The route runs concurrently with both of the other two routes into Wapakoneta, and with State Route 198 only north of the village.

Route description

State Route 501 runs through portions of Auglaize and Allen Counties. The highway is not incorporated within the National Highway System, a system of highways established to be the most important for the nation's economy, mobility and defense.^[2]

History

When first established in 1937, State Route 501 ran from downtown Wapakoneta to its current northern terminus at State Route 117.^[3][4] When a new southern bypass of Wapakoneta was completed in 1961 and U.S. Route 33 was re-routed along it, State Route 501, along with State Route 67 and State Route 198, were extended south from downtown along Willipie Street to a new common terminus at the re-routed U.S. Route 33.^[5][6]
