The Nassau Expressway was proposed alongside the never-built Long Beach Expressway. The Long Beach Expressway would have extended east past the Atlantic Beach Bridge along the South Shore to Long Beach and Lido Beach, ending at a junction with the Loop Parkway leading to Jones Beach and the Meadowbrook State Parkway. The Long Beach Expressway would have been a six-lane expressway, running along Reynolds Channel on the north shore of the Long Beach Barrier Island to New York Avenue, then along Park Avenue, which was the primary commercial thoroughfare of Long Beach.
