State Highways In Oregon

The state highway system of the U.S. state of Oregon is a network of highways that are owned and maintained by the Highway Division of the Oregon Department of Transportation (ODOT). Compared to other states, Oregon's system of numbering is slightly unusual in that there are two numbering systems used. The highway numbers, which correspond to the set of roads maintained by ODOT, are an internal system used in ODOT projects and accounting, and are typically not exposed to the public. The route numbers (Interstate, U.S., and Oregon) appear on maps and roadsigns, and are used to guide the motoring public. The two systems, while largely overlapping, are not congruent; many routes are marked over streets maintained by counties and cities (and thus are not part of the state highway system), and some sections of state highway do not have route numbers. In addition, the highway and route numbers do not agree (except in two situations - a portion of U.S. (route) 26 east of Portland is also Oregon Highway 26 (the Mount Hood Highway, which continues north on Oregon Route 35 while U.S. Route 26 becomes the Warm Springs Highway), and a portion of Oregon Route 47 between Manning and Banks which is co-signed as U.S. 26 is also Oregon Highway 47 (the Sunset Highway).
