Oregon Roads

Oregon


As Mike Wiley explains, there is a difference between State Highways and State Routes. The numbered routes you can follow on a map and that are signed with shields are the State Routes. The named highways can't really be followed without some research, but Oregon mileposts its roads by highway instead of route. Andrew Tompkins notes that US 26 "goes through something like 5 or 6 sets of milepostings starting at 0s for each one (which can be rather aggravating if you don't know the system)." West of Portland, US 30's mileposts increase toward Astoria because that's how the highway is designated. Andrew noted the exception of I-84, "which has one set of milepostings over its entire length in Oregon even though it resides on 2 named highways (#2, the Columbia River Highway from Portland to US-730; and #6, the Old Oregon Trail Highway from US-730 to the ID state line)." Thanks to both Mike and Andrew!

The West Linn or Oregon City Arch Bridge, connecting those two places. Oregon City was important once, but Portland has long since usurped the throne.
