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

Bridge Inventory Markers

Culvert Markers

County Roads

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

Mp-county-clatsop-bridge-examples.png

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 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 hundredths of a mile, without identifying any sort of road name or number. The typeface used is a thinner stroke version of Helvetica Inserat Roman.

  • A bridge inventory marker for the Humbug Bridge over Humbug Creek on Lower Nehalem Road, 2021

  • A bridge sign for the Humbug Bridge over Humbug Creek on Lower Nehalem Road, 2021

  • A green wicket culvert marker at MP 9.02 on Lower Nehalem Rd., 2014


Mp-county-linn-bridge.png

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.

  • A bridge inventory marker at MP 1.16 on Hofer Road, 2016

  • A bridge inventory marker at MP 0.15 on Higbee Road, 2016


Mp-county-tillamook-bridge.png

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 newer reflective mileposts used on county roads since around 2015.

  • A bridge inventory marker for the Cronin Creek Bridge on Foss Road, 2021

  • A bridge inventory marker for the Salmonberry Bridge over the Salmonberry River on Foss Road, 2021

  • A bridge inventory marker for the CCC Bridge over the Nehalem River on Foss Road, 2021


Mp-county-washington-bridge-culvert.png

Washington County

Washington County marks most of its bridges and culverts with markers similar to 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.

  • A Washington County bridge marker on Cochran Road near Reehers Camp, 2019


City Roads

Mp-city-beaverton-bridge-culvert-examples.png

Beaverton

The City of Beaverton has placed at least two different versions of small green markers at its bridges. The legend at the top of both versions says "Beaverton Bridge" in FHWA Series B. Below there:

  • One (possibly older) version has the City of Beaverton's centennial seal in the middle, with a white box below containing a green "BB-" (presumably for "Beaverton Bridge") and the bridge number in FHWA Series B.
  • Another (possibly newer) version has the City of Beaverton's logo in the middle (omitting the "Oregon") with the bridge number in white FHWA Series C lettering below.

In addition, Beaverton places similar markers at its culverts. These markers have the design of the "newer" bridge markers, with "BC" (presumably for "Beaverton Culvert") on top and the city logo in the middle. Unlike the bridge markers, these ones keep the word "Oregon" in the logo. The culvert number is also larger on these markers than the bridge markers, and is in FHWA Series D.

  • A Beaverton bridge inventory marker with city logo on Hall Blvd., 2021

  • A Beaverton bridge inventory marker with city seal on Broadway, 2021

  • A Beaverton culvert inventory marker with city logo on SW Griffith Dr., 2021


Mp-city-portland-bridge-culvert-examples.png

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.

  • A PDOT bridge inventory marker on N Portland Road near St. Johns, 2015

  • A PBES culvert inventory marker near Kelley Point, 2014
