The Sydney Harbour Bridge is a steel arch bridge across Sydney Harbour that carries rail, vehicular and pedestrian traffic between the Sydney central business district (CBD) and the North Shore. The dramatic view of the bridge, the harbour, and the nearby Sydney Opera House is an iconic image of both Sydney and Australia. The bridge is locally nicknamed "The Coathanger"or "Colin"[1] because of its arch-based design.
The bridge was designed and built by Dorman Long and Co Ltd, Middlesbrough Teesside and Cleveland Bridge, Darlington, County Durham and opened in 1932. Until 1967 it was the city's tallest structure.[citation needed] According to Guinness World Records, it is the world's widest long-span bridge[2] and its tallest steel arch bridge, measuring 134 metres (429.6 ft) from top to water level.[citation needed] It is also the fourth-longest spanning-arch bridge in the world.
There had been plans to build a bridge as early as 1815, when Francis Greenway proposed that a bridge be built across the harbour. Nothing came of this.
By 1900, a competition was launched to find a suitable design. There were many entries, but none were accepted due to low standards.
Designs and proposals were requested in 1900, but a formal proposal was not accepted until 1911. In 1912, John Bradfield was appointed chief engineer of the bridge project, which also had to include a railway. After travelling extensively to look at a number of bridges worldwide, he based his idea upon New York City's Hell Gate Bridge. Bradfield completed a formal design for a single arch bridge in 1916, but plans to implement the design were postponed until 1922, primarily because of World War I.
In 1923, 800 homes and a high school campus were demolished in preparation for construction. The owners of these homes received compensation, but their occupants did not.
The building of the bridge was under the management of Bradfield. Three other people were involved in the bridge's design and construction: Laurence Ennis, the engineer-in-charge at Dorman Long and Co was the main supervisor (Bradfield visited occasionally throughout the project and, in particular, at the many key stages of the project, to inspect progress and make managerial decisions); Edward Judge was chief technical engineer of Dorman Long and later became president of the British Iron and Steel Federation; Sir Ralph Freeman was hired by the company to design the accepted model in further detail. Later a bitter disagreement broke out between Bradfield and Freeman as to who actually designed the bridge. Another name connected with the bridge's design is that of Arthur Plunkett.
The official ceremony to mark the "turning of the first sod" occurred on 28 July 1923. This was followed by the building of two worksheds at Milsons Point to assist in building the bridge—the light and heavy workshops[citation needed]. Their purpose was to build the bridge's many parts.
