The U.S. Bicycle Route System (USBRS) is a developing network of officially numbered interstate bicycle routes that connect America’s cities, suburbs, and rural areas.
The National Corridor Plan is a corridor-level plan for the development of future U.S. Bicycle Routes.
Corridors are not routes, but 50-mile wide areas where routes may be developed, linking key destinations, urban centers, that take into account the natural landscape.
Corridors can be added, removed, or shifted by states as opportunities and interest develops.
U.S. Bicycle Routes are defined as routes that connect two or more states, a state and an international border, or other U.S. Bicycle Routes.
U.S. Bicycle Routes may be on roads or trails suitable for bicycle travel.
State departments of transportation (DOTs) apply for U.S. Bicycle Route numbered designation, and work in coordination with local agencies, organizations, and volunteers in planning and choosing routes.
U.S. Bicycle Routes are catalogued and designated by the American Association of State Highway Transportation Officials (AASHTO), the lead non-profit organization supporting state DOTs.
U.S. Bicycle Routes will be designated with numbers and may be mapped and signed.
Projects to help create U.S. Bicycle Routes can be supported through federal, state, and private funds.
On September 24, 2015, Arizona became part of the United States Cycling Route System, an interstate network of designated cycling routes spanning 11,424 miles of roadway in 23 states and the District of Columbia.
