Central Park Avenue is a service road of the southernmost section of the New York Thruway (I-87) in Yonkers. Jerome Avenue changes names to become Central Park Avenue at the Bronx-Westchester county line, where I-87 also changes names from the Major Deegan Expressway to the New York Thruway. It runs north as the Thruway's service road until just north of the Cross County Parkway, where it splits off from the Thruway and becomes NY 100.
Prior to the construction of the Thruway, the current CR 47 was part of NY 100, which continued south through the Bronx and into Manhattan.
