Experience East Tennessee on Two Wheels
Ride U.S. Bicycle Route 21 (USBR 21) from Kentucky to Georgia through Tennessee
The Tennessee route runs north-south beginning at the Cumberland Gap outside Middlesboro, KY, on the TN-KY border and runs south through Knoxville, Athens, Calhoun, and Cleveland before linking up with existing USBR 21 in Georgia via Chattanooga. Originally designated in 2015, USBR 21 connects metro Atlanta to the Tennessee border at Chattanooga and was established in Kentucky in 2018 to connect the Ohio River in Mason County, Kentucky, through the heart of the Bluegrass Region, to the edge of the Cumberland Gap in Tennessee.
The U.S. Bicycle Route System is a project to create publicly-accessible bicycle travel routes across the country. All routes are designated through a state- and federal-level process, with the goal of building broad support for bicycling and bicycle travel in communities across the country.
