History
The SR 721 designation was assigned in 1937. Throughout its history, the route has maintained the same alignment in the general vicinity of the boundary between the counties of Darke and Miami. Originally, SR 721 was an unpaved roadway from its southern terminus at SR 49 to its junction with US 36. The portion from that point through Bradford to its northern terminus at SR 185.[1][2] One year after its assignment, SR 721 was paved between SR 49 and Laura.[5] By 1940, the remaining gravel portion of the highway between Laura and US 36 was paved.[6][7]
