Its southern terminus is at a ranger station in Shawnee State Park, and its northern terminus is at SR 73 approximately six miles (9.7 km) southeast of Otway.

Created in the mid-1930s, this two-lane spur highway, whose entire length is just 0.40 miles (0.64 km), provides access to Shawnee State Park from SR 73.

[2] Starting from a ranger station at the entrance to Shawnee State Park, SR 371 starts out heading northerly, then bending to the northeast, bounded by woods on the west side and fields on the east side, with a couple of residences and one church lining the route.

[3] This short spur route was first designated in 1934 along its current path, and has not undergone any major changes since its inception.

[4][5] The entire route is in Union Township, Scioto County.
