The Sydney Harbour Bridge is a steel through arch bridge in Sydney, New South Wales, Australia, spanning Sydney Harbour from the central business district (CBD) to the North Shore. The view of the bridge, the Harbour, and the nearby Sydney Opera House is widely regarded as an iconic image of Sydney, and of Australia itself. Nicknamed "The Coathanger" because of its arch-based design, the bridge carries rail, vehicular, bicycle and pedestrian traffic.[1][2]
Under the direction of John Bradfield of the New South Wales Department of Public Works, the bridge was designed and built by British firm Dorman Long of Middlesbrough, and opened in 1932.[3][4] The bridge's general design, which Bradfield tasked the NSW Department of Public Works with producing, was a rough copy of the Hell Gate Bridge in New York City. The design chosen from the tender responses was original work created by Dorman Long, who leveraged some of the design from its own Tyne Bridge.[5]
It is the tenth-longest spanning-arch bridge in the world and the tallest steel arch bridge, measuring 134 m (440 ft) from top to water level.[6] It was also the world's widest long-span bridge, at 48.8 m (160 ft) wide, until construction of the new Port Mann Bridge in Vancouver was completed in 2012.[7][8]
