 NY 78 was realigned c . 1932 to follow US 20 ( now US 20A ) west from East Aurora to Transit Road , where it turned north onto Transit Road and followed it to Depew . The former routing of NY 78 between East Aurora and Lancaster was redesignated as NY 78A . NY 78 was rerouted one last time c . 1939 to overlap with NY 16 northwest from East Aurora to its junction with Transit Road in West Seneca . The realignment bypassed the southernmost portion of Transit Road , which became NY 187 in the early 1940s .
