number, highway number, milepoint, and ODOT bridge number — is placed in the middle, with the name of the feature being crossed below that. Variations do exist, likely as a result of the contractors used on various projects:

* The "ODOT" in the ODOT logo used to be in Helvetica, but has changed typeface in recent years. All other text is in FHWA Series B, though often times it is condensed even more to fit additional information.
* Phone numbers change depending on the location of the marker and are included as a public safety service. Numbers currently documented include:
** 503-378-2299: 24/7 ODOT Dispatch Center
** 503-283-5859: ODOT Region 1 (Portland Metro Area) Dispatch Center
** 503-362-0457: ODOT Region 2 (NW Oregon) Dispatch Center
** 541-296-2215: ODOT Maintenance District 9 (The Dalles)
* Phone numbers sometimes have dashes in between them.
* Some markers display the text "EMERGENCY ONLY" below the phone number in Series D.
* Interstate routes are displayed with an "I-" in front of the number; by comparison, US and state routes are usually not prefixed by "US" or "OR".
* Milepoints are usually to two decimal points, though some markers exist with only a single decimal point.
* All letters on the markers used to be in all caps; however, the intersecting feature text can sometimes be found in mixed case, such as in markers along the [[Oregon Route 18|Newberg-Dundee Bypass]].
* The text in the intersecting feature section is usually centered, but can sometimes also be left-aligned.
* Milepoints can be negative. If this is the case, they will be displayed with a minus sign in front of the milepoint (e.g. MP -0.52). Negative mileage used to be known as "X-mileage", though there are no known inventory markers that use an "X" instead of a "-".

While many of ODOT's inventory markers legibly display correct information, quite a few do not:

* Some markers place the highway number in the "RTE" section and vice versa – for example, the marker at Mills Bridge on [[Oregon Route 6|OR-6]] displays Route 37 and Highway #6
* Some markers display the wrong route number – for example, the marker on [[Oregon Route 202|OR-202]] across Beneke Creek erroneously displays [[Oregon Route 47|OR-47]] in the "RTE" section
* Some markers on unsigned or formerly-unsigned state routes place the route number in the "RTE" section, but place a condensed abbreviation of the highway name in "HWY" – for example, markers on [[Oregon Route 103|OR-103]] display "Fishhawk F" in illegibly-small condensed Type B
* Some markers display a non-existent route – for example, markers on [[Oregon Route 194|OR-194]] erroneously state they are on "US-51"
* Some markers display redundant information – for example, some markers on OR-18 display the highway number and/or milepoint inside the intersecting feature section in addition to their usual spots

=== Culvert and Stormwater Facility Markers ===

Around 2013, ODOT started placing standardized markers at culverts and stormwater facilities. For culverts, two types of markers are defined in [https://www.oregon.gov/odot/engineering/202207/RD398.pdf ODOT Standard Drawing RD398], aptly named Type 1 and Type 2.

* '''Type 1''' markers are 4″ × 6–12″ strips of green thermoplastic tape affixed to the road, with no other information added.
* '''Type 2''' markers are 3½″ × 13¼″ white panels with a green stripe at the top. "ODOT" appears above the stripe. A number appears below the stripe — either the Drainage Facility ID (or "DFI number") if the culvert span is less than 6 feet, or the Bridge Structure ID if the culvert span is between 6 and 20 feet. Below the number is the culvert milepoint. All text on the marker is FHWA Series C, called "Type C font" in the drawing.

Stormwater facilities have three types of markers defined in [https://www.oregon.gov/odot/engineering/202207/RD399.pdf ODOT Standard Drawing RD399], named Type S1, S2 and S3.

* '''Type S1''' markers are flexible plastic posts embedded into the ground in two colors, red and green. Red posts signify the start of a stormwater facility maintenance area, and green posts signify the end of the maintenance area. Dimensions are the same as [https://www.oregon.gov/odot/engineering/202207/TM570.pdf ODOT TM570 Type 2 flexible plastic posts], but these omit the 4″ reflective sheeting bands. No other information is added to these posts.
* '''Type S2''' markers are the same size as the Type 2 culvert markers above, and have a similar design. A Type S2's top color band is blue instead of green, and the milepoint is replaced by a 5″ × ¼″ black stripe which can be optionally turned into an arrow to indicate the direction or location of the stormwater facility. Otherwise, both Type 2 and Type S2 display the same information.
* '''Type S3''' markers are essentially DFI numbers stamped onto access covers like manholes and vaults to identify underground stormwater facilities. For durability, ink is not used.

ODOT appears to have used other types of markers to identify and locate culverts and stormwater facilities before; however, their usage appears to be limited, and not much information is known about them:

* Some highways, such as stretches of [[US Route 101|US-101]] and [[Oregon Route 6|OR-6]] near Tillamook, have white paddles with a white button reflector affixed to the top and the milepoint in black Series B towards the bottom. These almost always appear to be found in locations with guardrails and almost always are accompanied by a Type 1 culvert marker on the ground and/or the guardrail. Many of these appear weathered, indicating that they may be years or decades old.
* A section of [[Oregon Route 224|OR-224]] from roughly Carver to Barton has small yellow markers with the milepoint in black FHWA Series C text and a reflective blue circle below. These appear to mark the locations of culverts or other drainage facilities. The milepoints correspond to the mileage along the Clackamas Highway #171.
* A couple highways in the central Willamette Valley (a section of [[Oregon Route 221|OR-221]] south of Dayton, [[Oregon Route 51|OR-51]] in Independence, possibly more) have small, narrow green markers at locations of culverts. A circular ODOT logo is on top with sections below for other information about the culvert, including milepoint, kilometerpoint, diameter in inches, length in feet, type, description, and reference point in feet. An Oregon Utility Notification Center "Stop - Call Before You Dig!" logo is at the bottom. Curiously, many of these markers along [[Oregon Route 221|OR-221]] omit all information except the description (usually "CULVERT"). For comparison, the one along [[Oregon Route 51|OR-51]] in Independence has the information affixed to the post using stickers; the text is white on a green background in FHWA Series B and/or C.

== County Roads ==

Not all counties place inventory markers on their bridges or at their culverts.

[[File:Mp-county-clackamas-culvert-examples.png|108px|thumb]]
=== Clackamas County ===

Clackamas county does not place inventory markers on its bridges, but does place stickers on the back of object markers (such as OM-3L and OM-3R markers) with its ODOT bridge number.

The county also utilizes two different kinds of culvert markers on its roads:

* White metallic rounded rectangles, marked at culverts in hundredths of a mile
* White delineator wickets embedded in the ground, also marked at culverts in hundredths of a mile

Each of these markers contains the mileage in tenths or hundredths of a mile and a 5-digit county road number. This number can sometimes span two different roads if they comprise a longer route, such as Stafford and Wilsonville Roads.

At jurisdictional boundaries, the white markers can also sometimes be found with "BCM" and "ECM", for "begin county maintenance" and "end county maintenance" respectively, depending on the direction of travel. Mileage may be present on the wicket style of "ECM" markers, and the metal rectangle versions of "BCM" markers contain the road number without a milepost (likely because it's implied to be MP 0). Other variants may exist in the wild.

Zero mileposts can be found in both types.

[[File:Mp-county-clatsop-bridge-examples.png|182px|thumb]]
=== Clatsop County ===

Clatsop County marks its bridges with a small rectangular inventory marker placed on the bridge itself. These markers display the bridge name, ODOT bridge number, Clatsop County bridge number, and the milepoint in white FHWA Series B text on a green background. They also have a "Clatsop County" stamp on them, similar to [[Mileposts#Clatsop County|mileposts placed on county roads around 2015]].

In addition, Clatsop County places street sign blade-sized signs at the bridge itself, mounted on a taller post presumably for motorist assistance. These signs display the waterway name in large text, with the Clatsop County bridge number and bridge name below it in much smaller lettering. All text on this sign is in FHWA Series B. Like the 2015-era mileposts, these also have "Clatsop County" stamped in them, as well as the date of installation written on them in permanent marker; for example, the sign at Humbug Creek was installed in October 2012.

At culverts, Clatsop County uses green wickets with an orange reflective square and the milepoint below in tenths, hundredths or even ''thousandths'' of a mile, without identifying any sort of road name or number. The typeface used is a thinner stroke version of Helvetica Inserat Roman.

[[File:Mp-county-lincoln-bridge-examples.png|49px|thumb]]
=== Lincoln County ===

Lincoln County appears to place bridge markers on its bridges, though the only one currently observed was on the Rocky Creek Bridge on the Otter Crest Loop (old US-101) near Depoe Bay. They are similar in height to ODOT bridge markers, but appear to be narrower. Unlike ODOT markers, they are not reflective, instead featuring a dark green background. In addition, all text on the marker is the same size of yellow-orange FHWA Series B typeface.

These markers have "LINCOLN COUNTY BRIDGE" on top in all caps, and the name of the road (e.g. "Otter Crest Loop") on the bottom in mixed case text. In the middle, various bridge information is present on three lines:

* The top line is the county bridge number, which appears to consist of the county route number, a dash, and a unique identifier (e.g. "311-01").
* The middle line is the ODOT/NBI bridge number, though leading zeroes appear to be dropped.
* The bottom line is the milepost of the bridge.

It is unknown how many bridges in Lincoln County have these markers. It is also unknown how old these markers are; however, since they use lowercase text for the road name, they cannot be older than 2000, when FHWA Series B introduced lowercase characters.

[[File:Mp-county-linn-bridge.png|60px|thumb]]
=== Linn County ===

Linn County places inventory markers on its bridges that displays information like road number, milepoint, bridge number, road name and body of water crossed. These usually appear on both sides of the bridge and use some form of Helvetica for the typeface. Newer versions of these markers use a reflective sheeting, have a border and incorporate rounded corners.

[[File:Mp-county-marion-culvert.png|30px|thumb]]
=== Marion County ===

Marion County rarely places inventory markers on its culverts. As of July 2025, the only known marker is placed along Champoeg Rd. NE westbound as it crosses Ryan Creek near Champoeg State Heritage Area. The retroreflective marker has a white background, with sharp points at the corners except for a rounded lower-left corner. What appears to be the culvert's NBIS number is placed vertically in the center in blue FHWA Series C text. No other road, milepoint or structural information can be gleaned from the marker. According to Google Street View, the marker was placed on a wooden post sometime between September 2012 and May 2019.

It is unknown if other markers, or variations of this one, exist in the county, as well as how long these markers have been in use.

[[File:Mp-county-polk-bridge.png|60px|thumb]]
=== Polk County ===

Polk County places inventory markers on its bridges, usually just a single marker placed behind one of the diagonally striped hazard signs at the corners of the bridge. This MUTCD yellow-colored marker is about 4 inches wide by 8 inches tall and only displays the bridge's NBIS number vertically on the right side in black FHWA Series B text. No other road, milepoint or structural information can be gleaned from the marker, unless there is information on the back where it cannot easily be seen. It is also unknown if other markers, or variations of this one, exist in the county, as well as how long these markers have been in use.

=== Tillamook County ===

Tillamook County places blue inventory markers on bridges it maintains which list the bridge name, the county bridge number (including the county road number in the first segment), the ODOT bridge number, and the body of water being crossed. All text on the markers is in FHWA Series B. While it isn't known at this time when these markers were placed, their reflective background suggests they may have been placed around the same time as the [[Mileposts#Tillamook County|newer reflective mileposts used on county roads]] since around 2015.

[[File:Mp-county-washington-bridge-culvert.png|126px|thumb]]
=== Washington County ===

Washington County marks most of its bridges and culverts with markers similar to [[Mileposts#Washington County|county road identifiers on mileposts]], with the word "ROAD" replaced with "BRIDGE" or "CULVERT" appropriately. The numerals are larger than the road markers, and the legend text appears to be less condensed. Numerals are in Series B, C or D. No other mileage or route identification information can be found on these markers. A newer version of this marker was placed on the Scholls Ferry Road bridge over the Tualatin River when it was replaced in 2008.

== City Roads ==

[[File:Mp-city-beaverton-bridge-culvert-examples.png|258px|thumb]]
=== Beaverton ===

The City of Beaverton has placed at least three different versions of small green markers at its bridges:

* One (possibly older) version has "Beaverton Bridge" in FHWA Series B on top, the City of Beaverton's centennial seal in the middle, and a white box below containing a green "BB-" (presumably for "Beaverton Bridge") and the bridge number in FHWA Series B on the bottom.
* Another (possibly newer) version retains the same "Beaverton Bridge" on top, but with the City of Beaverton's logo in the middle (omitting the "Oregon") and the bridge number in white FHWA Series C lettering on the bottom.
* A third (possibly the newest) version has "BB" (presumably for "Beaverton Bridge") above, the City of Beaverton's logo in the middle (with the "Oregon" this time), and the bridge number below. The "BB" and bridge number are both in white FHWA Series C. The bridge number is also larger than previous versions.

On the first two types of marker, Beaverton appears to use three digits with leading zeroes (e.g. "004") to identify bridges it has built itself; leading zeroes are dropped from the third marker type (e.g. "16"). However, the city may also retain the numbers of bridges it takes over from other jurisdictions. This could be the case with the Johnson Creek Bridge on SW Hart Road, which has the number "19051"; this number more closely resembles those used by Washington County.

In addition to bridges, Beaverton occasionally places similar markers at its culverts. These markers have the design of the "newest" bridge markers, but with "BC" (presumably for "Beaverton Culvert") on top.

[[File:Mp-city-portland-bridge-culvert-examples.png|186px|thumb]]
=== Portland ===

The City of Portland's Bureau of Transportation (PBOT) places inventory markers on many bridges it maintains. These markers feature the logo of either PBOT or its predecessor, the Portland Office of Transportation (PDOT), along with the city's phone number, the road name, the feature it crosses, and a bridge identifier (likely its ODOT number). All text is either FHWA Series B or Series C, aside from the PBOT/PDOT logo which uses condensed versions of both Britannic and Britannic Bold.

In addition, the city's Bureau of Environmental Services (PBES) places markers at culverts. These are white markers with the long edge oriented horizontally. At the top is a blue "City of Portland" in an as-yet unidentified serif font (represented by Goudy Old Style in the example). The PBES logo and city's phone number are on the bottom in the same shade of blue as the "City of Portland" text above. In the middle is presumably the name and some sort of identifier in black Helvetica Bold text.

{{See|article=[[Bridge and Culvert Inventory Markers]]}}

'''Mileposts''', also called '''mile markers''', denote the distance between two termini on a highway or road. On state highways and county and local roads, the design and materials used for mile markers has changed drastically throughout the years.

== Pre-State Highways ==

=== Portland Baseline Mile Makers ===
Not much is known about mileposting of roads in Oregon prior to the creation of the OSHD, but the mile markers along Portland's Stark Street (formerly Baseline Road) are some of the oldest such mileposts in the state.

After John Preston, first Surveyor General for the Territory of Oregon, marked the intersection of the Willamette Baseline and the Willamette Meridian in June 1851, a road was soon built along the baseline east of Portland<ref name="stark-st-markers">Felker, Jeff. [http://starkstreetmarkers.blogspot.com/2008/05/willamette-stone.html "The Willamette Stone and the Baseline Rd Markers,"] ''The Stark Street Mile Markers'' blog, 23 May 2008, last accessed 8 May 2021</ref>. Appropriately called "Baseline Road", it was opened on November 24, 1854<ref name="stark-st-markers" />. Some time after that, 15 stone mileposts were placed eastward along Baseline Road from the courthouse to the Sandy River, one stone per mile, using the Multnomah County Courthouse (between SW 4th/5th Avenues and Main/Salmon Streets) as the zero milepoint<ref name="stark-st-markers" />. While no one is sure who placed them or when they were placed, it is believed to have been done in the 1870s by the United States Army operating out of the barracks on Front Street and Madison Avenue; they used a one-mile long rope tied to a wagon's axle to make the measurement<ref name="stark-st-markers" />.

Surprisingly, 9 of the original 15 markers survive today, which is even more incredible given the amount of widening Baseline Road/Stark Street has undergone the past 150 years; the downside is that none of the markers are likely in their original locations as a result<ref name="stark-st-markers" />. Mile markers 1, 3, 8, 10, 12 and 15 are missing; all others have been preserved, rescued and/or reinstalled at some point in their history. The plaque in Ventura Park lists mile marker 11 as missing; however, it was since recovered in 1998 and re-set in 2000 with additional concrete<ref name="stark-st-markers" />.

It is believed that this process was repeated for roads heading in three other directions from Portland: Northerly along St. Helens Road/Lower Columbia River Highway (present-day [[US Route 30|US-30]]), southerly along a road near the West Side Pacific Highway, and westerly along Jefferson Street/Canyon Road or Burnside Street<ref name="stark-st-markers" />. One mile marker, P7, can be found outside the Capitol Hill branch of the Multnomah Public Library on SW Captiol Highway along the supposed southern route. Otherwise, no other mile markers have been found along any other routing, despite rumors that three mile stones exist along the northerly alignment<ref name="stark-st-markers" />.

== State Highways ==

=== Concrete Mileposts ===

==== Original Mileposts ====
Concrete mileposts were first plotted in 1913 along the entirety of the Columbia River Highway, from Astoria to The Dalles. The zero milepoint was in Portland, at the corner of SW Washington Street and Broadway; from there, mileage increased both easterly to The Dalles and westerly to Astoria<ref name="road-of-difficulties_p27">Taylor, Michael C. ''Road of Difficulties.'' Bear Creek Press, Wallowa (Oregon), 2008, p. 27</ref>. They were triangular in design, about 3-4 feet tall, with the number carved into the two sides facing traffic.

[[File:1924 OSHC-6th-Biennial-Report p78.jpg|250px|thumb|The OSHC included a photo of this section 5 miles south of Salem in their ''Sixth Biennial Report'' as an example of the mileposts they placed around 1924.]]
In 1923, the OSHD audited its major highways, including the Columbia River Highway, to compile a list of features along the roads for recordkeeping and maintenance purposes; these lists became the 1924 "Mile Posting Data" log for each highway, a precursor to straightline charts that ODOT still uses today<ref name="2005_odot-internal-memo">Unknown author. Internal ODOT memo, 2005</ref>. On September 25 that same year, newly appointed Oregon State Highway Engineer Roy A. Klein proposed placing mileposts along "all main state highways" to the OSHC<ref name="oshc_1923-06-26_1548">Oregon State Highway Commission minutes, 26 June 1923, p. 1548</ref><ref name="oshc_1923-09-25_1579-1580">Oregon State Highway Commission minutes, 25 September 1923, pp. 1579-1580</ref>. Klein was instructed by the commission to report on the cost of this proposal at the next meeting, but he would not present his findings until the November 27 meeting — and even then, he only requested (and received approval for) placing them along the Pacific Highway from Portland to the California line<ref name="oshc_1923-09-25_1579-1580" /><ref name="oshc_1923-11-27_1614">Oregon State Highway Commission minutes, 27 November 1923, p. 1614</ref>. Later, on February 5 1924, Klein was authorized by the OSHC to continue his milepost surveys along the West Side Pacific Highway from Portland to Junction City, as well as the Columbia River Highway (and the Old Oregon Trail Highway by extension) from Astoria to Ontario<ref name="oshc_1924-02-05_1643">Oregon State Highway Commission minutes, 5 February 1924, p. 1643</ref>.

The ''Sixth Biennial Report of the Oregon State Highway Commission'', published in 1924, features a photograph between pages 78 and 79 of one such concrete milepost, MP 58, along the Pacific Highway a few miles south of Salem. The report also describes their placement along five major highways, as well as their purpose:

<blockquote>Concrete mile posts indicating the distance from Broadway and Washington streets, Portland, have been set on the entire length of the Pacific and West Side Pacific Highways, also the Upper and Lower Columbia River Highways and Old Oregon Trail through to Ontario. These mile posts, having been accurately set, become an interesting and informative guide to tourists as well as affording valuable aid in designating maintenance operations, etc. Supplementing the mile posts, each bridge, culvert or other structure has been measured in and indicated on the department records with the proper decimal of the mile in which it is located. This permits the immediate location of all bridges and structures<ref name="6th-biennial_p16">''Sixth Biennial Report of the Oregon State Highway Commission'', 1924, p. 16</ref>.</blockquote>

While the report only mentions the highways that would become US-99/99E/99W and US-30, OSHD policy at the time was to place "permanent concrete mileposts on all our main state highways"<ref name="1924_klein-letter-purcell">Klein, Roy letter to C. H. Purcell, 6 August 1924</ref>.

Due to realignments, widenings, theft and other reasons, very few original concrete mileposts have survived to the present day, with even fewer of them in their original locations. By 1987, only three original concrete mileposts existed along the entirety of the old Upper Columbia River Highway, with only two of them (mileposts 14 and 58) still in good condition into the present day<ref name="odot_study-of-hcrh_1987_p64">Oregon Department of Transportation. ''A Study of the Historic Columbia River Highway'', November 1987, p. 64</ref>.

In addition to the highways above, concrete mileposts have also been discovered along former and abandoned alignments of The Dalles-California Highway in The Dalles-Dufur region and a few miles south of Willowdale. Klein was permitted to place a set of concrete mileposts along this highway on September 28, 1926<ref name="oshc_1926-09-28_2054-2055">Oregon State Highway Commission minutes, 28 September 1926, pp. 2054-2055</ref>. The designs of these mileposts are similar to the ones found on the Pacific and Columbia River Highways, but were slightly changed; the points on the triangular columns of these posts appear rounder and visible stamp outlines can be made out around the numbers.

The last known sets of concrete mileposts requested by Klein were for the [[Redwood Highway|Redwood Highway #25]] (now [[US Route 199|US-199]]), [[Sherman Highway|Sherman Highway #42]] (now [[US Route 97|US-97]]) and [[John Day Highway|John Day Highway #5]] (now [[Oregon Route 19|OR-19]] and [[US Route 26|US-26]]), approved on March 8 1929<ref name="oshc_1929-03-08_2462">Oregon State Highway Commission minutes, 8 March 1929, p. 2462</ref>. So far, no concrete mileposts have been found on those highways.

==== Restored Historic Columbia River Highway Mileposts ====
[[File:1981 ochi-report crh-mileposts pp87&89.png|175px|thumb|A comparison of the original CRH concrete mileposts and ones proposed by Diane Ochi in her 1981 report on the highway.]]
The need for milepost restoration along the old Columbia River Highway was identified as far back as 1981. In her National Park Service report ''Columbia River Highway: Options for Conservation and Reuse'', Diane Ochi recommended adding back mileposts along the route as part of a unified signage overhaul along the route<ref name="ochi_1981_p89">Ochi, Diane. [http://npshistory.com/publications/columbia-river-highway.pdf ''Columbia River Highway: Options for Conservation and Reuse''], National Park Service, 1981, p. 89</ref>. The newer mileposts would be of similar design to the original ones, but were more informational and intricate in design and placement:

* When installed, the posts would be oriented to point to the north.
* "Columbia River Highway" would appear underneath the number, rotated clockwise 90 degrees in order to fit on the post.
* Both the number and "Columbia River Highway" would be surrounded by a rounded-rectangular border, beveled at the same depth as the letters (¼-inch).
* The installation or designation year ("1981" in the etching) would be inscribed on top of the post.<ref name="ochi_1981_p89" />

Ochi's grand vision for the new Columbia River Highway mileposts did not come to fruition, but the idea of milepost restoration along the highway lived on. By 1987, the state had allocated $10,000 to ODOT to cast and place concrete replacement mileposts along two state-owned portions of the old highway, the Crown Point Highway and the Mosier-The Dalles Highway<ref name="odot_1987-11_hcrh-study_p119">Gronowski, Nancy H. & Jeanette Kloos. ''A Study of the Historic Columbia River Highway'', Oregon Department of Transportation, November 1987, p. 119</ref>. These mileposts were similar in design and size to the ones originally placed along the highway, but the numbers were thicker and were painted white. Later projects, including the restorations of the Ruthton Point Viaduct and the Mosier Twin Tunnels, also received these mileposts. However, it is not known at this time if recently opened HCRH Trail segments have these stone mileposts on them.

=== Wooden Mileposts ===
At some point after 1929 — possibly due to the onset of the Great Depression — the OSHD started utilizing wooden mileposts on its highways. The earliest designs consisted of wooden logs buried in the ground, with the exposed part painted a light color (likely white) on top and the bottom/unexposed part painted a dark color (likely black). On the lighter part, large dark numerals were painted on the side. The top was pointed. The scope of the usage of these mileposts is unknown at this time, but they have been found on multiple state highways. One (MP 116) was photographed along the John Day Highway #5/OR-19<ref name="orsos_ODOT-79A-068_0181">Oregon Secretary of State, Oregon Records Management Solution. "[https://records.sos.state.or.us/ORSOSWebDrawer/RecordHtml/6402033 John Day Highway With Fossil Mountain mile Post 116 (Wheeler)]." Undated, accessed 13 January 2024</ref>, and another (MP 169) was photographed along the [[Central Oregon Highway|Central Oregon Highway #7]]/[[US Route 20|US-20]] circa June 1955<ref name="oshd_3419">Oregon State Highway Department via ODOT Library. "Central Oregon Highway MP 169." circa June 1955</ref>. It is not immediately known if numbers were painted on both sides (though it would seem likely).

Later versions were square wooden posts with the number carved into the wood, similar to how concrete mileposts have the numbers etched into them. They too were painted white with black numerals and a black portion on the bottom, and also had a pointed tip. One such example that survives as of July 2025 is MP 43 along US-30 slightly east of Cascade Locks, likely placed around 1952 when the Cascade Locks-Herman Creek Road section of the highway was realigned.

In addition to the concrete markers ordered in 1926, wooden markers were also discovered (and removed) along The Dalles-California Highway/US-97<ref name="aaronlitt_2022-05-03">Litt, Aaron F. Facebook Messenger chat with Jonathan Ledbetter, 3 May 2022</ref>. This, along with MP 43 in Cascade Locks using realigned mileage, indicates that concrete mileposts were likely replaced by wooden mileposts due to highway realignment, theft or destruction.

=== MUTCD-Compliant Mileposts ===

[[File:1961 MUTCD-OR-milepost-examples.png|192px|thumb|right]]
==== 1961 Standards ====

The 1961 edition of the MUTCD introduced mileposts into the standard, discussing their purpose, placement, zero-milepost orientation, and design<ref name="1961_mutcd_p110">AASHO. ''[http://www.trafficsign.us/1961mutcd.html Manual for Uniform Traffic Control Devices, 1961 Edition]'', June 1961, p. 110</ref>. Owing to their uniformity of standards, mileposts on Interstate freeways had a very specific color scheme and numeral size:

<blockquote>The Milepost panels are green, with 6-inch white reflectorized numerals<ref name="1961_mutcd_p110" />.</blockquote>

The standard allowed more leeway for non-Interstate highways, allowing three different color schemes and two different numeral sizes:

<blockquote>It is recommended that these be simple panels, without border, having 4- to 6-inch numerals and no other legend. The numerals should be black on a white background or white on a green or black background, with suitable reflectorization<ref name="1961_mutcd_p110" />.</blockquote>

Aside from the colors, numeral sizes, and the lack of border and other legends (which also applied to Interstates), no other guidance was given on other aspects such as shape, size, typeface, or numeral orientation.

When Oregon implemented mileposts according to their interpretation of the 1961 specification, they used green metallic panels 24 inches tall and 8 inches wide, with 6-inch numerals center-aligned descending from the top of the panel. The numerals were in reflectionized FHWA Gothic Series E and were not rotated. The panel was the same size regardless of how many digits were on it and the type of highway it was placed on. Almost none had borders on them.

The prevalence of these mileposts along state highways diminished in the 1980s and 1990s due to reconstruction projects and updated reflectionization standards; as a result, very few of these mileposts remain, occasionally on former state highways turned back over to county control:

* On [[US Route 101|US-101]] in Depoe Bay, two could be found at MP 128 as of 2018, but were removed by 2024. Both were in good condition.
* One can be found on [[Oregon Route 47|OR-47]] outside of Mist at MP 49 as of 2021. It was in excellent condition.
* One can be found on [[Oregon Route 99E|OR-99E]] just north of Hubbard at MP 28 as of 2019. It appeared to be in good condition.
* A few can be found on [[Oregon Route 210|OR-210/Scholls Ferry Road]] between Kinton and Scholls at MP 2 and 3 as of 2021; MP 4 was present into the mid-2010s, and westbound MP 1 was present until the Tualatin River Bridge near Scholls was rebuilt in 2008. All still present in 2021 appeared to be in poor condition, but could also just have been extremely dirty.
* A pair could be found on [[Oregon Route 8|OR-8]] at MP 1 in Beaverton until the late-2010s. These ones were unique in that they had a border around them, a deviation from the 1961 spec. The westbound one was removed sometime around 2017 and the eastbound one around 2020. Both have since been replaced with modern mileposts. Prior to removal they were in good condition.
* One could be found on [[Oregon Route 10|OR-10]] westbound at MP 3 before it was removed sometime after 2002.

Others may still exist elsewhere in the state on present and former alignments.

[[File:1971 MUTCD-OR-milepost-examples.png|192px|thumb|right]]

==== 1971 Standards ====

AASHO revamped their standards in 1971, tightening up the variances in color, shape and size previously allowed. Also, borders and the word "MILE" were added in a complete reversal from the 1961 spec<ref name="1971_mutcd_pp110-111">AASHO. ''[http://www.trafficsign.us/1971mutcd.html Manual for Uniform Traffic Control Devices, 1971 Edition]'', 13 November 1970, pp. 110-111</ref>. The previous requirements for Interstates were rolled into general requirements for freeways in this edition, and required larger mileposts:

<blockquote>Markers shall contain 10-inch white numerals on 12-inch wide vertical green panels with a white border. Panels shall be 24″, 36″, or 48″ in length for one, two, or three digits, respectively, and contain the word MILE<ref name="1971_mutcd_pp164-166">AASHO. ''[http://www.trafficsign.us/1971mutcd.html Manual for Uniform Traffic Control Devices, 1971 Edition]'', 13 November 1970, pp. 164 & 166</ref>.</blockquote>

Markers on non-freeways were just smaller versions of the freeway ones:

<blockquote>Milepost signs shall be vertical panels with 6-inch white numerals, a border and the word MILE in 4-inch letters on a green background and shall be reflectorized<ref name="1971_mutcd_pp110-111" />.</blockquote>

Three sizes were specified, based on how many numbers would be on the post:

* '''D10-1:''' For 1-digit numbers, 12″ × 24″ on freeways<ref name="1971_mutcd_pp164-166" />, 10″ × 18″ elsewhere<ref name="1971_mutcd_pp110-111" />
* '''D10-2:''' For 2-digit numbers, 12″ × 36″ on freeways<ref name="1971_mutcd_pp164-166" />, 10″ × 27″ elsewhere<ref name="1971_mutcd_pp110-111" />
* '''D10-3:''' For 3-digit numbers, 12″ × 48″ on freeways<ref name="1971_mutcd_pp164-166" />, 10″ × 36″ elsewhere<ref name="1971_mutcd_pp110-111" />

Aside from the size of the numbers and the MILE legend, no typeface suggestions were given. However, the example image in the MUTCD itself appears to use FHWA Gothic Series D for the numerals and Series B for the MILE legend<ref name="1971_mutcd_pp110-111" />.

Oregon mostly adopted the milepost standard as defined in the MUTCD. However, the state opted to use the D10-2 2-digit marker for 1-digit mileposts, with the number vertically centered between MILE and the bottom of the post. This practice was utilized on both freeway and non-freeway routes through the mid-2000s, when ODOT started using the D10-1 marker more frequently for single-digit mileposts. Recently completed transportation projects, like the [[Oregon Route 224|Sunrise Expressway]] and the [[Oregon Route 62|Rogue Valley Expressway]], use D10-1 single-digit panels.

Two of Oregon's first major implementations of the 1971 standard mileposts occurred around early 1972, when the entirety of mileposts on [[Interstate 5|Interstates 5]] and [[Interstate 80N|80N]] were replaced. Interstate 5's mileposts were originally from north to south, but needed to be switched to running south-to-north, per 1961 AASHO standards; Interstate 80N's mileposts were being changed to incorporate increased mileage from the selection of the [[Mount Hood Freeway]] corridor. State Highway Engineer R. L. "Rod" Porter estimated that the cost of revising both highways' milepost systems and installing the new mileposts would cost $25,000 total — $11,500 for I-5 and $13,500 for I-80N — and would need to be done with state forces instead of by several contractors<ref name="1971-12-09_rlporter_letter">Porter, R. L. letter to R. E. Simpson, 9 December 1971, p. 1</ref>.

Technically, just about any milepost on a state highway in Oregon that only includes a border, a MILE legend and large numbers on whole miles is a 1971 specification MUTCD milepost. That said, Oregon does have quite a few subtle variations based primarily on number size and typeface, usually FHWA Series C or D. In addition, later MUTCD specs included variations that Oregon has implemented from time to time.

 

[[File:2003 MUTCD-OR-milepost-examples.png|126px|thumb|right]]
==== 2003 Standards ====

The 1971 MUTCD descriptions for mileposts remained more or less the same for more than 30 years, even after a name change to the more generic "reference posts" in 2000. These standards also allowed for fractional mileposts of some kind, using either delimiters or reference posts at consistent intervals. However, they weren't considered part of the milepost system until 2003, when AASHTO introduced them as "intermediate reference location markers". These mileposts have the same design as the 1971 spec, but with an extra section below the mile number that contains the fractional portion, with decimal (such as ".3")<ref name="2003_mutcd_p2D.27">AASHTO. ''[https://mutcd.fhwa.dot.gov/pdfs/2003/pdf-index.htm Manual for Uniform Traffic Control Devices, 2003 Edition]'', November 2003, p. 2D-27</ref>. The decimal portion is always displayed, even on whole numbers where a ".0" is placed in that section.

The 2003 MUTCD defined sizes for freeway and expressway placement, but not for other highways and roads. Their dimensions are estimated based on the original D10 mileposts of comparable size.

* '''D10-1a:''' For 1-digit numbers – 12″ × 36″ on freeways, 10″ × 27″ elsewhere<ref name="2003_mutcd_p2D.27" />
* '''D10-2a:''' For 2-digit numbers – 12″ × 48″ on freeways, 10″ × 36″ elsewhere<ref name="2003_mutcd_p2D.27" />
* '''D10-3a:''' For 3-digit numbers – 12″ × 60″ on freeways, 10″ × 45″ elsewhere<ref name="2003_mutcd_p2D.27" />

Oregon's first implementation of this standard, however, was not for fractional mileposts. Instead, the mileposts were used to differentiate between sections of [[US Route 395|US-395]] where mileposts reset to zero due to [[Mileposting in Oregon|Oregon's dual highway/route system]]. This resetting confused travelers at best and hindered emergency services at worst, so ODOT decided to add letters in the spot on the post where the fraction would normally reside<ref name="2013_odot_abcs-us395-mile-markers">Oregon Department of Transportation. "The A, B, C's of U.S. 395 Mile Markers in Oregon", 15 August 2013</ref>. ODOT initially added them on two sections in late 2008 or early 2009 — the section of US-395 from Pendleton to Mt. Vernon received "B" while the section from John Day to near Burns received "C"<ref name="eastoreg_2008-11-28">''The East Oregonian.'' "[https://www.eastoregonian.com/news/local/odot-assigns-letters-to-parts-of-highway-395/article_0428f1eb-6ce6-58cb-ae49-4f4ffdc0eefe.html ODOT Assigns Letters to Parts of Highway 395]," 28 November 2008, last updated 13 December 2008, last accessed 23 May 2021</ref>. Letter suffixes "D" and "E" were added to two portions from near Riley to the California border by 2013<ref name="2013_odot_abcs-us395-mile-markers" />; these ones omit the line between the numbers and letter, making them effectively like an original D10 milepost with 4 alphanumerics on them.

The letter suffix system was expanded to [[Oregon Route 207|OR-207]] by early 2018, using "A", "B" and "C" along three different sections<ref name="2018_odot_abcs-mile-markers">Oregon Department of Transportation. "The A, B, C's of Mile Markers in Oregon", 5 January 2018</ref>.

As far as actual fractional mileposts are concerned, their first usage in Oregon was on [[US Route 26|US-26]] between Sandy and the junction of [[Oregon Route 35|OR-35]], installed at half-mile intervals in the summer of 2011 as part of and ODOT pilot project<ref name="sandypost_2011-08-09">Hart, Jim. "New Mile Markers Posted Along Highway 26," ''The Sandy Post'', 9 August 2011</ref>. Since then, Oregon has expanded their usage on other highways to improve response times. Freeway-size D10-2a markers has been installed at half-mile intervals in the median of [[Interstate 84|I-84]] through the Columbia River Gorge, and smaller D10-1a mileposts were installed on the Multnomah County section of then-future [[Oregon Route 127|OR-127]] in the summer of 2019<ref name="multco_cornpass_info">Multnomah County. "Cornelius Pass Road Safety Improvements," last updated 18 December 2020, https://multco.us/roads/webform/cornelius-pass-road-safety-improvements, last accessed 8 February 2021</ref>.

ODOT had placed a D10-2a marker at MP 68.9 along US-26 near Clear Creek in the Mount Hood National Forest in an attempt to avoid the "[[Mile 69 Problem]]". Unfortunately, it was removed by October 2022, likely the result of construction along that segment; as of June 2025, it has not been replaced.

An August 2014 [[Interstate 5|I-5]] optimization study recommended installing half-mile markers between Salem and Albany for incident management and towing purposes<ref name="2014_i5_optimization_ch5p2">DKS Associates. "I-5 Optimization Study, Final Report", August 2014, ch. 5 p. 2.</ref>. However, as of 2024 this has yet to come to fruition. Tenth-mile markers were also considered, but ultimately were not recommended<ref name="2014_i5_optimization_tbl4-3">DKS Associates, table 4-3.</ref>.

[[File:2009 MUTCD-OR-milepost-examples.png|188px|thumb|right]]

==== 2009 Standards ====

The 2009 standard added another milepost type, "enhanced reference location signs", to further aid motorists and emergency responders<ref name="2009_mutcd_p296">AASHTO. ''[https://mutcd.fhwa.dot.gov/pdfs/2009r1r2/pdf_index.htm Manual for Uniform Traffic Control Devices, 2009 Edition with Revisions 1 and 2 Incorporated]'', May 2012, p. 296</ref>. These mileposts contained a cardinal direction, route shield and whole mile number. Two different varieties were defined, one for whole numbers (D10-4) and one for fractional miles (D10-5) which included an extra section below the mileage for the decimal part. Both varieties only came in one size, regardless of mile number or highway type:

* '''D10-4:''' For whole miles only – green or blue, 18″ × 54″<ref name="2009_mutcd_p292">AASHTO. ''[https://mutcd.fhwa.dot.gov/pdfs/2009r1r2/pdf_index.htm Manual for Uniform Traffic Control Devices, 2009 Edition with Revisions 1 and 2 Incorporated]'', May 2012, p. 292</ref>
* '''D10-5:''' For whole and fractional miles – green or blue, 18″ × 60″<ref name="2009_mutcd_p292">AASHTO. ''[https://mutcd.fhwa.dot.gov/pdfs/2009r1r2/pdf_index.htm Manual for Uniform Traffic Control Devices, 2009 Edition with Revisions 1 and 2 Incorporated]'', May 2012, p. 292</ref>

Legends need to be at least 6 inches tall and shields need to be at least 12 inches tall<ref name="2009_mutcd_p296" />. For typefaces on both, the examples in the MUTCD showed the cardinal direction and whole mile number in FHWA Series B, and with "MILE" and the fractional mile (if present) in Series C.

Oregon doesn't use these type of mileposts very often, but they are present in the state. D10-5 markers were installed at half-mile intervals along [[Oregon Route 217|OR-217]] in the summer of 2011 as part of the same pilot project that installed [[Mileposts#2003_Standards|2003-spec D10-2a markers]] along US-26<ref name="sandypost_2011-08-09" />. These markers largely matched those in the MUTCD, but used FHWA Series C for the whole mile number instead of Series B. As of 2021 they do not appear to have been implemented along any other freeway within Oregon.

In addition, D10-4 mileposts can be found in a rare non-freeway instance intermittently along [[US Route 20|US-20]] through the Cascades. Installed around 2016 or 2017, these ones more or less follow the MUTCD example typeface-wise. Some examples can be found at [https://goo.gl/maps/Xgk5D7rPji7196dP7 MP 75], [https://goo.gl/maps/dsUjfaQdqq7KNpwy8 MP 80] and [https://goo.gl/maps/X9cXgQXGwT8bNqki9 MP 83].

[[File:2020s 0mp+ODOT-R3-terminal-mp-example.png|126px|thumb|right]]

=== Terminal Mileposts ===
Oregon initially didn't post any mileposts at a highway's termini, save in the rare instance where a highway ended its mileage at or around the whole mile — one such example is MP 50 at the end [[Oregon Route 224|OR-224]] just across the bridge over the Oak Grove Fork of the Clackamas River. Prior to 2000, "BEGIN" and "END" banners were not present on state highways in Oregon at either terminus. For unsigned state routes that continued beyond the end of state maintenance, the change in jurisdiction (if indicated at all) was either indicated by an "END STATE HIGHWAY MAINTENANCE" sign or some sort of county signage indicating the start of their maintenance. The new millennium ushered in a few "END" shield assemblies on some signed state routes, and even a "BEGIN" assembly or two (such as the "BEGIN [[US Route 20|US-20]]" assembly at its western terminus, [[US Route 101|US-101]] in Newport).

At the tail end of the 2010s, Oregon started experimenting with terminal mileposts in different parts of the state. Along the [[Interstate 5|I-5]] corridor, ODOT posted D10-2 zero mileposts along two intersecting signed state highways: At the northern terminus of [[Oregon Route 551|OR-551]] and at the junction of I-5 and [[Oregon Route 99E Business (Salem)|OR-99E Business]] in Keizer. These are possibly the first zero mileposts along a state-maintained highway in Oregon. The "0" numeral (in what looks to be FHWA Series D) is considerably larger than numerals used in standard D10-2 mile markers.

In addition, by June 2021 ODOT Region 3 had marked the ends of some of its unsigned/poorly-signed state maintained highways with distinctive panels. The words "END ODOT" would be stacked on top, followed by the ODOT logo, then "MP" over the terminal milepost number to two decimal spots (or "0.0" at the zero milepoint), and finally the name of the highway over "HWY. ###" — with "###" being the state ''highway'' number, not the state ''route'' number. So far they have been observed at termini on highways in both Coos and Curry County: [[Oregon Route 241|OR-241]], [[Oregon Route 542|OR-542]], [[Oregon Route 250|OR-250]], and [[Oregon Route 251|OR-251]]<ref name="aaroads_2021-06-29">Chris [xonhulu].

</gallery>

=== Miscellany ===

* Rarely, some mileposts will have a "Z" above the number, such as on a section of [[US Route 101|US-101]] near Wheeler. This is due to a highway realignment or cancellation and is used to denote duplicate mileposts along a highway, and is similar to "B"-mileage in Washington or "R"-mileage in California. For additional information on Oregon's milepoint system, see [[Mileposting in Oregon]].

 

== County Roads ==

[[File:Mp-county-clackamas-examples.png|180px|thumb]]
=== Clackamas County ===

Three different kinds of mileposts can be found on Clackamas County roads:

* Green MUTCD D10-2 mileposts for 1- and 2-digit numbers, marked at whole miles
* White metallic rounded rectangles, marked at culverts in hundredths of a mile
* White delineator wickets embedded in the ground, also marked at culverts in hundredths of a mile

Each of these mileposts contains the mileage — whole numbers on green mileposts, tenths or hundredths of a mile on white ones — and a 5-digit county road number. This number can sometimes span two different roads if they comprise a longer route, such as Stafford and Wilsonville Roads.

The green mileposts used to be more prevalent in the 1990s but have been disappearing as they're damaged or otherwise removed. The white markers are much more prominent, but can be more hidden and sometimes don't face traffic.

At jurisdictional boundaries, the white markers can also sometimes be found with "BCM" and "ECM", for "begin county maintenance" and "end county maintenance" respectively, depending on the direction of travel. On the wickets, no other information (such as mileposts or road numbers) are present; the metal rectangle versions of these posts ''can'' contain the road number, but again no mileage is indicated.

Zero mileposts can be found among all three types, though the green ones are much rarer.

[[File:Mp-county-clatsop-examples.png|257px|thumb]]
=== Clatsop County ===

Prior to the mid 2010s, mileposts on Clatsop County roads appeared only on green wickets placed in the vicinity of a culvert. These wickets show the mileage in tenths, hundredths, or even ''thousandths'' of a mile, without identifying any sort of road name or number. The typeface used is a thinner stroke version of Helvetica Inserat Roman.

In early 2015, some roads were provided with mileposts in three new distinct styles, leaving the green wickets intact:

* A standard D10-1 or D10-2 milepost, mounted on a post in the center with numbers in FHWA Series C or D. Some enhancements have also been added:
** The 2-digit year of manufacture or installation is in black in the upper right
** The road name and number are in white on the bottom towards the left
** "Clatsop County" is in black on the lower right
** The month and year of installation may be written in permanent marker somewhere on the milepost
* A different D10-1 (and possibly D10-2) milepost, mounted on a post to the ''side''; in addition, the 2-digit year, "Clatsop County" stamp and written installation date are omitted. On these markers, the numbers are in FHWA Series B.
* A white wicket with a green sticker stating "MILE" and the mile number. All letters and numbers are in condensed FHWA Series C.

Other variations may also exist, but have yet to be discovered or documented.

In addition, [[Bridge and Culvert Inventory Markers#Clatsop County|inventory markers placed on county bridges]] display the milepoint number alongside other bridge information.

[[File:Mp-county-columbia-examples.png|126px|thumb]]

=== Columbia County ===

Columbia County does not place mileposts along all of its roads, but does on some major ones like Apiary Road and Scappoose-Vernonia Highway. When they are placed, they are standard D10-1 and D10-2 mileposts with the numeral in FHWA Series D. No other markings or information appears to be on the signs themselves.

 

[[File:Mp-county-coos.png|60px|thumb]]
=== Coos County ===

Coos County has used their own version of an "enhanced" milepost for at least 20 years, though overall it appears more in line with the 1961 MUTCD spec. It consists of a simple green rectangle 6″ × 18″ with no border or "MILE" legend, with a FHWA Series C numeral roughly centered at the top of the sign. Below the numeral is a square sticker of a Coos County reassurance shield with the road number placed inside. The road number is also in Series C, but the "COOS COUNTY" inside the shield appears to be different weights of Helvetica Neue LT Pro; "COOS" is in 87 Heavy Condensed and "COUNTY" is either 77 Bold Condensed or 67 Medium Condensed.

 

[[File:Mp-county-douglas-examples.png|192px|thumb]]
=== Douglas County ===

Douglas County places its mileposts at mile intervals along many of its county roads, using two distinct styles:

* The first style is similar to the state's 1961 MUTCD spec marker, except it's smaller, shorter and uses Series E(M) for its numerals instead of Series E.
* The second, much more common style follows the 1971 MUTCD spec, using a D10-2 for 1-digit mileages and a D10-3 for 2-digit mileage, using Series B, C or D.

Both mileposts leave a space below the numeral for a sticker or decal of a Douglas County reassurance shield with the road number placed inside, similar to Coos County. However, Douglas County's shields have a yellow background and are entirely in FHWA Gothic fonts; Coos County's shields have a white background, and some of the text is in Helvetica Neue LT Pro.

 

[[File:Mp-county-hoodriver-examples.png|324px|thumb]]
=== Hood River County ===

Hood River County mileposts its roads using a simple green panel with "MP" at the top and the number below it. The same size panel appears to be used for 1- and 2-digit numbers. Mileposts appear to be placed on the side of the road where mileage increases, with a mile marker facing each direction of travel. All characters appear to be in FHWA Series C.

There does appear to be some sort of hundredths marker that the county uses. Similar to other county mile markers, it is topped with "MP", but displays the two hundredths-mileage digits below the integer mile in smaller numbering, making these markers taller than the others. A version with black text on an aluminum background can be found on Baseline Drive at MP 0.46, with "D18 CULV" down the right side on the back; "CULV" indicates this is marking a culvert. Until roughly 2021, when it was replaced during freeway construction, a version with white text on a green background could be seen on Forest Lane at the I-84 overpass in Cascade Locks where the road becomes state-maintained. This one has "F4 END" also down the right side on the back, with "END" indicating the jurisdictional transition. It is currently unknown what "D18" and "F4" stand for, though it's possible they indicate route numbers or some other inventory number. It is also unknown if any other existing hundredths markers have text on their backs.

=== Linn County ===

Linn County doesn't appear to place mileposts along its county roads. However, it does place [[Bridge and Culvert Inventory Markers#Linn County|inventory markers on bridges]] that displays the milepoint alongside other information.

=== Marion County ===

Marion County doesn't regularly place mileposts along its county roads. However, an old-looking MP 5 marker was rediscovered on Cascade Hwy SE just south of its junction with [[Oregon Route 214|OR-214]] as of June 2019. It was present at that location prior to October 2008 and was likely placed within the past 30-40 years, but has since been knocked at an angle. The marker is a standard D10-1 milepost with the numeral in FHWA Series C. The northbound (south-facing) side is much more deteriorated than the southbound (north-facing) side.

Additional research is needed to determine if any more markers exist along Marion County backroads.

[[File:Mp-county-multnomah-examples.png|126px|thumb]]

=== Multnomah County ===

Multnomah County has used standard D10-1 and D10-2 mileposts along its roads since at least the mid-1980s, though they used to be more common than they are now. The large numerals are usually in FHWA Series C, but can also be found in Series D. They are commonly mounted on wooden posts with the top carved into a point, a typical feature of Multnomah County signage.

The county did place D10-1a mileposts at half-mile intervals along [[Oregon Route 127|Cornelius Pass Road]] in 2019, but this was likely done in conjunction with ODOT in preparation to turn it over to state jurisdiction. Multnomah County milepost 5 was confirmed on Cornelius Pass Road at the Washington County line as of May 28, 2021, but was removed by January 2022.

[[File:Mp-county-tillamook-examples.png|270px|thumb]]

=== Tillamook County ===

{{See|article=[[Bridge and Culvert Inventory Markers#Tillamook County|Bridge and Culvert Inventory Markers: Tillamook County]]}}

Prior to about 2015, Tillamook County largely used standard D10-1 and D10-2 mileposts along many of its county roads, with numbers typically using FHWA Series D. In some instances, a D10-1 milepost may have two digits; in other instances, a D10-2 milepost may have one digit. Some D10-2 mileposts had a thicker border and more space between the "MILE" legend and the numbers; the numbers themselves may also use a different FHWA Series, like Series C.

Around 2015, a new variety of milepost started appearing along some county roads, such as Foss Road and Fairview Road. These mileposts were more squarish in appearance with a much thicker white border around them, a much more reflective green background, and one or two digits inside. The numbers are FHWA Series B stretched about 30% wider than usual.

In addition, a smaller third type of milepost has been found on Gods Valley Road at MP 3. This milepost is roughly 6″ × 15″ with a thick white border and uses FHWA Series B in both the "MILE" legend and the number. Whether this type of marker is used on other county roads is unknown at this time.

[[File:Mp-county-umatilla-examples.png|126px|thumb]]

=== Umatilla County ===

Umatilla County appears to place D10-1 and D10-2 mileposts along many of its county roads. The designs are slightly modified from the standard to place "UMATILLA COUNTY" in small FHWA Series C text centered below the numeral on two separate lines, but are otherwise the same as other 1971 MUTCD spec mileposts. No other road information appears to be present on these signs.

 

=== Wasco County ===

Wasco County doesn't appear to place mileposts along its county roads.

[[File:Mp-county-washington.png|60px|thumb]]
=== Washington County ===

{{See|article=[[Bridge and Culvert Inventory Markers#Washington County|Bridge and Culvert Inventory Markers: Washington County]]}}

Mileposts along Washington County roads are pretty rare and usually aren't present at all. When they are, they are simple green rectangles 6″ × 18″ with no border, with "MP" and the number in the same size FHWA Series B typeface. They are usually — though not always — accompanied by a smaller green rectangle 6″ × 10″ with a thin white border bearing the text "WASHINGTON COUNTY ROAD" and the road number, both also in Series B. Due to their weathered appearance in the wild, it's likely these mileposts were placed more than 30 years ago. Only a handful are known to have survived into the 2010s:

{| class="wikitable"

|}

Others may still exist along Washington County backroads.

Older state mileposts can also be found on sections of state routes turned back over to county jurisdiction. 1961 MUTCD specification posts are present as of 2021 at MP 2 and 3 along [[Oregon Route 210|OR-210/Scholls Ferry Road]]; MP 4 near Kinton was present until the mid-2010s. A 1971 spec MP 12 also exists at the north end of Scholls Ferry Road near [[Oregon Route 10|OR-10/Beaverton Hillsdale Highway]]. On [[Oregon Route 10|OR-10/Farmington Road]], a 1971 spec MP 3 was present eastbound as of August 2018; a 1961 spec milepost at that same location westbound was removed sometime after 2002, and other 1971 spec mileposts were removed over a 10-15 year period after that section of OR-10 was relinquished to the county.

Curiously, Washington County placed a D10-1 standard "MILE 1" marker on Scholls Ferry Road in Scholls at milepoint 1 of the old Scholls Highway #143 when the Tualatin River bridge was rebuilt in 2008. These markers — possibly the only MUTCD standard mileposts placed by Washington County — replaced a 1971 spec marker eastbound and a 1961 spec marker westbound.

=== Yamhill County ===

Yamhill County doesn't appear to place mileposts along its county roads.

== Other Jurisdictions ==

=== Native Reservations ===

[[File:Mp-bia-warmsprings-examples.png|258px|thumb]]
==== Warm Springs Reservation ====

Mileposts have been observed along [[Bureau of Indian Affairs Road 3 (Warm Springs Reservation)|BIA-3]] and [[Bureau of Indian Affairs Road 9 (Warm Springs Reservation)|BIA-9]] inside the reservation. They are standard green 1971 D10-1 and D10-2 mileposts, with numerals usually in FHWA Series C. Some variants have been seen, such as using FHWA Series D numerals or using a D10-2 milepost for a single-digit milepoint. Other styles may exist on other BIA roads.

Mileposts appear only to be posted in the direction of increasing mileage, when they are posted at all.

=== National Forests ===

It is unknown at this time if all National Forests in Oregon use mileposts on their roads. However, these ones have been observed:

[[File:Mp-nf-mthood-examples.png|97px|thumb]]
==== Mount Hood National Forest ====

So far, two types of mileposts have been observed along National Forest primary routes in the Mount Hood National Forest. The older type is a simple brown wicket with "MP" across the top and a larger mile number below. All text is in FHWA Series C. If the mile number is larger than 9, the number itself is stacked like a standard milepost. These mileposts have been observed on both [[National Forest Highway 44 (Mount Hood National Forest)|National Forest 44]] and [[National Forest Highway 46 (Mount Hood National Forest)|National Forest 46]]. Varieties found on [[National Forest Highway 43 (Mount Hood National Forest)|National Forest 43]] use stickers for the "MP" in an as-yet-unidentified heavyweight sans-serif font (likely in the Helvetica family), with the number in FHWA Series B. Additionally, mileposts on [[National Forest Highway 42 (Mount Hood National Forest)|National Forest 42]] entirely use stickers featuring that same unidentified font.

In January 2025, a newer milepost design was observed along [[National Forest Highway 57 (Mount Hood National Forest)|National Forest 57]] east of its junction with National Forest 44 and [[Oregon Route 224|Oregon 224]]. This type also uses a brown wicket, but has the word "MILE" on top in small FHWA Series E, the mile number below that in FHWA Series C, and a tiny route number at the bottom in FHWA Series B. The route number is in the format "NFxx", where "xx" is replaced by the route number (e.g., "NF57"). It is unknown if the mile number is stacked when greater than 9. As the area around National Forest 57 was heavily damaged by the Riverside Fire in September 2020, it is theorized that these mileposts were installed sometime afterwards.

No mileposts were observed along [[National Forest Highway 48 (Mount Hood National Forest)|National Forest 48]] between National Forest 43 and [[Oregon Route 35|Oregon 35]] in July 2025.

It is unknown at this time if mileposts exist on National Forest primary routes apart from National Forest 42, 43, 44, 46 and 57, or if they appear on secondary or tertiary forest roads and trials. It is also unknown at this time if the newer milepost design will be applied to other primary routes within the forest.

=== State Forest and Timber Lands ===

It is unknown at this time if all state forests in Oregon use mileposts on their roads. However, these ones have been observed:

[[File:Mp-sf-clatsop-examples.png|160px|thumb]]
==== Clatsop State Forest ====

Some roads within the Tillamook State Forest have mileposts, usually nailed to a tree. They are yellow rectangular signs with a large black mile number centered on the sign. The number is usually in Helvetica Inserat, but other fonts like Franklin Gothic Heavy may be used. The signs don't contain any other information that identifies the road.

Most likely, these mileposts are placed by the Oregon Department of Forestry to aid both recreational vehicles and logging trucks. They are usually placed at half-mile intervals, but can sometimes go missing. Usually, mileposts are posted in pairs so as to be seen in both directions of travel.

On occasion, the milepost will be surrounded by spray paint on the tree to improve visibility.

Unlike other jurisdictions, fractional mileposts use vulgar fractions (e.g., ½) instead of decimal fractions (e.g., 0.5). The vulgar fraction portion appears to be in a condensed version of Helvetica in medium weight.

[[File:Mp-sf-tillamook-examples.png|111px|thumb]]
==== Tillamook State Forest ====

Some roads within the Tillamook State Forest have mileposts, usually nailed to a tree. They are yellow rectangular signs with a large black mile number centered on the sign. The number is usually in Helvetica or a typeface similar to Frutiger or Calibri, but other fonts may be used. The signs don't contain any other information that identifies the road.

As the mileposts persist on roads that leave State Forest lands, it is unknown who places the mileposts along these roads. Most likely, they are placed by the Oregon Department of Forestry to aid both recreational vehicles and logging trucks. They are usually placed at half-mile intervals, but can sometimes go missing. Usually, mileposts are posted in pairs so as to be seen in both directions of travel.

On occasion, the milepost will be spray-painted on a tree instead of using a sign.

Bridge and Culvert Inventory Markers

2026-01-09T02:26:18Z

Jonathan: Updated Clackamas County and stubbed out Lincoln County

'''Bridge and Culvert Inventory Markers''' are signs that identify bridges and culverts for jurisdictional maintenance purposes and occasionally to assist the travelling public. Oregon has placed inventory markers on bridges since around the year 2000, but some counties and cities have used them in decades prior.

== State Highways ==
[[File:Odot-bridge-inventory-marker-examples.png|258px|thumb]]
=== Bridge Inventory Markers ===

By 2001, ODOT started placing standardized inventory markers at some bridges and overpasses. ODOT's logo is at the top, with a phone number underneath it. Information about the bridge — route number, highway number, milepoint, and ODOT bridge number — is placed in the middle, with the name of the feature being crossed below that. Variations do exist, likely as a result of the contractors used on various projects:

* The "ODOT" in the ODOT logo used to be in Helvetica, but has changed typeface in recent years. All other text is in FHWA Series B, though often times it is condensed even more to fit additional information.
* Phone numbers change depending on the location of the marker and are included as a public safety service. Numbers currently documented include:
** 503-378-2299: 24/7 ODOT Dispatch Center
** 503-283-5859: ODOT Region 1 (Portland Metro Area) Dispatch Center
** 503-362-0457: ODOT Region 2 (NW Oregon) Dispatch Center
** 541-296-2215: ODOT Maintenance District 9 (The Dalles)
* Phone numbers sometimes have dashes in between them.
* Some markers display the text "EMERGENCY ONLY" below the phone number in Series D.
* Interstate routes are displayed with an "I-" in front of the number; by comparison, US and state routes are usually not prefixed by "US" or "OR".
* Milepoints are usually to two decimal points, though some markers exist with only a single decimal point.
* All letters on the markers used to be in all caps; however, the intersecting feature text can sometimes be found in mixed case, such as in markers along the [[Oregon Route 18|Newberg-Dundee Bypass]].
* The text in the intersecting feature section is usually centered, but can sometimes also be left-aligned.
* Milepoints can be negative. If this is the case, they will be displayed with a minus sign in front of the milepoint (e.g. MP -0.52). Negative mileage used to be known as "X-mileage", though there are no known inventory markers that use an "X" instead of a "-".

While many of ODOT's inventory markers legibly display correct information, quite a few do not:

* Some markers place the highway number in the "RTE" section and vice versa – for example, the marker at Mills Bridge on [[Oregon Route 6|OR-6]] displays Route 37 and Highway #6
* Some markers display the wrong route number – for example, the marker on [[Oregon Route 202|OR-202]] across Beneke Creek erroneously displays [[Oregon Route 47|OR-47]] in the "RTE" section
* Some markers on unsigned or formerly-unsigned state routes place the route number in the "RTE" section, but place a condensed abbreviation of the highway name in "HWY" – for example, markers on [[Oregon Route 103|OR-103]] display "Fishhawk F" in illegibly-small condensed Type B
* Some markers display a non-existent route – for example, markers on [[Oregon Route 194|OR-194]] erroneously state they are on "US-51"
* Some markers display redundant information – for example, some markers on OR-18 display the highway number and/or milepoint inside the intersecting feature section in addition to their usual spots

=== Culvert and Stormwater Facility Markers ===

Around 2013, ODOT started placing standardized markers at culverts and stormwater facilities. For culverts, two types of markers are defined in [https://www.oregon.gov/odot/engineering/202207/RD398.pdf ODOT Standard Drawing RD398], aptly named Type 1 and Type 2.

* '''Type 1''' markers are 4″ × 6–12″ strips of green thermoplastic tape affixed to the road, with no other information added.
* '''Type 2''' markers are 3½″ × 13¼″ white panels with a green stripe at the top. "ODOT" appears above the stripe. A number appears below the stripe — either the Drainage Facility ID (or "DFI number") if the culvert span is less than 6 feet, or the Bridge Structure ID if the culvert span is between 6 and 20 feet. Below the number is the culvert milepoint. All text on the marker is FHWA Series C, called "Type C font" in the drawing.

Stormwater facilities have three types of markers defined in [https://www.oregon.gov/odot/engineering/202207/RD399.pdf ODOT Standard Drawing RD399], named Type S1, S2 and S3.

* '''Type S1''' markers are flexible plastic posts embedded into the ground in two colors, red and green. Red posts signify the start of a stormwater facility maintenance area, and green posts signify the end of the maintenance area. Dimensions are the same as [https://www.oregon.gov/odot/engineering/202207/TM570.pdf ODOT TM570 Type 2 flexible plastic posts], but these omit the 4″ reflective sheeting bands. No other information is added to these posts.
* '''Type S2''' markers are the same size as the Type 2 culvert markers above, and have a similar design. A Type S2's top color band is blue instead of green, and the milepoint is replaced by a 5″ × ¼″ black stripe which can be optionally turned into an arrow to indicate the direction or location of the stormwater facility. Otherwise, both Type 2 and Type S2 display the same information.
* '''Type S3''' markers are essentially DFI numbers stamped onto access covers like manholes and vaults to identify underground stormwater facilities. For durability, ink is not used.

ODOT appears to have used other types of markers to identify and locate culverts and stormwater facilities before; however, their usage appears to be limited, and not much information is known about them:

* Some highways, such as stretches of [[US Route 101|US-101]] and [[Oregon Route 6|OR-6]] near Tillamook, have white paddles with a white button reflector affixed to the top and the milepoint in black Series B towards the bottom. These almost always appear to be found in locations with guardrails and almost always are accompanied by a Type 1 culvert marker on the ground and/or the guardrail. Many of these appear weathered, indicating that they may be years or decades old.
* A section of [[Oregon Route 224|OR-224]] from roughly Carver to Barton has small yellow markers with the milepoint in black FHWA Series C text and a reflective blue circle below. These appear to mark the locations of culverts or other drainage facilities. The milepoints correspond to the mileage along the Clackamas Highway #171.
* A couple highways in the central Willamette Valley (a section of [[Oregon Route 221|OR-221]] south of Dayton, [[Oregon Route 51|OR-51]] in Independence, possibly more) have small, narrow green markers at locations of culverts. A circular ODOT logo is on top with sections below for other information about the culvert, including milepoint, kilometerpoint, diameter in inches, length in feet, type, description, and reference point in feet. An Oregon Utility Notification Center "Stop - Call Before You Dig!" logo is at the bottom. Curiously, many of these markers along [[Oregon Route 221|OR-221]] omit all information except the description (usually "CULVERT"). For comparison, the one along [[Oregon Route 51|OR-51]] in Independence has the information affixed to the post using stickers; the text is white on a green background in FHWA Series B and/or C.

== County Roads ==

Not all counties place inventory markers on their bridges or at their culverts.

[[File:Mp-county-clackamas-culvert-examples.png|108px|thumb]]
=== Clackamas County ===

Clackamas county does not place inventory markers on its bridges, but does place stickers on the back of object markers (such as OM-3L and OM-3R markers) with its ODOT bridge number.

The county also utilizes two different kinds of culvert markers on its roads:

* White metallic rounded rectangles, marked at culverts in hundredths of a mile
* White delineator wickets embedded in the ground, also marked at culverts in hundredths of a mile

Each of these markers contains the mileage in tenths or hundredths of a mile and a 5-digit county road number. This number can sometimes span two different roads if they comprise a longer route, such as Stafford and Wilsonville Roads.

At jurisdictional boundaries, the white markers can also sometimes be found with "BCM" and "ECM", for "begin county maintenance" and "end county maintenance" respectively, depending on the direction of travel. Mileage may be present on the wicket style of "ECM" markers, and the metal rectangle versions of "BCM" markers contain the road number without a milepost (likely because it's implied to be MP 0). Other variants may exist in the wild.

Zero mileposts can be found in both types.

[[File:Mp-county-clatsop-bridge-examples.png|182px|thumb]]
=== Clatsop County ===

Clatsop County marks its bridges with a small rectangular inventory marker placed on the bridge itself. These markers display the bridge name, ODOT bridge number, Clatsop County bridge number, and the milepoint in white FHWA Series B text on a green background. They also have a "Clatsop County" stamp on them, similar to [[Mileposts#Clatsop County|mileposts placed on county roads around 2015]].

In addition, Clatsop County places street sign blade-sized signs at the bridge itself, mounted on a taller post presumably for motorist assistance. These signs display the waterway name in large text, with the Clatsop County bridge number and bridge name below it in much smaller lettering. All text on this sign is in FHWA Series B. Like the 2015-era mileposts, these also have "Clatsop County" stamped in them, as well as the date of installation written on them in permanent marker; for example, the sign at Humbug Creek was installed in October 2012.

At culverts, Clatsop County uses green wickets with an orange reflective square and the milepoint below in tenths, hundredths or even ''thousandths'' of a mile, without identifying any sort of road name or number. The typeface used is a thinner stroke version of Helvetica Inserat Roman.

=== Lincoln County ===

{{stub|part=section}}

 

[[File:Mp-county-linn-bridge.png|60px|thumb]]
=== Linn County ===

Linn County places inventory markers on its bridges that displays information like road number, milepoint, bridge number, road name and body of water crossed. These usually appear on both sides of the bridge and use some form of Helvetica for the typeface. Newer versions of these markers use a reflective sheeting, have a border and incorporate rounded corners.

[[File:Mp-county-marion-culvert.png|30px|thumb]]
=== Marion County ===

Marion County rarely places inventory markers on its culverts. As of July 2025, the only known marker is placed along Champoeg Rd. NE westbound as it crosses Ryan Creek near Champoeg State Heritage Area. The retroreflective marker has a white background, with sharp points at the corners except for a rounded lower-left corner. What appears to be the culvert's NBIS number is placed vertically in the center in blue FHWA Series C text. No other road, milepoint or structural information can be gleaned from the marker. According to Google Street View, the marker was placed on a wooden post sometime between September 2012 and May 2019.

It is unknown if other markers, or variations of this one, exist in the county, as well as how long these markers have been in use.

[[File:Mp-county-polk-bridge.png|60px|thumb]]
=== Polk County ===

Polk County places inventory markers on its bridges, usually just a single marker placed behind one of the diagonally striped hazard signs at the corners of the bridge. This MUTCD yellow-colored marker is about 4 inches wide by 8 inches tall and only displays the bridge's NBIS number vertically on the right side in black FHWA Series B text. No other road, milepoint or structural information can be gleaned from the marker, unless there is information on the back where it cannot easily be seen. It is also unknown if other markers, or variations of this one, exist in the county, as well as how long these markers have been in use.

[[File:Mp-county-tillamook-bridge.png|107px|thumb]]
=== Tillamook County ===

Tillamook County places blue inventory markers on bridges it maintains which list the bridge name, the county bridge number (including the county road number in the first segment), the ODOT bridge number, and the body of water being crossed. All text on the markers is in FHWA Series B. While it isn't known at this time when these markers were placed, their reflective background suggests they may have been placed around the same time as the [[Mileposts#Tillamook County|newer reflective mileposts used on county roads]] since around 2015.

[[File:Mp-county-washington-bridge-culvert.png|126px|thumb]]
=== Washington County ===

Washington County marks most of its bridges and culverts with markers similar to [[Mileposts#Washington County|county road identifiers on mileposts]], with the word "ROAD" replaced with "BRIDGE" or "CULVERT" appropriately. The numerals are larger than the road markers, and the legend text appears to be less condensed. Numerals are in Series B, C or D. No other mileage or route identification information can be found on these markers. A newer version of this marker was placed on the Scholls Ferry Road bridge over the Tualatin River when it was replaced in 2008.

== City Roads ==

[[File:Mp-city-beaverton-bridge-culvert-examples.png|258px|thumb]]
=== Beaverton ===

The City of Beaverton has placed at least three different versions of small green markers at its bridges:

* One (possibly older) version has "Beaverton Bridge" in FHWA Series B on top, the City of Beaverton's centennial seal in the middle, and a white box below containing a green "BB-" (presumably for "Beaverton Bridge") and the bridge number in FHWA Series B on the bottom.
* Another (possibly newer) version retains the same "Beaverton Bridge" on top, but with the City of Beaverton's logo in the middle (omitting the "Oregon") and the bridge number in white FHWA Series C lettering on the bottom.
* A third (possibly the newest) version has "BB" (presumably for "Beaverton Bridge") above, the City of Beaverton's logo in the middle (with the "Oregon" this time), and the bridge number below. The "BB" and bridge number are both in white FHWA Series C. The bridge number is also larger than previous versions.

On the first two types of marker, Beaverton appears to use three digits with leading zeroes (e.g. "004") to identify bridges it has built itself; leading zeroes are dropped from the third marker type (e.g. "16"). However, the city may also retain the numbers of bridges it takes over from other jurisdictions. This could be the case with the Johnson Creek Bridge on SW Hart Road, which has the number "19051"; this number more closely resembles those used by Washington County.

In addition to bridges, Beaverton occasionally places similar markers at its culverts. These markers have the design of the "newest" bridge markers, but with "BC" (presumably for "Beaverton Culvert") on top.

[[File:Mp-city-portland-bridge-culvert-examples.png|186px|thumb]]
=== Portland ===

The City of Portland's Bureau of Transportation (PBOT) places inventory markers on many bridges it maintains. These markers feature the logo of either PBOT or its predecessor, the Portland Office of Transportation (PDOT), along with the city's phone number, the road name, the feature it crosses, and a bridge identifier (likely its ODOT number). All text is either FHWA Series B or Series C, aside from the PBOT/PDOT logo which uses condensed versions of both Britannic and Britannic Bold.

In addition, the city's Bureau of Environmental Services (PBES) places markers at culverts. These are white markers with the long edge oriented horizontally. At the top is a blue "City of Portland" in an as-yet unidentified serif font (represented by Goudy Old Style in the example). The PBES logo and city's phone number are on the bottom in the same shade of blue as the "City of Portland" text above. In the middle is presumably the name and some sort of identifier in black Helvetica Bold text.

{{See|about=the usage and evolution of physical mile markers in Oregon|for=an explanation of Oregon's milepoint system|article=[[Mileposting in Oregon]]}}
{{See|article=[[Bridge and Culvert Inventory Markers]]}}

'''Mileposts''', also called '''mile markers''', denote the distance between two termini on a highway or road. On state highways and county and local roads, the design and materials used for mile markers has changed drastically throughout the years.

== Pre-State Highways ==

=== Portland Baseline Mile Makers ===
Not much is known about mileposting of roads in Oregon prior to the creation of the OSHD, but the mile markers along Portland's Stark Street (formerly Baseline Road) are some of the oldest such mileposts in the state.

After John Preston, first Surveyor General for the Territory of Oregon, marked the intersection of the Willamette Baseline and the Willamette Meridian in June 1851, a road was soon built along the baseline east of Portland<ref name="stark-st-markers">Felker, Jeff. [http://starkstreetmarkers.blogspot.com/2008/05/willamette-stone.html "The Willamette Stone and the Baseline Rd Markers,"] ''The Stark Street Mile Markers'' blog, 23 May 2008, last accessed 8 May 2021</ref>. Appropriately called "Baseline Road", it was opened on November 24, 1854<ref name="stark-st-markers" />. Some time after that, 15 stone mileposts were placed eastward along Baseline Road from the courthouse to the Sandy River, one stone per mile, using the Multnomah County Courthouse (between SW 4th/5th Avenues and Main/Salmon Streets) as the zero milepoint<ref name="stark-st-markers" />. While no one is sure who placed them or when they were placed, it is believed to have been done in the 1870s by the United States Army operating out of the barracks on Front Street and Madison Avenue; they used a one-mile long rope tied to a wagon's axle to make the measurement<ref name="stark-st-markers" />.

Surprisingly, 9 of the original 15 markers survive today, which is even more incredible given the amount of widening Baseline Road/Stark Street has undergone the past 150 years; the downside is that none of the markers are likely in their original locations as a result<ref name="stark-st-markers" />. Mile markers 1, 3, 8, 10, 12 and 15 are missing; all others have been preserved, rescued and/or reinstalled at some point in their history. The plaque in Ventura Park lists mile marker 11 as missing; however, it was since recovered in 1998 and re-set in 2000 with additional concrete<ref name="stark-st-markers" />.

It is believed that this process was repeated for roads heading in three other directions from Portland: Northerly along St. Helens Road/Lower Columbia River Highway (present-day [[US Route 30|US-30]]), southerly along a road near the West Side Pacific Highway, and westerly along Jefferson Street/Canyon Road or Burnside Street<ref name="stark-st-markers" />. One mile marker, P7, can be found outside the Capitol Hill branch of the Multnomah Public Library on SW Captiol Highway along the supposed southern route. Otherwise, no other mile markers have been found along any other routing, despite rumors that three mile stones exist along the northerly alignment<ref name="stark-st-markers" />.

== State Highways ==

=== Concrete Mileposts ===

==== Original Mileposts ====
Concrete mileposts were first plotted in 1913 along the entirety of the Columbia River Highway, from Astoria to The Dalles. The zero milepoint was in Portland, at the corner of SW Washington Street and Broadway; from there, mileage increased both easterly to The Dalles and westerly to Astoria<ref name="road-of-difficulties_p27">Taylor, Michael C. ''Road of Difficulties.'' Bear Creek Press, Wallowa (Oregon), 2008, p. 27</ref>. They were triangular in design, about 3-4 feet tall, with the number carved into the two sides facing traffic.

[[File:1924 OSHC-6th-Biennial-Report p78.jpg|250px|thumb|The OSHC included a photo of this section 5 miles south of Salem in their ''Sixth Biennial Report'' as an example of the mileposts they placed around 1924.]]
In 1923, the OSHD audited its major highways, including the Columbia River Highway, to compile a list of features along the roads for recordkeeping and maintenance purposes; these lists became the 1924 "Mile Posting Data" log for each highway, a precursor to straightline charts that ODOT still uses today<ref name="2005_odot-internal-memo">Unknown author. Internal ODOT memo, 2005</ref>. On September 25 that same year, newly appointed Oregon State Highway Engineer Roy A. Klein proposed placing mileposts along "all main state highways" to the OSHC<ref name="oshc_1923-06-26_1548">Oregon State Highway Commission minutes, 26 June 1923, p. 1548</ref><ref name="oshc_1923-09-25_1579-1580">Oregon State Highway Commission minutes, 25 September 1923, pp. 1579-1580</ref>. Klein was instructed by the commission to report on the cost of this proposal at the next meeting, but he would not present his findings until the November 27 meeting — and even then, he only requested (and received approval for) placing them along the Pacific Highway from Portland to the California line<ref name="oshc_1923-09-25_1579-1580" /><ref name="oshc_1923-11-27_1614">Oregon State Highway Commission minutes, 27 November 1923, p. 1614</ref>. Later, on February 5 1924, Klein was authorized by the OSHC to continue his milepost surveys along the West Side Pacific Highway from Portland to Junction City, as well as the Columbia River Highway (and the Old Oregon Trail Highway by extension) from Astoria to Ontario<ref name="oshc_1924-02-05_1643">Oregon State Highway Commission minutes, 5 February 1924, p. 1643</ref>.

The ''Sixth Biennial Report of the Oregon State Highway Commission'', published in 1924, features a photograph between pages 78 and 79 of one such concrete milepost, MP 58, along the Pacific Highway a few miles south of Salem. The report also describes their placement along five major highways, as well as their purpose:

<blockquote>Concrete mile posts indicating the distance from Broadway and Washington streets, Portland, have been set on the entire length of the Pacific and West Side Pacific Highways, also the Upper and Lower Columbia River Highways and Old Oregon Trail through to Ontario. These mile posts, having been accurately set, become an interesting and informative guide to tourists as well as affording valuable aid in designating maintenance operations, etc. Supplementing the mile posts, each bridge, culvert or other structure has been measured in and indicated on the department records with the proper decimal of the mile in which it is located. This permits the immediate location of all bridges and structures<ref name="6th-biennial_p16">''Sixth Biennial Report of the Oregon State Highway Commission'', 1924, p. 16</ref>.</blockquote>

While the report only mentions the highways that would become US-99/99E/99W and US-30, OSHD policy at the time was to place "permanent concrete mileposts on all our main state highways"<ref name="1924_klein-letter-purcell">Klein, Roy letter to C. H. Purcell, 6 August 1924</ref>.

Due to realignments, widenings, theft and other reasons, very few original concrete mileposts have survived to the present day, with even fewer of them in their original locations. By 1987, only three original concrete mileposts existed along the entirety of the old Upper Columbia River Highway, with only two of them (mileposts 14 and 58) still in good condition into the present day<ref name="odot_study-of-hcrh_1987_p64">Oregon Department of Transportation. ''A Study of the Historic Columbia River Highway'', November 1987, p. 64</ref>.

In addition to the highways above, concrete mileposts have also been discovered along former and abandoned alignments of The Dalles-California Highway in The Dalles-Dufur region and a few miles south of Willowdale. Klein was permitted to place a set of concrete mileposts along this highway on September 28, 1926<ref name="oshc_1926-09-28_2054-2055">Oregon State Highway Commission minutes, 28 September 1926, pp. 2054-2055</ref>. The designs of these mileposts are similar to the ones found on the Pacific and Columbia River Highways, but were slightly changed; the points on the triangular columns of these posts appear rounder and visible stamp outlines can be made out around the numbers.

The last known sets of concrete mileposts requested by Klein were for the [[Redwood Highway|Redwood Highway #25]] (now [[US Route 199|US-199]]), [[Sherman Highway|Sherman Highway #42]] (now [[US Route 97|US-97]]) and [[John Day Highway|John Day Highway #5]] (now [[Oregon Route 19|OR-19]] and [[US Route 26|US-26]]), approved on March 8 1929<ref name="oshc_1929-03-08_2462">Oregon State Highway Commission minutes, 8 March 1929, p. 2462</ref>. So far, no concrete mileposts have been found on those highways.

==== Restored Historic Columbia River Highway Mileposts ====
[[File:1981 ochi-report crh-mileposts pp87&89.png|175px|thumb|A comparison of the original CRH concrete mileposts and ones proposed by Diane Ochi in her 1981 report on the highway.]]
The need for milepost restoration along the old Columbia River Highway was identified as far back as 1981. In her National Park Service report ''Columbia River Highway: Options for Conservation and Reuse'', Diane Ochi recommended adding back mileposts along the route as part of a unified signage overhaul along the route<ref name="ochi_1981_p89">Ochi, Diane. [http://npshistory.com/publications/columbia-river-highway.pdf ''Columbia River Highway: Options for Conservation and Reuse''], National Park Service, 1981, p. 89</ref>. The newer mileposts would be of similar design to the original ones, but were more informational and intricate in design and placement:

* When installed, the posts would be oriented to point to the north.
* "Columbia River Highway" would appear underneath the number, rotated clockwise 90 degrees in order to fit on the post.
* Both the number and "Columbia River Highway" would be surrounded by a rounded-rectangular border, beveled at the same depth as the letters (¼-inch).
* The installation or designation year ("1981" in the etching) would be inscribed on top of the post.<ref name="ochi_1981_p89" />

Ochi's grand vision for the new Columbia River Highway mileposts did not come to fruition, but the idea of milepost restoration along the highway lived on. By 1987, the state had allocated $10,000 to ODOT to cast and place concrete replacement mileposts along two state-owned portions of the old highway, the Crown Point Highway and the Mosier-The Dalles Highway<ref name="odot_1987-11_hcrh-study_p119">Gronowski, Nancy H. & Jeanette Kloos. ''A Study of the Historic Columbia River Highway'', Oregon Department of Transportation, November 1987, p. 119</ref>. These mileposts were similar in design and size to the ones originally placed along the highway, but the numbers were thicker and were painted white. Later projects, including the restorations of the Ruthton Point Viaduct and the Mosier Twin Tunnels, also received these mileposts. However, it is not known at this time if recently opened HCRH Trail segments have these stone mileposts on them.

=== Wooden Mileposts ===
At some point after 1929 — possibly due to the onset of the Great Depression — the OSHD started utilizing wooden mileposts on its highways. The earliest designs consisted of wooden logs buried in the ground, with the exposed part painted a light color (likely white) on top and the bottom/unexposed part painted a dark color (likely black). On the lighter part, large dark numerals were painted on the side. The top was pointed. The scope of the usage of these mileposts is unknown at this time, but they have been found on multiple state highways.

"Central Oregon Highway MP 169." circa June 1955</ref>. It is not immediately known if numbers were painted on both sides (though it would seem likely).

Later versions were square wooden posts with the number carved into the wood, similar to how concrete mileposts have the numbers etched into them. They too were painted white with black numerals and a black portion on the bottom, and also had a pointed tip. One such example that survives as of July 2025 is MP 43 along US-30 slightly east of Cascade Locks, likely placed around 1952 when the Cascade Locks-Herman Creek Road section of the highway was realigned.

In addition to the concrete markers ordered in 1926, wooden markers were also discovered (and removed) along The Dalles-California Highway/US-97<ref name="aaronlitt_2022-05-03">Litt, Aaron F. Facebook Messenger chat with Jonathan Ledbetter, 3 May 2022</ref>. This, along with MP 43 in Cascade Locks using realigned mileage, indicates that concrete mileposts were likely replaced by wooden mileposts due to highway realignment, theft or destruction.

=== MUTCD-Compliant Mileposts ===

[[File:1961 MUTCD-OR-milepost-examples.png|192px|thumb|right]]
==== 1961 Standards ====

The 1961 edition of the MUTCD introduced mileposts into the standard, discussing their purpose, placement, zero-milepost orientation, and design<ref name="1961_mutcd_p110">AASHO. ''[http://www.trafficsign.us/1961mutcd.html Manual for Uniform Traffic Control Devices, 1961 Edition]'', June 1961, p. 110</ref>. Owing to their uniformity of standards, mileposts on Interstate freeways had a very specific color scheme and numeral size:

<blockquote>The Milepost panels are green, with 6-inch white reflectorized numerals<ref name="1961_mutcd_p110" />.</blockquote>

The standard allowed more leeway for non-Interstate highways, allowing three different color schemes and two different numeral sizes:

<blockquote>It is recommended that these be simple panels, without border, having 4- to 6-inch numerals and no other legend. The numerals should be black on a white background or white on a green or black background, with suitable reflectorization<ref name="1961_mutcd_p110" />.</blockquote>

Aside from the colors, numeral sizes, and the lack of border and other legends (which also applied to Interstates), no other guidance was given on other aspects such as shape, size, typeface, or numeral orientation.

When Oregon implemented mileposts according to their interpretation of the 1961 specification, they used green metallic panels 24 inches tall and 8 inches wide, with 6-inch numerals center-aligned descending from the top of the panel. The numerals were in reflectionized FHWA Gothic Series E and were not rotated. The panel was the same size regardless of how many digits were on it and the type of highway it was placed on. Almost none had borders on them.

The prevalence of these mileposts along state highways diminished in the 1980s and 1990s due to reconstruction projects and updated reflectionization standards; as a result, very few of these mileposts remain, occasionally on former state highways turned back over to county control:

* On [[US Route 101|US-101]] in Depoe Bay, two could be found at MP 128 as of 2018, but were removed by 2024. Both were in good condition.
* One can be found on [[Oregon Route 47|OR-47]] outside of Mist at MP 49 as of 2021. It was in excellent condition.
* One can be found on [[Oregon Route 99E|OR-99E]] just north of Hubbard at MP 28 as of 2019. It appeared to be in good condition.
* A few can be found on [[Oregon Route 210|OR-210/Scholls Ferry Road]] between Kinton and Scholls at MP 2 and 3 as of 2021; MP 4 was present into the mid-2010s, and westbound MP 1 was present until the Tualatin River Bridge near Scholls was rebuilt in 2008. All still present in 2021 appeared to be in poor condition, but could also just have been extremely dirty.
* A pair could be found on [[Oregon Route 8|OR-8]] at MP 1 in Beaverton until the late-2010s. These ones were unique in that they had a border around them, a deviation from the 1961 spec. The westbound one was removed sometime around 2017 and the eastbound one around 2020. Both have since been replaced with modern mileposts. Prior to removal they were in good condition.
* One could be found on [[Oregon Route 10|OR-10]] westbound at MP 3 before it was removed sometime after 2002.

Others may still exist elsewhere in the state on present and former alignments.

[[File:1971 MUTCD-OR-milepost-examples.png|192px|thumb|right]]

==== 1971 Standards ====

AASHO revamped their standards in 1971, tightening up the variances in color, shape and size previously allowed. Also, borders and the word "MILE" were added in a complete reversal from the 1961 spec<ref name="1971_mutcd_pp110-111">AASHO. ''[http://www.trafficsign.us/1971mutcd.html Manual for Uniform Traffic Control Devices, 1971 Edition]'', 13 November 1970, pp. 110-111</ref>. The previous requirements for Interstates were rolled into general requirements for freeways in this edition, and required larger mileposts:

<blockquote>Markers shall contain 10-inch white numerals on 12-inch wide vertical green panels with a white border. Panels shall be 24″, 36″, or 48″ in length for one, two, or three digits, respectively, and contain the word MILE<ref name="1971_mutcd_pp164-166">AASHO. ''[http://www.trafficsign.us/1971mutcd.html Manual for Uniform Traffic Control Devices, 1971 Edition]'', 13 November 1970, pp. 164 & 166</ref>.</blockquote>

Markers on non-freeways were just smaller versions of the freeway ones:

<blockquote>Milepost signs shall be vertical panels with 6-inch white numerals, a border and the word MILE in 4-inch letters on a green background and shall be reflectorized<ref name="1971_mutcd_pp110-111" />.</blockquote>

Three sizes were specified, based on how many numbers would be on the post:

* '''D10-1:''' For 1-digit numbers, 12″ × 24″ on freeways<ref name="1971_mutcd_pp164-166" />, 10″ × 18″ elsewhere<ref name="1971_mutcd_pp110-111" />
* '''D10-2:''' For 2-digit numbers, 12″ × 36″ on freeways<ref name="1971_mutcd_pp164-166" />, 10″ × 27″ elsewhere<ref name="1971_mutcd_pp110-111" />
* '''D10-3:''' For 3-digit numbers, 12″ × 48″ on freeways<ref name="1971_mutcd_pp164-166" />, 10″ × 36″ elsewhere<ref name="1971_mutcd_pp110-111" />

Aside from the size of the numbers and the MILE legend, no typeface suggestions were given. However, the example image in the MUTCD itself appears to use FHWA Gothic Series D for the numerals and Series B for the MILE legend<ref name="1971_mutcd_pp110-111" />.

Oregon mostly adopted the milepost standard as defined in the MUTCD. However, the state opted to use the D10-2 2-digit marker for 1-digit mileposts, with the number vertically centered between MILE and the bottom of the post. This practice was utilized on both freeway and non-freeway routes through the mid-2000s, when ODOT started using the D10-1 marker more frequently for single-digit mileposts. Recently completed transportation projects, like the [[Oregon Route 224|Sunrise Expressway]] and the [[Oregon Route 62|Rogue Valley Expressway]], use D10-1 single-digit panels.

Two of Oregon's first major implementations of the 1971 standard mileposts occurred around early 1972, when the entirety of mileposts on [[Interstate 5|Interstates 5]] and [[Interstate 80N|80N]] were replaced. Interstate 5's mileposts were originally from north to south, but needed to be switched to running south-to-north, per 1961 AASHO standards; Interstate 80N's mileposts were being changed to incorporate increased mileage from the selection of the [[Mount Hood Freeway]] corridor. State Highway Engineer R. L. "Rod" Porter estimated that the cost of revising both highways' milepost systems and installing the new mileposts would cost $25,000 total — $11,500 for I-5 and $13,500 for I-80N — and would need to be done with state forces instead of by several contractors<ref name="1971-12-09_rlporter_letter">Porter, R. L. letter to R. E. Simpson, 9 December 1971, p. 1</ref>.

Technically, just about any milepost on a state highway in Oregon that only includes a border, a MILE legend and large numbers on whole miles is a 1971 specification MUTCD milepost. That said, Oregon does have quite a few subtle variations based primarily on number size and typeface, usually FHWA Series C or D. In addition, later MUTCD specs included variations that Oregon has implemented from time to time.

 

[[File:2003 MUTCD-OR-milepost-examples.png|126px|thumb|right]]
==== 2003 Standards ====

The 1971 MUTCD descriptions for mileposts remained more or less the same for more than 30 years, even after a name change to the more generic "reference posts" in 2000. These standards also allowed for fractional mileposts of some kind, using either delimiters or reference posts at consistent intervals. However, they weren't considered part of the milepost system until 2003, when AASHTO introduced them as "intermediate reference location markers". These mileposts have the same design as the 1971 spec, but with an extra section below the mile number that contains the fractional portion, with decimal (such as ".3")<ref name="2003_mutcd_p2D.27">AASHTO. ''[https://mutcd.fhwa.dot.gov/pdfs/2003/pdf-index.htm Manual for Uniform Traffic Control Devices, 2003 Edition]'', November 2003, p. 2D-27</ref>. The decimal portion is always displayed, even on whole numbers where a ".0" is placed in that section.

The 2003 MUTCD defined sizes for freeway and expressway placement, but not for other highways and roads. Their dimensions are estimated based on the original D10 mileposts of comparable size.

* '''D10-1a:''' For 1-digit numbers – 12″ × 36″ on freeways, 10″ × 27″ elsewhere<ref name="2003_mutcd_p2D.27" />
* '''D10-2a:''' For 2-digit numbers – 12″ × 48″ on freeways, 10″ × 36″ elsewhere<ref name="2003_mutcd_p2D.27" />
* '''D10-3a:''' For 3-digit numbers – 12″ × 60″ on freeways, 10″ × 45″ elsewhere<ref name="2003_mutcd_p2D.27" />

Oregon's first implementation of this standard, however, was not for fractional mileposts. Instead, the mileposts were used to differentiate between sections of [[US Route 395|US-395]] where mileposts reset to zero due to [[Mileposting in Oregon|Oregon's dual highway/route system]]. This resetting confused travelers at best and hindered emergency services at worst, so ODOT decided to add letters in the spot on the post where the fraction would normally reside<ref name="2013_odot_abcs-us395-mile-markers">Oregon Department of Transportation. "The A, B, C's of U.S. 395 Mile Markers in Oregon", 15 August 2013</ref>. ODOT initially added them on two sections in late 2008 or early 2009 — the section of US-395 from Pendleton to Mt. Vernon received "B" while the section from John Day to near Burns received "C"<ref name="eastoreg_2008-11-28">''The East Oregonian.'' "[https://www.eastoregonian.com/news/local/odot-assigns-letters-to-parts-of-highway-395/article_0428f1eb-6ce6-58cb-ae49-4f4ffdc0eefe.html ODOT Assigns Letters to Parts of Highway 395]," 28 November 2008, last updated 13 December 2008, last accessed 23 May 2021</ref>. Letter suffixes "D" and "E" were added to two portions from near Riley to the California border by 2013<ref name="2013_odot_abcs-us395-mile-markers" />; these ones omit the line between the numbers and letter, making them effectively like an original D10 milepost with 4 alphanumerics on them.

The letter suffix system was expanded to [[Oregon Route 207|OR-207]] by early 2018, using "A", "B" and "C" along three different sections<ref name="2018_odot_abcs-mile-markers">Oregon Department of Transportation. "The A, B, C's of Mile Markers in Oregon", 5 January 2018</ref>.

As far as actual fractional mileposts are concerned, their first usage in Oregon was on [[US Route 26|US-26]] between Sandy and the junction of [[Oregon Route 35|OR-35]], installed at half-mile intervals in the summer of 2011 as part of and ODOT pilot project<ref name="sandypost_2011-08-09">Hart, Jim. "New Mile Markers Posted Along Highway 26," ''The Sandy Post'', 9 August 2011</ref>. Since then, Oregon has expanded their usage on other highways to improve response times. Freeway-size D10-2a markers has been installed at half-mile intervals in the median of [[Interstate 84|I-84]] through the Columbia River Gorge, and smaller D10-1a mileposts were installed on the Multnomah County section of then-future [[Oregon Route 127|OR-127]] in the summer of 2019<ref name="multco_cornpass_info">Multnomah County. "Cornelius Pass Road Safety Improvements," last updated 18 December 2020, https://multco.us/roads/webform/cornelius-pass-road-safety-improvements, last accessed 8 February 2021</ref>.

ODOT had placed a D10-2a marker at MP 68.9 along US-26 near Clear Creek in the Mount Hood National Forest in an attempt to avoid the "[[Mile 69 Problem]]". Unfortunately, it was removed by October 2022, likely the result of construction along that segment; as of June 2025, it has not been replaced.

An August 2014 [[Interstate 5|I-5]] optimization study recommended installing half-mile markers between Salem and Albany for incident management and towing purposes<ref name="2014_i5_optimization_ch5p2">DKS Associates. "I-5 Optimization Study, Final Report", August 2014, ch. 5 p. 2.</ref>. However, as of 2024 this has yet to come to fruition. Tenth-mile markers were also considered, but ultimately were not recommended<ref name="2014_i5_optimization_tbl4-3">DKS Associates, table 4-3.</ref>.

[[File:2009 MUTCD-OR-milepost-examples.png|188px|thumb|right]]

==== 2009 Standards ====

The 2009 standard added another milepost type, "enhanced reference location signs", to further aid motorists and emergency responders<ref name="2009_mutcd_p296">AASHTO. ''[https://mutcd.fhwa.dot.gov/pdfs/2009r1r2/pdf_index.htm Manual for Uniform Traffic Control Devices, 2009 Edition with Revisions 1 and 2 Incorporated]'', May 2012, p. 296</ref>. These mileposts contained a cardinal direction, route shield and whole mile number. Two different varieties were defined, one for whole numbers (D10-4) and one for fractional miles (D10-5) which included an extra section below the mileage for the decimal part. Both varieties only came in one size, regardless of mile number or highway type:

* '''D10-4:''' For whole miles only – green or blue, 18″ × 54″<ref name="2009_mutcd_p292">AASHTO. ''[https://mutcd.fhwa.dot.gov/pdfs/2009r1r2/pdf_index.htm Manual for Uniform Traffic Control Devices, 2009 Edition with Revisions 1 and 2 Incorporated]'', May 2012, p. 292</ref>
* '''D10-5:''' For whole and fractional miles – green or blue, 18″ × 60″<ref name="2009_mutcd_p292">AASHTO. ''[https://mutcd.fhwa.dot.gov/pdfs/2009r1r2/pdf_index.htm Manual for Uniform Traffic Control Devices, 2009 Edition with Revisions 1 and 2 Incorporated]'', May 2012, p. 292</ref>

Legends need to be at least 6 inches tall and shields need to be at least 12 inches tall<ref name="2009_mutcd_p296" />. For typefaces on both, the examples in the MUTCD showed the cardinal direction and whole mile number in FHWA Series B, and with "MILE" and the fractional mile (if present) in Series C.

Oregon doesn't use these type of mileposts very often, but they are present in the state. D10-5 markers were installed at half-mile intervals along [[Oregon Route 217|OR-217]] in the summer of 2011 as part of the same pilot project that installed [[Mileposts#2003_Standards|2003-spec D10-2a markers]] along US-26<ref name="sandypost_2011-08-09" />. These markers largely matched those in the MUTCD, but used FHWA Series C for the whole mile number instead of Series B. As of 2021 they do not appear to have been implemented along any other freeway within Oregon.

In addition, D10-4 mileposts can be found in a rare non-freeway instance intermittently along [[US Route 20|US-20]] through the Cascades. Installed around 2016 or 2017, these ones more or less follow the MUTCD example typeface-wise. Some examples can be found at [https://goo.gl/maps/Xgk5D7rPji7196dP7 MP 75], [https://goo.gl/maps/dsUjfaQdqq7KNpwy8 MP 80] and [https://goo.gl/maps/X9cXgQXGwT8bNqki9 MP 83].

[[File:2020s 0mp+ODOT-R3-terminal-mp-example.png|126px|thumb|right]]

=== Terminal Mileposts ===
Oregon initially didn't post any mileposts at a highway's termini, save in the rare instance where a highway ended its mileage at or around the whole mile — one such example is MP 50 at the end [[Oregon Route 224|OR-224]] just across the bridge over the Oak Grove Fork of the Clackamas River. Prior to 2000, "BEGIN" and "END" banners were not present on state highways in Oregon at either terminus. For unsigned state routes that continued beyond the end of state maintenance, the change in jurisdiction (if indicated at all) was either indicated by an "END STATE HIGHWAY MAINTENANCE" sign or some sort of county signage indicating the start of their maintenance. The new millennium ushered in a few "END" shield assemblies on some signed state routes, and even a "BEGIN" assembly or two (such as the "BEGIN [[US Route 20|US-20]]" assembly at its western terminus, [[US Route 101|US-101]] in Newport).

At the tail end of the 2010s, Oregon started experimenting with terminal mileposts in different parts of the state. Along the [[Interstate 5|I-5]] corridor, ODOT posted D10-2 zero mileposts along two intersecting signed state highways: At the northern terminus of [[Oregon Route 551|OR-551]] and at the junction of I-5 and [[Oregon Route 99E Business (Salem)|OR-99E Business]] in Keizer. These are possibly the first zero mileposts along a state-maintained highway in Oregon. The "0" numeral (in what looks to be FHWA Series D) is considerably larger than numerals used in standard D10-2 mile markers.

In addition, by June 2021 ODOT Region 3 had marked the ends of some of its unsigned/poorly-signed state maintained highways with distinctive panels. The words "END ODOT" would be stacked on top, followed by the ODOT logo, then "MP" over the terminal milepost number to two decimal spots (or "0.0" at the zero milepoint), and finally the name of the highway over "HWY. ###" — with "###" being the state ''highway'' number, not the state ''route'' number. So far they have been observed at termini on highways in both Coos and Curry County: [[Oregon Route 241|OR-241]], [[Oregon Route 542|OR-542]], [[Oregon Route 250|OR-250]], and [[Oregon Route 251|OR-251]]<ref name="aaroads_2021-06-29">Chris [xonhulu].

</gallery>

=== Miscellany ===

* Rarely, some mileposts will have a "Z" above the number, such as on a section of [[US Route 101|US-101]] near Wheeler. This is due to a highway realignment or cancellation and is used to denote duplicate mileposts along a highway, and is similar to "B"-mileage in Washington or "R"-mileage in California. For additional information on Oregon's milepoint system, see [[Mileposting in Oregon]].

 

== County Roads ==

[[File:Mp-county-clackamas-examples.png|180px|thumb]]
=== Clackamas County ===

Three different kinds of mileposts can be found on Clackamas County roads:

* Green MUTCD D10-2 mileposts for 1- and 2-digit numbers, marked at whole miles
* White metallic rounded rectangles, marked at culverts in hundredths of a mile
* White delineator wickets embedded in the ground, also marked at culverts in hundredths of a mile

Each of these mileposts contains the mileage — whole numbers on green mileposts, tenths or hundredths of a mile on white ones — and a 5-digit county road number. This number can sometimes span two different roads if they comprise a longer route, such as Stafford and Wilsonville Roads.

The green mileposts used to be more prevalent in the 1990s but have been disappearing as they're damaged or otherwise removed. The white markers are much more prominent, but can be more hidden and sometimes don't face traffic.

At jurisdictional boundaries, the white markers can also sometimes be found with "BCM" and "ECM", for "begin county maintenance" and "end county maintenance" respectively, depending on the direction of travel. On the wickets, no other information (such as mileposts or road numbers) are present; the metal rectangle versions of these posts ''can'' contain the road number, but again no mileage is indicated.

Zero mileposts can be found among all three types, though the green ones are much rarer.

=== Clatsop County ===

Prior to the mid 2010s, mileposts on Clatsop County roads appeared only on green wickets placed in the vicinity of a culvert. These wickets show the mileage in tenths, hundredths, or even ''thousandths'' of a mile, without identifying any sort of road name or number. The typeface used is a thinner stroke version of Helvetica Inserat Roman.

In early 2015, some roads were provided with mileposts in three new distinct styles, leaving the green wickets intact:

* A standard D10-1 or D10-2 milepost, mounted on a post in the center with numbers in FHWA Series C or D. Some enhancements have also been added:
** The 2-digit year of manufacture or installation is in black in the upper right
** The road name and number are in white on the bottom towards the left
** "Clatsop County" is in black on the lower right
** The month and year of installation may be written in permanent marker somewhere on the milepost
* A different D10-1 (and possibly D10-2) milepost, mounted on a post to the ''side''; in addition, the 2-digit year, "Clatsop County" stamp and written installation date are omitted. On these markers, the numbers are in FHWA Series B.
* A white wicket with a green sticker stating "MILE" and the mile number. All letters and numbers are in condensed FHWA Series C.

Other variations may also exist, but have yet to be discovered or documented.

In addition, [[Bridge and Culvert Inventory Markers#Clatsop County|inventory markers placed on county bridges]] display the milepoint number alongside other bridge information.

[[File:Mp-county-columbia-examples.png|126px|thumb]]

=== Columbia County ===

Columbia County does not place mileposts along all of its roads, but does on some major ones like Apiary Road and Scappoose-Vernonia Highway. When they are placed, they are standard D10-1 and D10-2 mileposts with the numeral in FHWA Series D. No other markings or information appears to be on the signs themselves.

 

[[File:Mp-county-coos.png|60px|thumb]]
=== Coos County ===

Coos County has used their own version of an "enhanced" milepost for at least 20 years, though overall it appears more in line with the 1961 MUTCD spec. It consists of a simple green rectangle 6″ × 18″ with no border or "MILE" legend, with a FHWA Series C numeral roughly centered at the top of the sign. Below the numeral is a square sticker of a Coos County reassurance shield with the road number placed inside. The road number is also in Series C, but the "COOS COUNTY" inside the shield appears to be different weights of Helvetica Neue LT Pro; "COOS" is in 87 Heavy Condensed and "COUNTY" is either 77 Bold Condensed or 67 Medium Condensed.

 

[[File:Mp-county-douglas-examples.png|192px|thumb]]
=== Douglas County ===

Douglas County places its mileposts at mile intervals along many of its county roads, using two distinct styles:

* The first style is similar to the state's 1961 MUTCD spec marker, except it's smaller, shorter and uses Series E(M) for its numerals instead of Series E.
* The second, much more common style follows the 1971 MUTCD spec, using a D10-2 for 1-digit mileages and a D10-3 for 2-digit mileage, using Series B, C or D.

Both mileposts leave a space below the numeral for a sticker or decal of a Douglas County reassurance shield with the road number placed inside, similar to Coos County. However, Douglas County's shields have a yellow background and are entirely in FHWA Gothic fonts; Coos County's shields have a white background, and some of the text is in Helvetica Neue LT Pro.

 

[[File:Mp-county-hoodriver-examples.png|258px|thumb]]
=== Hood River County ===

Hood River County mileposts its roads using a simple green panel with "MP" at the top and the number below it. The same size panel appears to be used for 1- and 2-digit numbers. Mileposts appear to be placed on the side of the road where mileage increases, with a mile marker facing each direction of travel. All characters appear to be in FHWA Series C.

There does appear to be some sort of hundredths marker that the county uses. Similar to other county mile markers, it is topped with "MP", but displays the two hundredths-mileage digits below the integer mile in smaller numbering, making these markers taller than the others. A version with black text on a white background can be found on [https://maps.app.goo.gl/4MWtnMQJc1Jsirk2A Baseline Drive at MP 0.46], likely indicating a culvert or creek crossover. Until roughly 2021, a version with white text on a green background could be seen on Forest Lane at the I-84 overpass in Cascade Locks, where the road becomes state-maintained. The text "F4 END" was placed on the back of the marker down the right side; while "END" signified the jurisdictional changeover, it is currently unknown what "F4" stands for. It is also unknown if any other of these hundredths markers have text on their backs. (The Forest Lane marker was removed around 2021 due to bridge and freeway construction. It was replaced, possibly by ODOT, with another milepost which erroneously displays "MP 8".)

=== Linn County ===

Linn County doesn't appear to place mileposts along its county roads. However, it does place [[Bridge and Culvert Inventory Markers#Linn County|inventory markers on bridges]] that displays the milepoint alongside other information.

 

[[File:Mp-county-marion-examples.png|60px|thumb]]

=== Marion County ===

Marion County doesn't regularly place mileposts along its county roads. However, an old-looking MP 5 marker was rediscovered on Cascade Hwy SE just south of its junction with [[Oregon Route 214|OR-214]] as of June 2019. It was present at that location prior to October 2008 and was likely placed within the past 30-40 years, but has since been knocked at an angle. The marker is a standard D10-1 milepost with the numeral in FHWA Series C. The northbound (south-facing) side is much more deteriorated than the southbound (north-facing) side.

Additional research is needed to determine if any more markers exist along Marion County backroads.

[[File:Mp-county-multnomah-examples.png|126px|thumb]]

=== Multnomah County ===

Multnomah County has used standard D10-1 and D10-2 mileposts along its roads since at least the mid-1980s, though they used to be more common than they are now. The large numerals are usually in FHWA Series C, but can also be found in Series D. They are commonly mounted on wooden posts with the top carved into a point, a typical feature of Multnomah County signage.

The county did place D10-1a mileposts at half-mile intervals along [[Oregon Route 127|Cornelius Pass Road]] in 2019, but this was likely done in conjunction with ODOT in preparation to turn it over to state jurisdiction. Multnomah County milepost 5 was confirmed on Cornelius Pass Road at the Washington County line as of May 28, 2021, but was removed by January 2022.

[[File:Mp-county-tillamook-examples.png|270px|thumb]]

=== Tillamook County ===

{{See|article=[[Bridge and Culvert Inventory Markers#Tillamook County|Bridge and Culvert Inventory Markers: Tillamook County]]}}

Prior to about 2015, Tillamook County largely used standard D10-1 and D10-2 mileposts along many of its county roads, with numbers typically using FHWA Series D. In some instances, a D10-1 milepost may have two digits; in other instances, a D10-2 milepost may have one digit. Some D10-2 mileposts had a thicker border and more space between the "MILE" legend and the numbers; the numbers themselves may also use a different FHWA Series, like Series C.

Around 2015, a new variety of milepost started appearing along some county roads, such as Foss Road and Fairview Road. These mileposts were more squarish in appearance with a much thicker white border around them, a much more reflective green background, and one or two digits inside. The numbers are FHWA Series B stretched about 30% wider than usual.

In addition, a smaller third type of milepost has been found on Gods Valley Road at MP 3. This milepost is roughly 6″ × 15″ with a thick white border and uses FHWA Series B in both the "MILE" legend and the number. Whether this type of marker is used on other county roads is unknown at this time.

[[File:Mp-county-umatilla-examples.png|126px|thumb]]

=== Umatilla County ===

Umatilla County appears to place D10-1 and D10-2 mileposts along many of its county roads. The designs are slightly modified from the standard to place "UMATILLA COUNTY" in small FHWA Series C text centered below the numeral on two separate lines, but are otherwise the same as other 1971 MUTCD spec mileposts. No other road information appears to be present on these signs.

 

=== Wasco County ===

Wasco County doesn't appear to place mileposts along its county roads.

[[File:Mp-county-washington.png|60px|thumb]]
=== Washington County ===

{{See|article=[[Bridge and Culvert Inventory Markers#Washington County|Bridge and Culvert Inventory Markers: Washington County]]}}

Mileposts along Washington County roads are pretty rare and usually aren't present at all. When they are, they are simple green rectangles 6″ × 18″ with no border, with "MP" and the number in the same size FHWA Series B typeface. They are usually — though not always — accompanied by a smaller green rectangle 6″ × 10″ with a thin white border bearing the text "WASHINGTON COUNTY ROAD" and the road number, both also in Series B. Due to their weathered appearance in the wild, it's likely these mileposts were placed more than 30 years ago. Only a handful are known to have survived into the 2010s:

{| class="wikitable"

|-

|}

Others may still exist along Washington County backroads.

Older state mileposts can also be found on sections of state routes turned back over to county jurisdiction. 1961 MUTCD specification posts are present as of 2021 at MP 2 and 3 along [[Oregon Route 210|OR-210/Scholls Ferry Road]]; MP 4 near Kinton was present until the mid-2010s. A 1971 spec MP 12 also exists at the north end of Scholls Ferry Road near [[Oregon Route 10|OR-10/Beaverton Hillsdale Highway]]. On [[Oregon Route 10|OR-10/Farmington Road]], a 1971 spec MP 3 was present eastbound as of August 2018; a 1961 spec milepost at that same location westbound was removed sometime after 2002, and other 1971 spec mileposts were removed over a 10-15 year period after that section of OR-10 was relinquished to the county.

Curiously, Washington County placed a D10-1 standard "MILE 1" marker on Scholls Ferry Road in Scholls at milepoint 1 of the old Scholls Highway #143 when the Tualatin River bridge was rebuilt in 2008. These markers — possibly the only MUTCD standard mileposts placed by Washington County — replaced a 1971 spec marker eastbound and a 1961 spec marker westbound.

=== Yamhill County ===

Yamhill County doesn't appear to place mileposts along its county roads.

== Other Jurisdictions ==

=== Native Reservations ===

[[File:Mp-bia-warmsprings-examples.png|258px|thumb]]
==== Warm Springs Reservation ====

Mileposts have been observed along [[Bureau of Indian Affairs Road 3 (Warm Springs Reservation)|BIA-3]] and [[Bureau of Indian Affairs Road 9 (Warm Springs Reservation)|BIA-9]] inside the reservation. They are standard green 1971 D10-1 and D10-2 mileposts, with numerals usually in FHWA Series C. Some variants have been seen, such as using FHWA Series D numerals or using a D10-2 milepost for a single-digit milepoint. Other styles may exist on other BIA roads.

Mileposts appear only to be posted in the direction of increasing mileage, when they are posted at all.

=== National Forests ===

It is unknown at this time if all National Forests in Oregon use mileposts on their roads. However, these ones have been observed:

[[File:Mp-nf-mthood-examples.png|97px|thumb]]
==== Mount Hood National Forest ====

So far, two types of mileposts have been observed along National Forest primary routes in the Mount Hood National Forest. The older type is a simple brown wicket with "MP" across the top and a larger mile number below. All text is in FHWA Series C. If the mile number is larger than 9, the number itself is stacked like a standard milepost. These mileposts have been observed on both [[National Forest Highway 44 (Mount Hood National Forest)|National Forest 44]] and [[National Forest Highway 46 (Mount Hood National Forest)|National Forest 46]]. Varieties found on [[National Forest Highway 43 (Mount Hood National Forest)|National Forest 43]] use stickers for the "MP" in an as-yet-unidentified heavyweight sans-serif font (likely in the Helvetica family), with the number in FHWA Series B. Additionally, mileposts on [[National Forest Highway 42 (Mount Hood National Forest)|National Forest 42]] entirely use stickers featuring that same unidentified font.

In January 2025, a newer milepost design was observed along [[National Forest Highway 57 (Mount Hood National Forest)|National Forest 57]] east of its junction with National Forest 44 and [[Oregon Route 224|Oregon 224]]. This type also uses a brown wicket, but has the word "MILE" on top in small FHWA Series E, the mile number below that in FHWA Series C, and a tiny route number at the bottom in FHWA Series B. The route number is in the format "NFxx", where "xx" is replaced by the route number (e.g., "NF57"). It is unknown if the mile number is stacked when greater than 9. As the area around National Forest 57 was heavily damaged by the Riverside Fire in September 2020, it is theorized that these mileposts were installed sometime afterwards.

No mileposts were observed along [[National Forest Highway 48 (Mount Hood National Forest)|National Forest 48]] between National Forest 43 and [[Oregon Route 35|Oregon 35]] in July 2025.

It is unknown at this time if mileposts exist on National Forest primary routes apart from National Forest 42, 43, 44, 46 and 57, or if they appear on secondary or tertiary forest roads and trials. It is also unknown at this time if the newer milepost design will be applied to other primary routes within the forest.

=== State Forest and Timber Lands ===

It is unknown at this time if all state forests in Oregon use mileposts on their roads. However, these ones have been observed:

[[File:Mp-sf-clatsop-examples.png|160px|thumb]]
==== Clatsop State Forest ====

Some roads within the Tillamook State Forest have mileposts, usually nailed to a tree. They are yellow rectangular signs with a large black mile number centered on the sign. The number is usually in Helvetica Inserat, but other fonts like Franklin Gothic Heavy may be used. The signs don't contain any other information that identifies the road.

Most likely, these mileposts are placed by the Oregon Department of Forestry to aid both recreational vehicles and logging trucks. They are usually placed at half-mile intervals, but can sometimes go missing. Usually, mileposts are posted in pairs so as to be seen in both directions of travel.

On occasion, the milepost will be surrounded by spray paint on the tree to improve visibility.

Unlike other jurisdictions, fractional mileposts use vulgar fractions (e.g., ½) instead of decimal fractions (e.g., 0.5). The vulgar fraction portion appears to be in a condensed version of Helvetica in medium weight.

[[File:Mp-sf-tillamook-examples.png|111px|thumb]]
==== Tillamook State Forest ====

Some roads within the Tillamook State Forest have mileposts, usually nailed to a tree. They are yellow rectangular signs with a large black mile number centered on the sign. The number is usually in Helvetica or a typeface similar to Frutiger or Calibri, but other fonts may be used. The signs don't contain any other information that identifies the road.

As the mileposts persist on roads that leave State Forest lands, it is unknown who places the mileposts along these roads. Most likely, they are placed by the Oregon Department of Forestry to aid both recreational vehicles and logging trucks. They are usually placed at half-mile intervals, but can sometimes go missing. Usually, mileposts are posted in pairs so as to be seen in both directions of travel.

On occasion, the milepost will be spray-painted on a tree instead of using a sign.

Jonathan: Added more articles

[[File:2020-04-12 i5-nb-exit-286-night 6958.jpg|350px|thumb|right]]
'''Welcome to Beaver State Roads!'''

My name is Jonathan. Simply put, Beaver State Roads aims to be your one-stop shop for information on Oregon state routes, highways, and other important roads. It was borne out of an earlier project, [http://oroads.beaverstateroads.org ORoads], which was originally hosted on Angelfire starting around 2002 under my pseudonym ''Jason of ORoads''. Unfortunately, ORoads became all but abandonned in the late 2000s-early 2010s due to life and other things, and during that time both the site design and the information within grew stale. Beaver State Roads strives to correct the outdated information plus add in the wealth of additional knowledge obtained over the past 20 years, presenting route and highway history and data as accurate as possible.

== 📄 Pages ==
While I'll be adding more pages to the site in the future, here's what's available now:

* Pages on Oregon state routes:
** [[Oregon Route 2]] 🚧, what is now US-26 from Cannon Beach Junction to Portland
** [[Oregon Route 37]], created in 1972
** [[Oregon Route 42N]], rediscovered thanks to [https://www.aaroads.com/forum/index.php?topic=18931.0 a 2016 AARoads post]
** [[Oregon Route 64]] — yes, you read that right — an extremely short-lived state route which became a westward extension of Oregon Route 140
** [[Oregon Route 127]], applied to Cornelius Pass Road between Burlington and Hillsboro in 2020
** [[Oregon Route 132]], applied to the Delta Highway within Eugene in 2019
** The second (and current) iteration of [[Oregon Route 224]] 🚧, created c.1961
** The first iteration of [[Oregon Route 231 (Oswego-Wilsonville)|Oregon Route 231]] from Oswego to Wilsonville, which may have only existed on paper around 1934
** [[US Route 320]], proposed to — and soundly rejected by — AASHO in 1958, rediscovered thanks to [https://groups.google.com/g/misc.transport.road/c/xaZ3k8VXwRI#ae67e67c372e78a3 a 2005 misc.transport.road post]
** [[US Route 730]] 🚧, currently both America's highest-numbered and shortest-length US route, defined in 1926
* Articles on mileposting and related signage:
** [[Mileposts]]
*** A [[List of Surviving Concrete Mileposts|list of surviving concrete mileposts]] originally erected starting in 1924
** [[Bridge and Culvert Inventory Markers]]
** The [[Mile 69 Problem|"Mile 69 Problem"]]
* A page of [[Common Abbreviations|common abbreviations]] used on the site

Future articles will revolve around [[Oregon Route 6]] and [[Mileposting in Oregon|Oregon's mileposting system as a whole]].

== ❓ How to Help ==

At present, writing these articles is a solo effort. Once I get some good information on here in the near future, the goal is to recruit additional Oregon roadgeeks as contributors. The decision to present this site in a wiki format was made with collaboration and education in mind. I don't have all the answers, and want to give people who may have those answers a platform on which to reveal them. Once I figure out some basic guidelines, I will extend offers as necessary.

However, there are other ways to help:

* What I prize above all is '''information'''. This includes (but isn't limited to) any documents, photos, maps, articles, meeting minutes, or other miscellany that may shed new light on Oregon's highways or provide a glimpse into the past, present or future. If you have anything about Oregon's highways that I can use on this site — especially historic or unique photos — please feel free to send it to '''beaverstateroads''' ''AT'' '''gmail''' ''DOT'' '''com'''. You will be given credit on the [[Beaver_State_Roads:About|about page]] once I write it.
* That said, I will eventually figure out how to set up accounts for people to '''donate''' to assist the site. This is necessary because unfortunately, a lot of good information, including high-quality photos, are locked away behind expensive fees to retrieve and scan the data. For example, the Oregon Secretary of State's office demands $20 per high-quality scan of photos, and research time in the Multnomah County archives can add up quickly. Any future financial assistance I receive would be much appreciated, and I would make an effort to document where and how the money I receive is used.
* I may also need some assistance making this site '''mobile-friendly''' in the near future.

Creating the most complete history of Oregon state highways is a herculean effort, but with your help it doesn't have to be. Thank you in advance!

Jonathan: Removed icon

[[File:2020-04-12 i5-nb-exit-286-night 6958.jpg|350px|thumb|right]]
'''Welcome to Beaver State Roads!'''

My name is Jonathan. Simply put, Beaver State Roads aims to be your one-stop shop for information on Oregon state routes, highways, and other important roads. It was borne out of an earlier project, [http://oroads.beaverstateroads.org ORoads], which was originally hosted on Angelfire starting around 2002 under my pseudonym ''Jason of ORoads''. Unfortunately, ORoads became all but abandonned in the late 2000s-early 2010s due to life and other things, and during that time both the site design and the information within grew stale. Beaver State Roads strives to correct the outdated information plus add in the wealth of additional knowledge obtained over the past 20 years, presenting route and highway history and data as accurate as possible.

== 📄 Pages ==
While I'll be adding more pages to the site in the future, here's what's available now:

* Pages on Oregon state routes:
** [[Oregon Route 2]] 🚧, what is now US-26 from Cannon Beach Junction to Portland
** [[Oregon Route 37]], created in 1972
** [[Oregon Route 42N]], rediscovered thanks to [https://www.aaroads.com/forum/index.php?topic=18931.0 a 2016 AARoads post]
** [[Oregon Route 64]] — yes, you read that right — an extremely short-lived state route which became a westward extension of Oregon Route 140
** [[Oregon Route 127]], applied to Cornelius Pass Road between Burlington and Hillsboro in 2020
** [[Oregon Route 132]], applied to the Delta Highway within Eugene in 2019
** The second (and current) iteration of [[Oregon Route 224]] 🚧, created c.1961
** The first iteration of [[Oregon Route 231 (Oswego-Wilsonville)|Oregon Route 231]] from Oswego to Wilsonville, which may have only existed on paper around 1934
** [[US Route 320]], proposed to — and soundly rejected by — AASHO in 1958, rediscovered thanks to [https://groups.google.com/g/misc.transport.road/c/xaZ3k8VXwRI#ae67e67c372e78a3 a 2005 misc.transport.road post]
** [[US Route 730]] 🚧, currently both America's highest-numbered and shortest-length US route, defined in 1926
* Articles on mileposting and related signage:
** [[Mileposts]]
*** A [[List of Surviving Concrete Mileposts|list of surviving concrete mileposts]] originally erected starting in 1924
** [[Bridge and Culvert Inventory Markers]]
** The [[Mile 69 Problem|"Mile 69 Problem"]]
* A page of [[Common Abbreviations|common abbreviations]] used on the site

Future articles will revolve around [[Oregon Route 6]] and [[Mileposting in Oregon|Oregon's mileposting system as a whole]].

== ❓ How to Help ==

At present, writing these articles is a solo effort. Once I get some good information on here in the near future, the goal is to recruit additional Oregon roadgeeks as contributors. The decision to present this site in a wiki format was made with collaboration and education in mind. I don't have all the answers, and want to give people who may have those answers a platform on which to reveal them. Once I figure out some basic guidelines, I will extend offers as necessary.

However, there are other ways to help:

* What I prize above all is '''information'''. This includes (but isn't limited to) any documents, photos, maps, articles, meeting minutes, or other miscellany that may shed new light on Oregon's highways or provide a glimpse into the past, present or future. If you have anything about Oregon's highways that I can use on this site — especially historic or unique photos — please feel free to send it to '''beaverstateroads''' ''AT'' '''gmail''' ''DOT'' '''com'''. You will be given credit on the [[Beaver_State_Roads:About|about page]] once I write it.
* That said, I will eventually figure out how to set up accounts for people to '''donate''' to assist the site. This is necessary because unfortunately, a lot of good information, including high-quality photos, are locked away behind expensive fees to retrieve and scan the data. For example, the Oregon Secretary of State's office demands $20 per high-quality scan of photos, and research time in the Multnomah County archives can add up quickly. Any future financial assistance I receive would be much appreciated, and I would make an effort to document where and how the money I receive is used.
* I may also need some assistance making this site '''mobile-friendly''' in the near future.

Creating the most complete history of Oregon state highways is a herculean effort, but with your help it doesn't have to be. Thank you in advance!

Jonathan: Added more articles to main page

[[File:2020-04-12 i5-nb-exit-286-night 6958.jpg|350px|thumb|right]]
'''Welcome to Beaver State Roads!'''

My name is Jonathan. Simply put, Beaver State Roads aims to be your one-stop shop for information on Oregon state routes, highways, and other important roads. It was borne out of an earlier project, [http://oroads.beaverstateroads.org ORoads], which was originally hosted on Angelfire starting around 2002 under my pseudonym ''Jason of ORoads''. Unfortunately, ORoads became all but abandonned in the late 2000s-early 2010s due to life and other things, and during that time both the site design and the information within grew stale. Beaver State Roads strives to correct the outdated information plus add in the wealth of additional knowledge obtained over the past 20 years, presenting route and highway history and data as accurate as possible.

== 📄 Pages ==
While I'll be adding more pages to the site in the future, here's what's available now:

* Pages on Oregon state routes:
** [[Oregon Route 2]] 🚧, what is now US-26 from Cannon Beach Junction to Portland
** [[Oregon Route 37]], created in 1972
** [[Oregon Route 42N]], rediscovered thanks to [https://www.aaroads.com/forum/index.php?topic=18931.0 a 2016 AARoads post]
** [[Oregon Route 64]] — yes, you read that right — an extremely short-lived state route which became a westward extension of Oregon Route 140
** [[Oregon Route 127]], applied to Cornelius Pass Road between Burlington and Hillsboro in 2020
** [[Oregon Route 132]], applied to the Delta Highway within Eugene in 2019
** The second (and current) iteration of [[Oregon Route 224]] 🚧, created c.1961
** The first iteration of [[Oregon Route 231 (Oswego-Wilsonville)|Oregon Route 231]] from Oswego to Wilsonville, which may have only existed on paper around 1934
** [[US Route 320]], proposed to — and soundly rejected by — AASHO in 1958, rediscovered thanks to [https://groups.google.com/g/misc.transport.road/c/xaZ3k8VXwRI#ae67e67c372e78a3 a 2005 misc.transport.road post]
** [[US Route 730]] 🚧, currently both America's highest-numbered and shortest-length US route, defined in 1926
* Articles on mileposting and related signage:
** [[Mileposts]]
*** A [[List of Surviving Concrete Mileposts|list of surviving concrete mileposts]] originally erected starting in 1924
** [[Bridge and Culvert Inventory Markers]]
** The [[Mile 69 Problem|"Mile 69 Problem"]]
* A page of [[Common Abbreviations|common abbreviations]] used on the site

Future articles will revolve around [[Oregon Route 6]] and [[Mileposting in Oregon|Oregon's mileposting system as a whole]].

== ❓ How to Help ==

At present, writing these articles is a solo effort. Once I get some good information on here in the near future, the goal is to recruit additional Oregon roadgeeks as contributors. The decision to present this site in a wiki format was made with collaboration and education in mind. I don't have all the answers, and want to give people who may have those answers a platform on which to reveal them. Once I figure out some basic guidelines, I will extend offers as necessary.

However, there are other ways to help:

* What I prize above all is '''information'''. This includes (but isn't limited to) any documents, photos, maps, articles, meeting minutes, or other miscellany that may shed new light on Oregon's highways or provide a glimpse into the past, present or future. If you have anything about Oregon's highways that I can use on this site — especially historic or unique photos — please feel free to send it to '''beaverstateroads''' ''AT'' '''gmail''' ''DOT'' '''com'''. You will be given credit on the [[Beaver_State_Roads:About|about page]] once I write it.
* That said, I will eventually figure out how to set up accounts for people to '''donate''' to assist the site. This is necessary because unfortunately, a lot of good information, including high-quality photos, are locked away behind expensive fees to retrieve and scan the data. For example, the Oregon Secretary of State's office demands $20 per high-quality scan of photos, and research time in the Multnomah County archives can add up quickly. Any future financial assistance I receive would be much appreciated, and I would make an effort to document where and how the money I receive is used.
* I may also need some assistance making this site '''mobile-friendly''' in the near future.

Creating the most complete history of Oregon state highways is a herculean effort, but with your help it doesn't have to be. Thank you in advance!

'''Welcome to Beaver State Roads!'''

My name is Jonathan. Simply put, Beaver State Roads aims to be your one-stop shop for information on Oregon state routes, highways, and other important roads. It was borne out of an earlier project, [http://oroads.beaverstateroads.org ORoads], which was originally hosted on Angelfire starting around 2002 under my pseudonym ''Jason of ORoads''. Unfortunately, ORoads became all but abandonned in the late 2000s-early 2010s due to life and other things, and during that time both the site design and the information within grew stale. Beaver State Roads strives to correct the outdated information plus add in the wealth of additional knowledge obtained over the past 20 years, presenting route and highway history and data as accurate as possible.

== 📄 Pages ==
While I'll be adding more pages to the site in the future, here's what's available now:

* Pages on Oregon state routes:
** [[Oregon Route 2]] 🚧, what is now US-26 from Cannon Beach Junction to Portland
** [[Oregon Route 37]], created in 1972
** [[Oregon Route 42N]], rediscovered thanks to [https://www.aaroads.com/forum/index.php?topic=18931.0 a 2016 AARoads post]
** [[Oregon Route 64]] — yes, you read that right — an extremely short-lived state route which became a westward extension of Oregon Route 140
** [[Oregon Route 127]], applied to Cornelius Pass Road between Burlington and Hillsboro in 2020
** [[Oregon Route 132]], applied to the Delta Highway within Eugene in 2019
** The second (and current) iteration of [[Oregon Route 224]] 🚧, created c.1961
** The first iteration of [[Oregon Route 231 (Oswego-Wilsonville)|Oregon Route 231]] from Oswego to Wilsonville, which may have only existed on paper around 1934
** [[US Route 320]], proposed to — and soundly rejected by — AASHO in 1958, rediscovered thanks to [https://groups.google.com/g/misc.transport.road/c/xaZ3k8VXwRI#ae67e67c372e78a3 a 2005 misc.transport.road post]
** [[US Route 730]] 🚧, currently both America's highest-numbered and shortest-length US route, defined in 1926
* Articles on mileposting and related signage:
** [[Mileposts]]
*** A [[List of Surviving Concrete Mileposts|list of surviving concrete mileposts]] originally erected starting in 1924
** [[Bridge and Culvert Inventory Markers]]
** The [[Mile 69 Problem|"Mile 69 Problem"]]
* A page of [[Common Abbreviations|common abbreviations]] used on the site

Future articles will revolve around [[Oregon Route 6]] and [[Mileposting in Oregon|Oregon's mileposting system as a whole]].

== ❓ How to Help ==

At present, writing these articles is a solo effort. Once I get some good information on here in the near future, the goal is to recruit additional Oregon roadgeeks as contributors. The decision to present this site in a wiki format was made with collaboration and education in mind. I don't have all the answers, and want to give people who may have those answers a platform on which to reveal them. Once I figure out some basic guidelines, I will extend offers as necessary.

However, there are other ways to help:

* What I prize above all is '''information'''. This includes (but isn't limited to) any documents, photos, maps, articles, meeting minutes, or other miscellany that may shed new light on Oregon's highways or provide a glimpse into the past, present or future. If you have anything about Oregon's highways that I can use on this site — especially historic or unique photos — please feel free to send it to '''beaverstateroads''' ''AT'' '''gmail''' ''DOT'' '''com'''. You will be given credit on the [[Beaver_State_Roads:About|about page]] once I write it.
* That said, I will eventually figure out how to set up accounts for people to '''donate''' to assist the site. This is necessary because unfortunately, a lot of good information, including high-quality photos, are locked away behind expensive fees to retrieve and scan the data. For example, the Oregon Secretary of State's office demands $20 per high-quality scan of photos, and research time in the Multnomah County archives can add up quickly. Any future financial assistance I receive would be much appreciated, and I would make an effort to document where and how the money I receive is used.
* I may also need some assistance making this site '''mobile-friendly''' in the near future.

Creating the most complete history of Oregon state highways is a herculean effort, but with your help it doesn't have to be. Thank you in advance!

Bridge and Culvert Inventory Markers

2025-11-19T00:36:36Z

Jonathan: Added photos and supplemental information on Beaverton bridge markers

'''Bridge and Culvert Inventory Markers''' are signs that identify bridges and culverts for jurisdictional maintenance purposes and occasionally to assist the travelling public. Oregon has placed inventory markers on bridges since around the year 2000, but some counties and cities have used them in decades prior.

== State Highways ==
[[File:Odot-bridge-inventory-marker-examples.png|258px|thumb]]
=== Bridge Inventory Markers ===

By 2001, ODOT started placing standardized inventory markers at some bridges and overpasses. ODOT's logo is at the top, with a phone number underneath it. Information about the bridge — route number, highway number, milepoint, and ODOT bridge number — is placed in the middle, with the name of the feature being crossed below that. Variations do exist, likely as a result of the contractors used on various projects:

* The "ODOT" in the ODOT logo used to be in Helvetica, but has changed typeface in recent years. All other text is in FHWA Series B, though often times it is condensed even more to fit additional information.
* Phone numbers change depending on the location of the marker and are included as a public safety service. Numbers currently documented include:
** 503-378-2299: 24/7 ODOT Dispatch Center
** 503-283-5859: ODOT Region 1 (Portland Metro Area) Dispatch Center
** 503-362-0457: ODOT Region 2 (NW Oregon) Dispatch Center
** 541-296-2215: ODOT Maintenance District 9 (The Dalles)
* Phone numbers sometimes have dashes in between them.
* Some markers display the text "EMERGENCY ONLY" below the phone number in Series D.
* Interstate routes are displayed with an "I-" in front of the number; by comparison, US and state routes are usually not prefixed by "US" or "OR".
* Milepoints are usually to two decimal points, though some markers exist with only a single decimal point.
* All letters on the markers used to be in all caps; however, the intersecting feature text can sometimes be found in mixed case, such as in markers along the [[Oregon Route 18|Newberg-Dundee Bypass]].
* The text in the intersecting feature section is usually centered, but can sometimes also be left-aligned.
* Milepoints can be negative. If this is the case, they will be displayed with a minus sign in front of the milepoint (e.g. MP -0.52). Negative mileage used to be known as "X-mileage", though there are no known inventory markers that use an "X" instead of a "-".

While many of ODOT's inventory markers legibly display correct information, quite a few do not:

* Some markers place the highway number in the "RTE" section and vice versa – for example, the marker at Mills Bridge on [[Oregon Route 6|OR-6]] displays Route 37 and Highway #6
* Some markers display the wrong route number – for example, the marker on [[Oregon Route 202|OR-202]] across Beneke Creek erroneously displays [[Oregon Route 47|OR-47]] in the "RTE" section
* Some markers on unsigned or formerly-unsigned state routes place the route number in the "RTE" section, but place a condensed abbreviation of the highway name in "HWY" – for example, markers on [[Oregon Route 103|OR-103]] display "Fishhawk F" in illegibly-small condensed Type B
* Some markers display a non-existent route – for example, markers on [[Oregon Route 194|OR-194]] erroneously state they are on "US-51"
* Some markers display redundant information – for example, some markers on OR-18 display the highway number and/or milepoint inside the intersecting feature section in addition to their usual spots

[[File:Odot-culvert-marker-examples.png|230px|thumb]]

=== Culvert and Stormwater Facility Markers ===

Around 2013, ODOT started placing standardized markers at culverts and stormwater facilities. For culverts, two types of markers are defined in [https://www.oregon.gov/odot/engineering/202207/RD398.pdf ODOT Standard Drawing RD398], aptly named Type 1 and Type 2.

* '''Type 1''' markers are 4″ × 6–12″ strips of green thermoplastic tape affixed to the road, with no other information added.
* '''Type 2''' markers are 3½″ × 13¼″ white panels with a green stripe at the top. "ODOT" appears above the stripe. A number appears below the stripe — either the Drainage Facility ID (or "DFI number") if the culvert span is less than 6 feet, or the Bridge Structure ID if the culvert span is between 6 and 20 feet. Below the number is the culvert milepoint. All text on the marker is FHWA Series C, called "Type C font" in the drawing.

Stormwater facilities have three types of markers defined in [https://www.oregon.gov/odot/engineering/202207/RD399.pdf ODOT Standard Drawing RD399], named Type S1, S2 and S3.

* '''Type S1''' markers are flexible plastic posts embedded into the ground in two colors, red and green. Red posts signify the start of a stormwater facility maintenance area, and green posts signify the end of the maintenance area. Dimensions are the same as [https://www.oregon.gov/odot/engineering/202207/TM570.pdf ODOT TM570 Type 2 flexible plastic posts], but these omit the 4″ reflective sheeting bands. No other information is added to these posts.
* '''Type S2''' markers are the same size as the Type 2 culvert markers above, and have a similar design. A Type S2's top color band is blue instead of green, and the milepoint is replaced by a 5″ × ¼″ black stripe which can be optionally turned into an arrow to indicate the direction or location of the stormwater facility. Otherwise, both Type 2 and Type S2 display the same information.
* '''Type S3''' markers are essentially DFI numbers stamped onto access covers like manholes and vaults to identify underground stormwater facilities. For durability, ink is not used.

ODOT appears to have used other types of markers to identify and locate culverts and stormwater facilities before; however, their usage appears to be limited, and not much information is known about them:

* Some highways, such as stretches of [[US Route 101|US-101]] and [[Oregon Route 6|OR-6]] near Tillamook, have white paddles with a white button reflector affixed to the top and the milepoint in black Series B towards the bottom. These almost always appear to be found in locations with guardrails and almost always are accompanied by a Type 1 culvert marker on the ground and/or the guardrail. Many of these appear weathered, indicating that they may be years or decades old.
* A section of [[Oregon Route 224|OR-224]] from roughly Carver to Barton has small yellow markers with the milepoint in black FHWA Series C text and a reflective blue circle below. These appear to mark the locations of culverts or other drainage facilities. The milepoints correspond to the mileage along the Clackamas Highway #171.
* A couple highways in the central Willamette Valley (a section of [[Oregon Route 221|OR-221]] south of Dayton, [[Oregon Route 51|OR-51]] in Independence, possibly more) have small, narrow green markers at locations of culverts. A circular ODOT logo is on top with sections below for other information about the culvert, including milepoint, kilometerpoint, diameter in inches, length in feet, type, description, and reference point in feet. An Oregon Utility Notification Center "Stop - Call Before You Dig!" logo is at the bottom. Curiously, many of these markers along [[Oregon Route 221|OR-221]] omit all information except the description (usually "CULVERT"). For comparison, the one along [[Oregon Route 51|OR-51]] in Independence has the information affixed to the post using stickers; the text is white on a green background in FHWA Series B and/or C.

== County Roads ==

Not all counties place inventory markers on their bridges or at their culverts.

[[File:Mp-county-clackamas-culvert-examples.png|108px|thumb]]
=== Clackamas County ===

Clackamas county does not place inventory markers on its bridges, but does utilize two different kinds of culvert markers on its roads:

* White metallic rounded rectangles, marked at culverts in hundredths of a mile
* White delineator wickets embedded in the ground, also marked at culverts in hundredths of a mile

Each of these markers contains the mileage in tenths or hundredths of a mile and a 5-digit county road number. This number can sometimes span two different roads if they comprise a longer route, such as Stafford and Wilsonville Roads.

At jurisdictional boundaries, the white markers can also sometimes be found with "BCM" and "ECM", for "begin county maintenance" and "end county maintenance" respectively, depending on the direction of travel. On the wickets, no other information (such as mileposts or road numbers) are present; the metal rectangle versions of these posts ''can'' contain the road number, but again no mileage is indicated.

Zero mileposts can be found in both types.

[[File:Mp-county-clatsop-bridge-examples.png|182px|thumb]]
=== Clatsop County ===

Clatsop County marks its bridges with a small rectangular inventory marker placed on the bridge itself. These markers display the bridge name, ODOT bridge number, Clatsop County bridge number, and the milepoint in white FHWA Series B text on a green background. They also have a "Clatsop County" stamp on them, similar to [[Mileposts#Clatsop County|mileposts placed on county roads around 2015]].

In addition, Clatsop County places street sign blade-sized signs at the bridge itself, mounted on a taller post presumably for motorist assistance. These signs display the waterway name in large text, with the Clatsop County bridge number and bridge name below it in much smaller lettering. All text on this sign is in FHWA Series B. Like the 2015-era mileposts, these also have "Clatsop County" stamped in them, as well as the date of installation written on them in permanent marker; for example, the sign at Humbug Creek was installed in October 2012.

At culverts, Clatsop County uses green wickets with an orange reflective square and the milepoint below in tenths, hundredths or even ''thousandths'' of a mile, without identifying any sort of road name or number. The typeface used is a thinner stroke version of Helvetica Inserat Roman.

[[File:Mp-county-linn-bridge.png|60px|thumb]]

=== Linn County ===

Linn County places inventory markers on its bridges that displays information like road number, milepoint, bridge number, road name and body of water crossed. These usually appear on both sides of the bridge and use some form of Helvetica for the typeface. Newer versions of these markers use a reflective sheeting, have a border and incorporate rounded corners.

[[File:Mp-county-marion-culvert.png|30px|thumb]]
=== Marion County ===

Marion County rarely places inventory markers on its culverts. As of July 2025, the only known marker is placed along Champoeg Rd. NE westbound as it crosses Ryan Creek near Champoeg State Heritage Area. The retroreflective marker has a white background, with sharp points at the corners except for a rounded lower-left corner. What appears to be the culvert's NBIS number is placed vertically in the center in blue FHWA Series C text. No other road, milepoint or structural information can be gleaned from the marker. According to Google Street View, the marker was placed on a wooden post sometime between September 2012 and May 2019.

It is unknown if other markers, or variations of this one, exist in the county, as well as how long these markers have been in use.

[[File:Mp-county-polk-bridge.png|60px|thumb]]
=== Polk County ===

Polk County places inventory markers on its bridges, usually just a single marker placed behind one of the diagonally striped hazard signs at the corners of the bridge. This MUTCD yellow-colored marker is about 4 inches wide by 8 inches tall and only displays the bridge's NBIS number vertically on the right side in black FHWA Series B text. No other road, milepoint or structural information can be gleaned from the marker, unless there is information on the back where it cannot easily be seen. It is also unknown if other markers, or variations of this one, exist in the county, as well as how long these markers have been in use.

[[File:Mp-county-tillamook-bridge.png|107px|thumb]]
=== Tillamook County ===

Tillamook County places blue inventory markers on bridges it maintains which list the bridge name, the county bridge number (including the county road number in the first segment), the ODOT bridge number, and the body of water being crossed. All text on the markers is in FHWA Series B. While it isn't known at this time when these markers were placed, their reflective background suggests they may have been placed around the same time as the [[Mileposts#Tillamook County|newer reflective mileposts used on county roads]] since around 2015.

[[File:Mp-county-washington-bridge-culvert.png|126px|thumb]]
=== Washington County ===

Washington County marks most of its bridges and culverts with markers similar to [[Mileposts#Washington County|county road identifiers on mileposts]], with the word "ROAD" replaced with "BRIDGE" or "CULVERT" appropriately. The numerals are larger than the road markers, and the legend text appears to be less condensed. Numerals are in Series B, C or D. No other mileage or route identification information can be found on these markers. A newer version of this marker was placed on the Scholls Ferry Road bridge over the Tualatin River when it was replaced in 2008.

== City Roads ==

[[File:Mp-city-beaverton-bridge-culvert-examples.png|258px|thumb]]
=== Beaverton ===

The City of Beaverton has placed at least three different versions of small green markers at its bridges:

* One (possibly older) version has "Beaverton Bridge" in FHWA Series B on top, the City of Beaverton's centennial seal in the middle, and a white box below containing a green "BB-" (presumably for "Beaverton Bridge") and the bridge number in FHWA Series B on the bottom.
* Another (possibly newer) version retains the same "Beaverton Bridge" on top, but with the City of Beaverton's logo in the middle (omitting the "Oregon") and the bridge number in white FHWA Series C lettering on the bottom.
* A third (possibly the newest) version has "BB" (presumably for "Beaverton Bridge") above, the City of Beaverton's logo in the middle (with the "Oregon" this time), and the bridge number below. The "BB" and bridge number are both in white FHWA Series C. The bridge number is also larger than previous versions.

On the first two types of marker, Beaverton appears to use three digits with leading zeroes (e.g. "004") to identify bridges it has built itself; leading zeroes are dropped from the third marker type (e.g. "16"). However, the city may also retain the numbers of bridges it takes over from other jurisdictions. This could be the case with the Johnson Creek Bridge on SW Hart Road, which has the number "19051"; this number more closely resembles those used by Washington County.

In addition to bridges, Beaverton occasionally places similar markers at its culverts. These markers have the design of the "newest" bridge markers, but with "BC" (presumably for "Beaverton Culvert") on top.

[[File:Mp-city-portland-bridge-culvert-examples.png|186px|thumb]]
=== Portland ===

The City of Portland's Bureau of Transportation (PBOT) places inventory markers on many bridges it maintains. These markers feature the logo of either PBOT or its predecessor, the Portland Office of Transportation (PDOT), along with the city's phone number, the road name, the feature it crosses, and a bridge identifier (likely its ODOT number). All text is either FHWA Series B or Series C, aside from the PBOT/PDOT logo which uses condensed versions of both Britannic and Britannic Bold.

In addition, the city's Bureau of Environmental Services (PBES) places markers at culverts. These are white markers with the long edge oriented horizontally. At the top is a blue "City of Portland" in an as-yet unidentified serif font (represented by Goudy Old Style in the example). The PBES logo and city's phone number are on the bottom in the same shade of blue as the "City of Portland" text above. In the middle is presumably the name and some sort of identifier in black Helvetica Bold text.

Bridge and Culvert Inventory Markers

2025-11-18T08:47:05Z

Jonathan: Update Beaverton marker descriptions

'''Bridge and Culvert Inventory Markers''' are signs that identify bridges and culverts for jurisdictional maintenance purposes and occasionally to assist the travelling public. Oregon has placed inventory markers on bridges since around the year 2000, but some counties and cities have used them in decades prior.

== State Highways ==
[[File:Odot-bridge-inventory-marker-examples.png|258px|thumb]]
=== Bridge Inventory Markers ===

By 2001, ODOT started placing standardized inventory markers at some bridges and overpasses. ODOT's logo is at the top, with a phone number underneath it. Information about the bridge — route number, highway number, milepoint, and ODOT bridge number — is placed in the middle, with the name of the feature being crossed below that. Variations do exist, likely as a result of the contractors used on various projects:

* The "ODOT" in the ODOT logo used to be in Helvetica, but has changed typeface in recent years. All other text is in FHWA Series B, though often times it is condensed even more to fit additional information.
* Phone numbers change depending on the location of the marker and are included as a public safety service. Numbers currently documented include:
** 503-378-2299: 24/7 ODOT Dispatch Center
** 503-283-5859: ODOT Region 1 (Portland Metro Area) Dispatch Center
** 503-362-0457: ODOT Region 2 (NW Oregon) Dispatch Center
** 541-296-2215: ODOT Maintenance District 9 (The Dalles)
* Phone numbers sometimes have dashes in between them.
* Some markers display the text "EMERGENCY ONLY" below the phone number in Series D.
* Interstate routes are displayed with an "I-" in front of the number; by comparison, US and state routes are usually not prefixed by "US" or "OR".
* Milepoints are usually to two decimal points, though some markers exist with only a single decimal point.
* All letters on the markers used to be in all caps; however, the intersecting feature text can sometimes be found in mixed case, such as in markers along the [[Oregon Route 18|Newberg-Dundee Bypass]].
* The text in the intersecting feature section is usually centered, but can sometimes also be left-aligned.
* Milepoints can be negative. If this is the case, they will be displayed with a minus sign in front of the milepoint (e.g. MP -0.52). Negative mileage used to be known as "X-mileage", though there are no known inventory markers that use an "X" instead of a "-".

While many of ODOT's inventory markers legibly display correct information, quite a few do not:

* Some markers place the highway number in the "RTE" section and vice versa – for example, the marker at Mills Bridge on [[Oregon Route 6|OR-6]] displays Route 37 and Highway #6
* Some markers display the wrong route number – for example, the marker on [[Oregon Route 202|OR-202]] across Beneke Creek erroneously displays [[Oregon Route 47|OR-47]] in the "RTE" section
* Some markers on unsigned or formerly-unsigned state routes place the route number in the "RTE" section, but place a condensed abbreviation of the highway name in "HWY" – for example, markers on [[Oregon Route 103|OR-103]] display "Fishhawk F" in illegibly-small condensed Type B
* Some markers display a non-existent route – for example, markers on [[Oregon Route 194|OR-194]] erroneously state they are on "US-51"
* Some markers display redundant information – for example, some markers on OR-18 display the highway number and/or milepoint inside the intersecting feature section in addition to their usual spots

=== Culvert and Stormwater Facility Markers ===

Around 2013, ODOT started placing standardized markers at culverts and stormwater facilities. For culverts, two types of markers are defined in [https://www.oregon.gov/odot/engineering/202207/RD398.pdf ODOT Standard Drawing RD398], aptly named Type 1 and Type 2.

* '''Type 1''' markers are 4″ × 6–12″ strips of green thermoplastic tape affixed to the road, with no other information added.
* '''Type 2''' markers are 3½″ × 13¼″ white panels with a green stripe at the top. "ODOT" appears above the stripe. A number appears below the stripe — either the Drainage Facility ID (or "DFI number") if the culvert span is less than 6 feet, or the Bridge Structure ID if the culvert span is between 6 and 20 feet. Below the number is the culvert milepoint. All text on the marker is FHWA Series C, called "Type C font" in the drawing.

Stormwater facilities have three types of markers defined in [https://www.oregon.gov/odot/engineering/202207/RD399.pdf ODOT Standard Drawing RD399], named Type S1, S2 and S3.

* '''Type S1''' markers are flexible plastic posts embedded into the ground in two colors, red and green. Red posts signify the start of a stormwater facility maintenance area, and green posts signify the end of the maintenance area. Dimensions are the same as [https://www.oregon.gov/odot/engineering/202207/TM570.pdf ODOT TM570 Type 2 flexible plastic posts], but these omit the 4″ reflective sheeting bands. No other information is added to these posts.
* '''Type S2''' markers are the same size as the Type 2 culvert markers above, and have a similar design. A Type S2's top color band is blue instead of green, and the milepoint is replaced by a 5″ × ¼″ black stripe which can be optionally turned into an arrow to indicate the direction or location of the stormwater facility. Otherwise, both Type 2 and Type S2 display the same information.
* '''Type S3''' markers are essentially DFI numbers stamped onto access covers like manholes and vaults to identify underground stormwater facilities. For durability, ink is not used.

ODOT appears to have used other types of markers to identify and locate culverts and stormwater facilities before; however, their usage appears to be limited, and not much information is known about them:

* Some highways, such as stretches of [[US Route 101|US-101]] and [[Oregon Route 6|OR-6]] near Tillamook, have white paddles with a white button reflector affixed to the top and the milepoint in black Series B towards the bottom. These almost always appear to be found in locations with guardrails and almost always are accompanied by a Type 1 culvert marker on the ground and/or the guardrail. Many of these appear weathered, indicating that they may be years or decades old.
* A section of [[Oregon Route 224|OR-224]] from roughly Carver to Barton has small yellow markers with the milepoint in black FHWA Series C text and a reflective blue circle below. These appear to mark the locations of culverts or other drainage facilities. The milepoints correspond to the mileage along the Clackamas Highway #171.
* A couple highways in the central Willamette Valley (a section of [[Oregon Route 221|OR-221]] south of Dayton, [[Oregon Route 51|OR-51]] in Independence, possibly more) have small, narrow green markers at locations of culverts. A circular ODOT logo is on top with sections below for other information about the culvert, including milepoint, kilometerpoint, diameter in inches, length in feet, type, description, and reference point in feet. An Oregon Utility Notification Center "Stop - Call Before You Dig!" logo is at the bottom. Curiously, many of these markers along [[Oregon Route 221|OR-221]] omit all information except the description (usually "CULVERT"). For comparison, the one along [[Oregon Route 51|OR-51]] in Independence has the information affixed to the post using stickers; the text is white on a green background in FHWA Series B and/or C.

== County Roads ==

Not all counties place inventory markers on their bridges or at their culverts.

[[File:Mp-county-clackamas-culvert-examples.png|108px|thumb]]
=== Clackamas County ===

Clackamas county does not place inventory markers on its bridges, but does utilize two different kinds of culvert markers on its roads:

* White metallic rounded rectangles, marked at culverts in hundredths of a mile
* White delineator wickets embedded in the ground, also marked at culverts in hundredths of a mile

Each of these markers contains the mileage in tenths or hundredths of a mile and a 5-digit county road number. This number can sometimes span two different roads if they comprise a longer route, such as Stafford and Wilsonville Roads.

At jurisdictional boundaries, the white markers can also sometimes be found with "BCM" and "ECM", for "begin county maintenance" and "end county maintenance" respectively, depending on the direction of travel. On the wickets, no other information (such as mileposts or road numbers) are present; the metal rectangle versions of these posts ''can'' contain the road number, but again no mileage is indicated.

Zero mileposts can be found in both types.

[[File:Mp-county-clatsop-bridge-examples.png|182px|thumb]]
=== Clatsop County ===

Clatsop County marks its bridges with a small rectangular inventory marker placed on the bridge itself. These markers display the bridge name, ODOT bridge number, Clatsop County bridge number, and the milepoint in white FHWA Series B text on a green background. They also have a "Clatsop County" stamp on them, similar to [[Mileposts#Clatsop County|mileposts placed on county roads around 2015]].

In addition, Clatsop County places street sign blade-sized signs at the bridge itself, mounted on a taller post presumably for motorist assistance. These signs display the waterway name in large text, with the Clatsop County bridge number and bridge name below it in much smaller lettering. All text on this sign is in FHWA Series B. Like the 2015-era mileposts, these also have "Clatsop County" stamped in them, as well as the date of installation written on them in permanent marker; for example, the sign at Humbug Creek was installed in October 2012.

At culverts, Clatsop County uses green wickets with an orange reflective square and the milepoint below in tenths, hundredths or even ''thousandths'' of a mile, without identifying any sort of road name or number. The typeface used is a thinner stroke version of Helvetica Inserat Roman.

[[File:Mp-county-linn-bridge.png|60px|thumb]]

=== Linn County ===

Linn County places inventory markers on its bridges that displays information like road number, milepoint, bridge number, road name and body of water crossed. These usually appear on both sides of the bridge and use some form of Helvetica for the typeface. Newer versions of these markers use a reflective sheeting, have a border and incorporate rounded corners.

[[File:Mp-county-marion-culvert.png|30px|thumb]]
=== Marion County ===

Marion County rarely places inventory markers on its culverts. As of July 2025, the only known marker is placed along Champoeg Rd. NE westbound as it crosses Ryan Creek near Champoeg State Heritage Area. The retroreflective marker has a white background, with sharp points at the corners except for a rounded lower-left corner. What appears to be the culvert's NBIS number is placed vertically in the center in blue FHWA Series C text. No other road, milepoint or structural information can be gleaned from the marker. According to Google Street View, the marker was placed on a wooden post sometime between September 2012 and May 2019.

It is unknown if other markers, or variations of this one, exist in the county, as well as how long these markers have been in use.

[[File:Mp-county-polk-bridge.png|60px|thumb]]
=== Polk County ===

Polk County places inventory markers on its bridges, usually just a single marker placed behind one of the diagonally striped hazard signs at the corners of the bridge. This MUTCD yellow-colored marker is about 4 inches wide by 8 inches tall and only displays the bridge's NBIS number vertically on the right side in black FHWA Series B text. No other road, milepoint or structural information can be gleaned from the marker, unless there is information on the back where it cannot easily be seen. It is also unknown if other markers, or variations of this one, exist in the county, as well as how long these markers have been in use.

[[File:Mp-county-tillamook-bridge.png|107px|thumb]]
=== Tillamook County ===

Tillamook County places blue inventory markers on bridges it maintains which list the bridge name, the county bridge number (including the county road number in the first segment), the ODOT bridge number, and the body of water being crossed. All text on the markers is in FHWA Series B. While it isn't known at this time when these markers were placed, their reflective background suggests they may have been placed around the same time as the [[Mileposts#Tillamook County|newer reflective mileposts used on county roads]] since around 2015.

[[File:Mp-county-washington-bridge-culvert.png|126px|thumb]]
=== Washington County ===

Washington County marks most of its bridges and culverts with markers similar to [[Mileposts#Washington County|county road identifiers on mileposts]], with the word "ROAD" replaced with "BRIDGE" or "CULVERT" appropriately. The numerals are larger than the road markers, and the legend text appears to be less condensed. Numerals are in Series B, C or D. No other mileage or route identification information can be found on these markers. A newer version of this marker was placed on the Scholls Ferry Road bridge over the Tualatin River when it was replaced in 2008.

=== Beaverton ===

The City of Beaverton has placed at least three different versions of small green markers at its bridges:

* One (possibly older) version has "Beaverton Bridge" in FHWA Series B on top, the City of Beaverton's centennial seal in the middle, and a white box below containing a green "BB-" (presumably for "Beaverton Bridge") and the bridge number in FHWA Series B on the bottom.
* Another (possibly newer) version retains the same "Beaverton Bridge" on top, but with the City of Beaverton's logo in the middle (omitting the "Oregon") and the bridge number in white FHWA Series C lettering on the bottom.
* A third (possibly the newest) version has "BB" (presumably for "Beaverton Bridge") above, the City of Beaverton's logo in the middle (with the "Oregon" this time), and the bridge number below. The "BB" and bridge number are both in white FHWA Series C. The bridge number is also larger than previous versions.

Beaverton appears to use three digits with leading zeroes (e.g. "004") to identify bridges it has built itself. However, the city may also retain the numbers of bridges it takes over from other jurisdictions. This could be the case with the Johnson Creek Bridge on SW Hart Road, which has the number "19051"; this number more closely resembles those used by Washington County.

In addition to bridges, Beaverton occasionally places similar markers at its culverts. These markers have the design of the "newest" bridge markers, but with "BC" (presumably for "Beaverton Culvert") on top.

=== Portland ===

The City of Portland's Bureau of Transportation (PBOT) places inventory markers on many bridges it maintains. These markers feature the logo of either PBOT or its predecessor, the Portland Office of Transportation (PDOT), along with the city's phone number, the road name, the feature it crosses, and a bridge identifier (likely its ODOT number). All text is either FHWA Series B or Series C, aside from the PBOT/PDOT logo which uses condensed versions of both Britannic and Britannic Bold.

In addition, the city's Bureau of Environmental Services (PBES) places markers at culverts. These are white markers with the long edge oriented horizontally. At the top is a blue "City of Portland" in an as-yet unidentified serif font (represented by Goudy Old Style in the example). The PBES logo and city's phone number are on the bottom in the same shade of blue as the "City of Portland" text above. In the middle is presumably the name and some sort of identifier in black Helvetica Bold text.

Pioneer Highway

2025-08-08T09:20:58Z

Jonathan: Added pre-1927 information regarding Milton A. Miller

{{UnderConstruction}}
The '''Pioneer Highway''' — also known by a couple other names — refers to a plan first proposed in 1927 to route a north-south highway between Portland and Salem via the historic townsite of Champoeg. In the mid-1930s, this plan eventually evolved into an east-west highway between [[US Route 99W|US-99W]] in Newberg and [[US Route 99E|US-99E]] in Aurora via Champoeg, called the '''Champoeg Memorial Highway''' with its own alternative names. While a survey of a 7.13-mile section was completed in February 1936, any plans for a highway through the townsite were ultimately dropped due to issues acquiring right-of-way, burdensome funding regulations, and in-fighting between competing groups that wished to shape the future of what would become the Champoeg State Heritage Area. To this day, there is no state highway that passes by or through Champoeg.

== Routing ==
=== North-South Alignment ===
Very little is known about the exact routing of the north-south highway between Salem and Champoeg, but a couple of different rough routings were proposed north to Portland. When first suggested to the Oregon State Highway Commission in 1927, the highway would have crossed the Willamette River on a bridge at Butteville, a couple miles east of Champoeg, but no defined routing to Portland was mentioned<ref name="oshc_1927-08-30_2208">Oregon State Highway Commission minutes, 30 August 1927, p. 2208</ref>. In 1929, the highway (now referred to as the "Pioneer Highway") was further suggested to the commission that this highway could be routed "via the proposed Tualatin Tunnel" through the West Hills<ref name="oshc_1929-09-26_2569-2570" />; this tunnel was 1¼ miles long and would have connected what is now [[Oregon Route 10|OR-10]] to the Marquam Gulch area near downtown Portland<ref name="oshc_1930-09-09_2794">Oregon State Highway Commission minutes, 9 September 1930, p. 2794</ref>. By 1931, it was suggested that the Pioneer Highway be 100 feet wide and utilize ''two'' arterial highways, one for passenger vehicles and the other for trucks<ref name="oshc_1931-07-30_3033">Oregon State Highway Commission minutes, 30 July 1931, p. 3033</ref>.

In 1932, the commission received a petition that defined the routing as "Salem to Champoeg, thence to Butteville, thence crossing the Willamette River to Clackamas County Market Road No. 6 [modern-day Wilsonville Road], thence to Grahams Ferry Road, thence to Tualatin, thence to Portland via Boones Ferry Road"<ref name="oshc_1932-02-05_3225">Oregon State Highway Commission minutes, 5 February 1932, p. 3225</ref>. It is not known whether this alignment ends at Terwilliger Blvd. or at [[US Route 99E|Macadam Ave.]] by way of Taylors Ferry Road.

=== East-West Alignment ===

According to an OSHD Right of Way Map from February 1936<ref name="oshd_row_5B-2-14">Oregon State Highway Department. "Drawing No. 5B-2-14: Champoeg Memorial Highway, Located Line, Champoeg-Wilsonville Section", February 1936</ref>, the western terminus of the Champoeg Memorial Highway would have been slightly to the south of the Pioneer Memorial Building in the Champoeg State Heritage Area. From there, it would have roughly paralleled the Willamette River easterly along its southern bank, cutting through the original platted streets of Champoeg in the process. At the historic town of Butteville, about 3 miles from the western terminus, the highway would have stopped following the river and curved to meet present-day Arndt Road east of town. From there, it would run due east along Arndt Road, crossing the Oregon Electric Railroad tracks at Butteville Station and eventually straddling the Marion-Clackamas County line. Finally, after a 6.89-mile journey, the Champoeg Memorial Highway would have split into a pair of 0.24-mile wyes to connect to both directions of a slightly-reconstructed Beaverton-Aurora Highway (marked "Tigard-Aurora Highway" on the ROW map) at its eastern terminus. Today, this location is about 2 miles north of Aurora at the corner of Arndt Road and Airport Road, at the northeast corner of the Aurora State Airport.

In addition to Arndt Road, this highway would have run over portions of present-day Schuler Road near Butteville, as well as parts of the Townsite Trail and Champoeg-Butteville Bike Path in and around Champoeg State Heritage Site.

== History ==
=== Champoeg Townsite ===
Situated on the southern bank of the Willamette River, the former townsite of Champoeg was best known for the Champoeg Meetings between European-American and French-Canadian settlers from 1841 to 1843. After the United States Congress failed to establish a government, these meetings led to a series of votes on May 2, 1843 on whether to form their own provisional government. At the time, control of the territory was disputed between the United States and the United Kingdom, and the British Hudson's Bay Company (HBC) had a sizeable influence in the region. The HBC initially convinced all the French-Canadians to vote against the provisional government twice. During the third vote, two French-Canadians switched their votes to side with the European-Americans, thus establishing a provisional government, 52 to 50. While it was originally hoped that Champoeg would become the capital of this new government, Oregon City ended up being selected instead when the Oregon Territory was formed in 1848.

While the town continued to exist and grow after its failed bid to become the capital, disaster would soon strike. Due to exceedingly heavy rains in November 1861, the town was flooded and mostly washed away on December 2. It was never rebuilt.

=== Champoeg Park ===
On June 15, 1901, the Oregon Secretary of State was deeded 1 square rod (or 30¼ square yards) of land at the Champoeg townsite<ref name="or_parks_history_108">Oregon State Parks Department. ''History of the Oregon State Parks'', 1 July 1965, p. 108</ref>. A monument, dedicated to the 52 settlers who voted to create the provisional government in 1843, was placed upon the land, which became known as ''Provisional Government Park'' by 1906<ref name="or_parks_history_108" /><ref name="oreg_1906-05-02_10">''The Morning Oregonian''. "Celebrates at Champoeg," 2 May 1906, p. 10</ref>. In 1913<ref name="or_parks_100-years_10">Aurand, Marin and Marc Carpenter. ''"So the Future Will Have a Place": The First Century of Oregon State Parks,'' Oregon Parks and Recreation Department, 2022, p. 10</ref> (some sources say 1912<ref name="or_parks_history_109">''History of the Oregon State Parks'', p. 109</ref>), jurisdiction of the park was turned over to the newly-created Board of Control, whose purpose was to "coordinate the management of state institutions, construction of state buildings, and other duties assigned by the legislature"<ref name="orstarch_2003_board-of-control-history">Halvorson, Gary D. [https://records.sos.state.or.us/ORSOSWebDrawer/Record/7284505/File/document "Oregon State Board of Control Agency History,"] Oregon State Archives, 2003, last accessed 7 August 2025</ref>. This was likely done because Oregon did not have a government body dedicated to administering state-owned park lands at the time.

This was rectified on February 28, 1921, when the state legislature allowed the Oregon State Highway Commission to purchase land along state highways for beautification and scenic preservation purposes<ref name="or_parks_100-years_15">Aurand, p. 15</ref>. This authority was bolstered in 1925, when the commission was specifically allowed to purchase and maintain "parks, parking places, camp sites, public squares and recreation grounds," whether along a highway or not<ref name="or_parks_100-years_16">Aurand, p. 16</ref>. Despite the commission's new department dedicated to park lands, Provisional Government Park was still administered by the Board of Control at the time, and would be for the foreseeable future.

=== Pioneer Highway ===
[[File:Ohs_milton-miller.jpg|150px|thumb|right|Milton A. Miller]]
When Provisional Government Park first opened, it was designed to accommodate steamships instead of the nascent automobile; this attitude changed in the 1910s and 1920s, as supporters and supervisors desired highways by which new visitors could arrive<ref name="or_parks_100-years_18">Aurand, p. 18</ref>. Throughout the 1920s and 1930s, perhaps no one supporter would push for a new highway between Portland and Salem via Champoeg more than Milton A. Miller. A 14-year state legislator and Collector of Internal Revenue in Portland from 1913 to 1921, Miller began associating himself with Provisional Government Park in 1918 when he spoke at the dedication of the Pioneer Memorial Building at Champoeg on May 2<ref name="1967_champoeg-book_282-284">Hussey, pp. 282-284</ref>.

With the passage of the Market Road Tax Bill on June 3, 1919, the state was able to help fund county market roads to assist with maintenance costs<ref name="orblue_2015_292">Brown, Kate (comp.). ''2015-2016 Oregon Blue Book Almanac & Fact Book,'' Oregon Secretary of State, Archives Division, 2015, p. 292</ref>. Marion County benefitted greatly from the new market road system — by 1929, it would have 94 defined market roads within its borders, the most of any county<ref name="oshc_1929-09-26_2569-2570">Oregon State Highway Commission minutes, 26 September 1929, pp. 2569-70</ref>. Provincial Government Park was well-served under this system, with Market Road No. 12 (Yergen Corner-Newberg Road) passing by Champoeg and Market Road No. 62 (Champoeg-Monument Park Road) leading to Provincial Government Park itself<ref name="oshd_c1929_marion-co-market-roads">Oregon State Highway Department. [https://www.oregon.gov/ODOT/ETA/Publications/Market-Roads.pdf "Marion County Market Roads,"] c. 1929, last accessed 7 August 2025</ref>.

While it is thought that Miller first advocated for a Portland-Champoeg-Salem highway as early as 1924<ref name="1967_champoeg-book_284">Hussey, p. 284</ref>, he started by imploring the OSHC to improve Marion County Market Road No. 62 at their meeting on July 29, 1926, advocating on behalf of the Sons and Daughters of Oregon Pioneers<ref name="oshc_1926-07-29_2026">Oregon State Highway Commission minutes, 29 July 1926, p. 2026</ref>. Roy A. Klein, State Highway Engineer at the time, investigated the matter, concluding at the following meeting on August 26 that $6,580 was set aside in the 1926 market road program for "the grading, gravel surfacing and bridging" of this road<ref name="oshc_1926-08-26_2040">Oregon State Highway Commission minutes, 26 August 1926, p. 2040</ref>. This improvement did not appear to satisfy Miller, who, again representing the Sons and Daughters of Oregon Pioneers, returned to the commission on June 23, 1937 to request that Market Road No. 62 now be paved<ref name="oshc_1927-06-23_2175">Oregon State Highway Commission minutes, 23 June 1927, p. 2175</ref>. The commission declined his request, stating:

{{OSHCMinutes|quote=this road could not be improved without putting it on the state highway system and since it was not connected with any state highway, this could not be considered. Commissioner Smith of Marion County, who was present, stated that the Champoeg road was a part of the Marion County market road system and had recently been improved by widening the grade, building new bridges and resurfacing.
