USBR 21 begins at a junction with USBR 30 at Edgewater Park in Cleveland. From Cleveland to Cincinnati, it runs along the Ohio to Erie Trail, concurrent with State Bicycle Route 1, which mostly consists of off-road multi-purpose trails such as the Ohio and Erie Canal Towpath Trail and Little Miami Scenic Trail. There are additional overlaps with USBR 44 Massillon to near Wooster and with USBR 50 from Columbus to Xenia. Past Cincinnati, the route resumes along the Ohio River Trail, concurrent with USBR 25, to the Kentucky state line at Aberdeen.^[6][7]

History

The American Association of State Highway and Transportation Officials (AASHTO) approved the southern segment of USBR 21 in Georgia in 2015^[5] as the first U.S. Bicycle Route in the state. In May 2019, AASHTO approved the northern segment through Kentucky,^[9] which was extended in May 2021 through Ohio to its northern terminus in Cleveland.^[10] In 2022, the route was extended through Tennessee, connecting the two segments.^[2]
