U.S. Bike Route 66

In 2008 the American Association of State Highway and Transportation Officials (AASHTO) approved a National Corridor Plan for Bicycling Routes that was developed by the Task Force on US Bicycle Routes. Route 66 from Illinois to California is one of the nationally significant corridors in the plan. 

In July 2022, Oklahoma was approved for the U.S. 66 Bike Route designation. 

There is no cost to apply for a road to be designated as a U.S. Bike Route. Signage may be constructed and added as desired by the adjacent communities and jurisdictions along the route.

The process to apply requires the communities and jurisdictions along the route to approve this designation, and then the department of transportation sends the completed application to AASHTO, the organization responsible for numbering highways.
