Fire Island Inlet Bridge

The Fire Island Inlet Bridge, an integral part of the Robert Moses Causeway, is a two-lane, steel arch span with a concrete deck that carries the parkway over Fire Island Inlet.Construction of the Fire Island Bridge was completed in 1964 and although a relatively young structure, (less than 50 years old), its concrete deck has suffered from severe chloride ingress resulting in cracks, spalling, and the formation of potholes.The Fire Island Inlet span of the Robert Moses Causeway connects to Robert Moses State Park on the western tip of Fire Island.The Fire Island Inlet Bridge is located south of the State Boat Channel Bridge, a 665ft long bascule bridge modeled after Brooklyn's Mill Basin Drawbridge.The Fire Island Inlet span cost $10 million to complete and opened to traffic on June 13, 1964. By 1985, a dual span was supposed to be built to alleviate traffic; the second bridge proposal was never implemented. As first proposed in 1938, the span was to be a vertical-lift span with a design similar to that of the Marine Parkway–Gil Hodges Memorial Bridge. The design was changed to conform with that of the Great South Bay Bridge, a 600ft steel-arch span with a 60ft clearance.In 2004, the New York State Department of Transportation began studies on the Fire Island Inlet span after the realization that it was rapidly decomposing due to flaws in the cement during its construction. A 5short ton weight restriction was enforced by local police until permanent repairs could be made.
