NY 13A is a 2.08-mile (3.35 km) north–south spur that bypasses downtown Ithaca by way of the town of Ithaca to the southwest. The route begins at NY 13, NY 34 and NY 96 south of the city and follows the west bank of Cayuga Inlet and the Ithaca Flood Control Channel north into the city, where it ends at NY 79 in Ithaca's West End, an area once dominated by squatters' villages. The highway is named Floral Avenue within the city and Five Mile Drive in the town of Ithaca, so named because it is five miles (8 km) from Cayuga Lake. NY 13A was assigned c. 1938.
