This page lists the routes in the Oregon State Highway System.
Summary
Currently, Oregon implements two systems for numbering highways. The first system used was the Oregon State Highway System, in which the Oregon Highway Division (now ODOT) gave a name and number to each individual highway. These were the primary identification for Oregon's state routes. With the implementation of the U.S. Route systems in 1926, Oregon had to devise a new numbering system as to prevent confusion between Oregon highways and U.S. routes. In 1932, the Oregon Route System was created for this purpose, however, the original highway names and numbers were kept by the Oregon Highway Division for internal uses.
The Oregon Route System is what's seen by the public, published on maps, used for general navigation across the state, etc., and includes Interstates and U.S. Highways. These numbers were originally assigned in a pattern, with odd-numbered primary state routes running north-south, the lowest numbered route starting from the eastern part of the state and increasing heading west. Even numbered primary state routes ran east-west, with the lowest numbered route in the northwest corner of the state and increasing to the easternmost part of Oregon. Secondary state routes are 200-series routes. They were assigned with the lowest odd number in the east and increasing to the west; the lowest even number started in the north part of the state and increased heading south.
Oregon Highway numbers and Oregon Route numbers usually do not coincide, so for a given stretch of road, you will have a Highway name and number PLUS an associated route. For example, Pacific Highway #1 (the Highway name/number) is mostly associated with Interstate 5 (the Route number). Highway names/numbers may have many routes associated with it, and Route numbers may have many different segments of Highway associated with it. Some of the Highways do not have an associated Route number. For the sake of simplicity, the following list only contains the Oregon Route System route numbers.
