NY 78A
NY 78A was an alternate route of NY 78 in Erie County between NY 78 in East Aurora and NY 35 (now US 20) in Lancaster. The route began at the modern intersection of Main (then-US 20) and Maple streets in East Aurora and followed Maple Street, Jamison and Bowen roads, and Clinton (NY 354) and Aurora streets to a terminus at Broadway (NY 35) in Lancaster. It was assigned c. 1932 after NY 78 was rerouted to follow US 20 and Transit Road instead between East Aurora and Depew. The NY 78A designation was short-lived as it was removed c. 1938. Its routing is now part of several county routes as well as NY 354.
