The Wantagh State Parkway is a 13.33-mile (21 km) long state parkway on Long Island, New York, in the United States. It links the Ocean Parkway in Jones Beach State Park with the Northern State Parkway in Westbury. The parkway is located approximately 30 miles (48 km) east of Manhattan and 14 miles (23 km) east of the Nassau–Queens border. Construction began in 1927 on this, one of the earliest of the Long Island parkways, with the initial 5-mile (8 km) segment opening two years later as the Jones Beach Causeway, connecting Merrick Road in Wantagh to newly opened Jones Beach State Park. The parkway is inventoried by the New York State Department of Transportation (NYSDOT) as New York State Route 908T (NY 908T), an unsigned reference route.
