The Bridge

The Sydney Harbour Bridge has become one of the world’s most iconic bridges and a symbol both of Sydney and Australia. It was constructed by the British firm, Dorman Long & Co., with Sir Ralph Freeman, of Freeman Fox & Partners, carrying out the detailed design work. The initial design by John Bradfield had specified a cantilever design but advances in steelmaking enabled the redesign as a less expensive steel-arch bridge.

The bridge would have to carry the heavy loads of rail and road across the deep waters of the harbour to the new suburbs to the north. The population was growing fast and the new connection was vital to the city.
It was constructed out from each bank and connected in the middle in 1930. Its 503m central span makes it one of the longest bridges of its type in the world.
