The U.S. Bicycle Route System is a developing national network of bicycle routes, which will link urban, suburban, and rural areas using a variety of appropriate cycling facilities.
To date, 5,847 miles of U.S. Bike Routes have been established in 12 states: Alaska, Kentucky, Illinois, Maine, Maryland, Michigan, Minnesota, Missouri, New Hampshire, North Carolina, Tennessee, and Virginia. Presently, more than 40 states are working to create U.S. Bicycle Routes.
State departments of transportation (DOTs) nominate U.S. Bike Routes for numbered designation through the the American Association of State Highway and Transportation Officials' (AASHTO) Special Committee on U.S. Route Numbering, which is the same committee that assigns numbers to U.S. highways and interstates.
For a route to receive official designation as a U.S. Bicycle Route, it must connect two or more states, a state and an international border, or other U.S. Bicycle Routes.
The National Corridor Plan shows officially designated U.S. Bike Routes as dark, solid lines. The lighter lines indicate corridors where routes may be developed. Corridors can be added or changed based on opportunities or local support.
The USBRS project is a collaborative effort, spearheaded by a task force under the auspices of AASHTO. Members of the task force include officials and staff from state DOTs, the Federal Highway Administration, and nonprofits, including Adventure Cycling Association, the East Coast Greenway Alliance, and Mississippi River Trail, Inc.
