The U.S. Bicycle Route System (USBRS) is a network of regionally and nationally significant bicycling routes spanning multiple states. The purpose of the USBRS is to facilitate travel between states on routes identified for long-distance cycling. Michigan is home to three designated U.S. bicycle routes: U.S. Bicycle Route 10, U.S. Bicycle Route 20 and U.S. Bicycle Route 35.
