The Robert Moses Causeway begins at the Southern Parkway as a short parkway with four lanes. It runs to the south past Sunrise Highway (NY 27) and Montauk Highway (NY 27A) and then goes over a long bridge over Great South Bay to Captree Island. It then goes over a short drawbridge. On the other side, there is an exit for the Ocean Parkway and Captree State Park. After this exit, the road narrows down to two lanes. It goes over a final bridge to Robert Moses State Park on Fire Island, where it ends.
The first section of the Robert Moses Causeway, between the Southern State Parkway and EXIT RM2 (NY 27A / Montauk Highway) in West Islip, was completed in 1953. The first causeway bridge, which had one northbound and one southbound lane, was opened to traffic in April 1954. The final link of the Robert Moses Causeway opened in 1964.
