The U.S. Bicycle Route System (USBRS) is a developing national network of bicycle routes connecting urban and rural communities via signed roads and trails. Created with public input, U.S. Bicycle Routes direct bicyclists to a preferred route through a city, county, or state. As of 2020, over 14,000 miles are currently established in 29 states and Washington DC – and many routes are signed.
The 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. The system is developing through partnerships between transportation agencies, bicycle and trail organizations, and volunteers. Routes are nominated for official designation by state departments of transportation and approved by the American Association of State Highway and Transportation Officials (AASHTO). Designation of a U.S. Bicycle Route means that the state department of transportation and all jurisdictions along the route have given their support.
In California, routes are designed through the following process:

The majority of USBRs have been designated since 2011, and the focus in the
last five years has been on designating routes rather than promoting them.
As expected, there are more plans and intentions to sign, map, and promote
the USBRS than are examples where it has already been done. The National
Corridor Plan may be found here; the image shows the plan for California:

The National Corridor Plan is the blueprint for U.S. Bicycle Route development, and shows what the 50,000-mile network will look like when
complete. Corridors that have been developed into routes and officially
designated as U.S. Bicycle Routes are shown with dark solid lines.
Undeveloped corridors are shown with light dotted lines, and are generally
only concepts until a route is researched and designated. Corridors can be
added or changed depending on the opportunities and interests of a given
state. To date, 14,598 miles of U.S. Bicycle Routes have been established
in 29 states: Alaska, Arizona, California, Connecticut, Florida, Georgia,
Kentucky, Idaho, Illinois, Indiana, Kansas, Maine, Maryland,
Massachusetts, Michigan, Minnesota, Missouri, Nevada, New Hampshire, North
Carolina, Ohio, Pennsylvania, Tennessee, Utah, Vermont, Virginia,
Washington, West Virginia, Wisconsin, and the District of Columbia. The
Adventure Cycling page on the NCP provides a downloadable map.
