NJ - Bayonne Bridge
The Bayonne Bridge is the third longest steel arch bridge in the world, and was the longest in the world at the time of its completion--deliberately built two feet longer than the Sydney Harbour Bridge, which opened the year after. Connecting Bayonne, New Jersey with Staten Island, New York, spanning the Kill Van Kull it was built by the Port of New York Authority and opened on November 15, 1931, the bridge was designed by the master bridge-builder Othmar Ammann and the architect Cass Gilbert. Ammann, the master bridge builder and chief architect of the Port Authority, chose the steel arch design after rejecting a cantilever and suspension design as expensive and impractical for the site.
The eventual design of the bridge called for a graceful parabolic arch that soars 226 feet (69 m) above the Kill Van Kull and supports a road bed for 1,675 feet (511 m) without intermediary piers. The total length of the bridge is 8,640 feet (2,633 m) with a mid-span clearance above the water of 150 feet (46 m). The design of the steel arch is based on the Hell Gate Bridge designed by Ammann's mentor, Gustav Lindenthal.
As of 2003, the bridge carried approximately 20,000 vehicles per day.
