The Bayonne Bridge is the largest steel arch bridges in the world. It includes Bayonne, NJ, to Staten Iceland, New York City, on. The main purpose of the bridge is to connect the road from Staten Iceland to Manhattan via the Holland Tunnel. At its span measured, it is the fifth largest arch bridge in the world, but like Sydney Harbour Bridge is much wider.
The bridge was designed by Othmar Ammann and the architect Cass Gilbert. It was built by the Port of New York Authority and opened on 15 November 1931.
Ammann chose the steel arch design, having both a hanging as well as a cantilever bridge discarded that would have been too costly and impractical in its intended location. The design of the bridge is a parabolic arch, 69 feet above the Kill Van Kull rises. The total length of the bridge including access ramps to 1762 m ( 5780 ft). The bridge has a span of 511 m (1675 ft) and an average distance of 46 m above the water. The design of the steel sheet was influenced by the Hell Gate Bridge, which was the mentor Ammann, Gustav Lindenthal designed. Construction of the bridge began in 1928. The approximate cost of construction was 13 million dollars.
When it was opened in 1931, it had the longest span of all steel arch bridges in the world. It was intentionally 25 feet (7.62 m) longer than the Sydney Harbour Bridge built, which started before her, but only opened a year later. Because of the Bayonne Bridge of the ferry of the Bergen Point Ferry was discontinued. The road has two lanes in each direction. A pedestrian walkway is currently the only access on foot to Staten Iceland represents the Port of New York Authority also permits bicycle traffic.
With regard to the expansion of the Panama Canal and the associated increase of larger and higher container ships, the Port Authority has decided to raise the roadway deck within the bridge on a clear height of 66 m. The renovation is scheduled to begin in Summer 2013 and completed in time for the expansion of the Panama Canal in 2015.
The bridge was added in 1985 by the American Society of Civil Engineers in the List of Historic Civil Engineering Landmarks.
