State Route 621 (SR 621, OH 621) is a north–south state highway in the central part of the U.S. state of Ohio. The southern terminus of State Route 621 is at U.S. Route 36 approximately 2.50 miles (4.02 km) northeast of Coshocton, and its northern terminus is adjacent to the North Appalachian Experimental Watershed Station, just north of its intersection with White Eyes Township Road 188, about 5 miles (8.0 km) northwest of the hamlet of Fresno. Continuing north after State Route 621 ends is Coshocton County Road 190.

Established in the early 1940s, State Route 621 is a two-lane spur route whose primary purpose is to provide access to the North Appalachian Experimental Watershed Station from the state highway network. The entirety of the route exists within Coshocton County.

History

1941 marked the year in which State Route 621 made its debut. Its routing originally consisted of the present segment of U.S. Route 36 between its northern junction with State Route 83 north of Coshocton and the current southern terminus of State Route 621, and then the entire current length of State Route 621 up to the location of the North Appalachian Experimental Watershed Station .^[1][2] In 1962, U.S. Route 36 was re-routed out of Coshocton and onto its current alignment that bypasses the city to the north, following the north side of the Tuscarawas River. Part of this re-routing resulted in the southern terminus of State Route 621 being moved to its present location at U.S. Route 36 northeast of Coshocton.^[5][6]

Major intersections

The entire route is in Coshocton County.
