The State Boat Channel Bridge is a twin-span bascule bridge in Suffolk County, New York, United States. It carries the Robert Moses Causeway over the Long Island New York State Boat Channel between Captree Island and Jones Beach Island, in Oak Beach and Captree on the Babylon–Islip town border.

Description

The 665 ft bascule bridge meets the Ocean Parkway at a cloverleaf interchange. This interchange, which provides access to Captree State Park, Gilgo State Park and Jones Beach State Park, served as the southern terminus of the Robert Moses Causeway that leads to the Fire Island Inlet Bridge, the Fire Island Lighthouse, and Robert Moses State Park. The bridge underwent renovations during the 2000s.
