The Great South Bay Bridge (historically known as the Captree Bridge) is a twin-span bridge on the southwest side of Suffolk County, New York, on Long Island. It carries the Robert Moses Causeway over the Great South Bay, between Long Island's South Shore and Captree Island. It serves as access via the Robert Moses Causeway to both of the downstream crossings, the State Boat Channel Bridge and the Fire Island Inlet Bridge, also leading visitors and on-lookers to the Captree State Park, Fire Island Lighthouse, Jones Beach Island, or Robert Moses State Park. The Great South Bay Bridge also appears on the New York VFR Sectional Chart as a VFR reporting point, under the name Robert Moses Causeway Twin Bridge.
