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, 5,973 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.
