 === 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".)

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.

 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:

 === 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).

 ==== 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]], and may appear on other primary routes in the forest.

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 type of milepost 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 (Milwaukie-Ripplebrook)|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.

 === 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. They 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)]."

-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 may indicate that concrete mileposts may have been replaced by wooden mileposts due to highway realignment, theft or destruction.
+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.
