The Nassau Expressway was originally planned by Robert Moses to be designated I-878. It would have begun at the Belt Parkway and connected to the Cross Brooklyn Expressway (I-78), which was never built. From there it would have run parallel to the Belt Parkway for a short distance before curving toward the south, crossing the Queens-Nassau border, and running to the south through the Five Towns. From there, it would have crossed the Atlantic Beach Bridge, curved to the east, and ran through Atlantic Beach, Long Beach, and Lido Beach to Point Lookout and the Loop Parkway, where it would have ended. Most of these plans where not ever carried out. A short section of expressway was constructed from the Belt Parkway to Rockaway Boulevard in the vicinity of John F. Kennedy International Airport. A second section, which is a divided boulevard, was constructed from Rockaway Turnpike (CR 257) through the Five Towns to the Atlantic Beach Bridge. It ends on the other side of the bridge at Beech Street (CR 22) and Atlantic Boulevard. The section near the airport is an east/west route, while the section in the Five Towns is a north/south route. The section in the Five Towns does not connect to any other state route.
