The Southern State Parkway (also known as the Southern State or Southern Parkway) is a 25.53-mile (41.09 km) limited-access highway on Long Island, New York, in the United States. The parkway begins at an interchange with the Belt and Cross Island parkways in Elmont, in Nassau County, and travels east to an interchange with the Sagtikos State Parkway in West Islip, Suffolk County, where it becomes the Heckscher State Parkway. The Southern State Parkway comprises the western portion of unsigned New York State Route 908M (NY 908M), with the Heckscher Parkway occupying the eastern section.
Construction of the highway, designed by Robert Moses, began in 1925. The first section of the parkway opened in 1927. It reached its original eastern terminus (Bay Shore Road) in 1949, and was extended to its current eastern terminus in 1962.
The Southern State Parkway begins at an interchange (exit 25A) with the Belt Parkway and the Cross Island Parkway on the Queens and Nassau County border in Elmont and North Valley Stream. After the interchange, the Southern State proceeds east as a six-lane divided parkway through North Valley Stream, passing north of St. Johns Cemetery before entering exit 13S and exit 13N, which serves Central Avenue, which connects to the Linden Boulevard that runs through Queens. Bending southeast through North Valley Stream, the parkway enters a partial diamond interchange with North Fletcher Avenue (exit 14).
