Historic Highways
Many of Oregon's highways were first planned and routed in 1917.  By 1933 a slew of secondary highways were criss-crossing the state.  One of the most famous highways is Route 99 which spanned from Canada to Mexico.  First established in the 19-teens, it has continued to improve ever since.  All of these files trace the original route of the state highway.  In some cases files are a grouping of routes or highways.

These files are believed to be as accurate as possible though errors may exist.  Many routes have been field verified.  These are for information only.  I assume no responsibility for use otherwise.  If using these for exploration, please proceed with caution and at your own risk.  Some sections may now be in private ownership, others may be in disrepair.  Backwoods bridges may have washed out resulting in your car ending up in a stream.  Obey all traffic laws.
