Created in the middle of the 1920s, SR 215 is a two-lane rural highway that primarily serves as a connector between the Noble County villages of Belle Valley and Sarahsville.

The highway runs northeasterly through rural terrain that starts out as open field but quickly transitions into forest.

SR 215 climbs up and down hilly terrain that is generally open field in the foreground, with trees forming a very scenic background.

A few homes now appear alongside the highway as it bends to the southeast, and curves back to the northeast just prior to arriving at its endpoint at a T-intersection with SR 285 just west of Sarahsville.

[6][7] SR 215 would stay this way until 1965, when the highway was extended on the east end, routed along a previously un-numbered roadway heading east from Belle Valley to its current eastern terminus at SR 285 just outside Sarahsville.
