By 1956, the highway had been renamed the Long Island Expressway (LIE) and extended east to Queens Boulevard. Although NY 24 intersected the highway twice—where it left the LIE at the BQE and at Queens Boulevard—NY 24 still followed the BQE and Queens Boulevard. The portion of the LIE from Queens Boulevard to the Northern State Parkway (now exit 38) was completed in the late 1950s, at which time NY 24 was rerouted to follow the LIE between Manhattan and East Hills. The original routing of NY 24 from the BQE to Farmingdale was then redesignated as NY 24A. However, unlike NY 24 before it, NY 24A left NY 25 at the junction of Queens Boulevard and Hillside Avenue and followed Queens Boulevard and Jamaica Avenue through Queens. The portion of NY 24 from Manhattan to the Clearview Expressway was co-signed as I-495 by 1960.
