Interstate 878 - Nassau Expwy / Route 878 - Rockaway Blvd

Interstate 878New York Route 878

New York Route 878 follows the Nassau Expressway between Howard Beach and John F. Kennedy International Airport in south Queens. NY 878 constitutes a freeway from Cross Bay and Conduit Boulevards eastward to Hangar Boulevard near Rockaway Boulevard. Rockaway Boulevard continues the state route southeast as a six-lane surface arterial along the airport boundary to Cedarhurst and Nassau County. Interstate 878 overlays Nassau Expressway for 0.70 miles between the interchange with I-678 (Van Wyck Expressway) and the freeway end at Hanger Boulevard. The designation is unsigned, although New York State Reference Markers identify the stretch as "878I", indicating its status as an Interstate highway.1

Constructed in the mid and late 1960s, the first segment of the Nassau Expressway opened to traffic in 1971. Built were the eastbound lanes between Cross Bay Boulevard and Interstate 678 (Van Wyck Expressway). Signs initially referenced the road as part of Interstate 78.1

As originally envisioned, the Nassau Expressway was part of the overall alignment proposed for Interstate 78 through Brooklyn and Queens, New York. Planning began in 1947 and by 1955, the route of the Nassau Expressway took I-78 east from the proposed Bushwick Expressway, at the interchange with Cross Bay Boulevard, to the planned south end of the Clearview Expressway. The Nassau Expressway eastward exter to Atlantic, Long and Lido Beaches was included as an unnumbered route.1

Cancellation of the Nassau Expressway commenced in 1967, as community opposition resulted in the removal of the Long Beach extension. The Bushwick Expressway was similarly dropped in 1967, leaving the Nassau Expressway disconnected from Interstate 78. During that time, I-878 arose as a potential number for the Nassau Expressway. Construction continued on the roadway through 1981, but as an at-grade boulevard instead of a full freeway east of JFK Expressway. The remaining segments of the planned Nassau Expressway, from Rockaway Boulevard east to the Nassau County line, were never built due to high costs of grading within the Jamaica Bay watershed. The designations switched in 1989 to I-878 for the Nassau Expressway segment in Queens and NY 878 for the portion in Nassau County.1
