U.S. Bicycle Route System (USBRS)


The United States Bicycle Route System (USBRS) was established in 1978 by the American Association of State Highway and Transportation Officials (AASHTO) for the purpose of "facilitating travel between the states over routes which have been identified as being more suitable than others for cycling." The National Corridor Plan for the (USBRS) was established by AASHTO in 2008. The Adventure Cycling Association (ACA) manages the USBRS route-designation process nationally for AASHTO. To date, nearly 12,000 miles of the USBRS have been established in 25 states.

As the AASHTO-designated lead for the state of California, Caltrans leadership and involvement is necessary for official USBRS route-designation in California. In response to growing interest statewide in USBRS route-designation, Caltrans has developed a State framework and uniform approach regarding USBRS route-designation.
