Sydney harbour bridge

The Sydney Harbour Bridge is one of Australia's most recognizable icons, linking the central business district with the North Shore since 1932.

About this subject

The Sydney Harbour Bridge, opened in 1932, is a steel through arch bridge that spans Sydney Harbour, connecting the central business district (CBD) with the North Shore. With a total length of 1,149 meters and a main span of 503 meters, it was the widest arch bridge in the world until 2012. Its construction required approximately 52,800 tons of steel, much of it produced in England, and involved 1,400 workers, many of whom were immigrants, who faced hazardous conditions over eight years of work.

The bridge is not only a transport route for trains, vehicles, and pedestrians but also a cultural symbol. Since 1998, BridgeClimb has offered the experience of climbing the arch to the summit, 134 meters above sea level, providing panoramic views of the Sydney Opera House and the harbor. On New Year's Eve, the bridge serves as the centerpiece of Sydney's famous fireworks display, attracting millions of spectators.

Notably, the bridge was designed by Scottish engineer John Bradfield, who also oversaw the construction of Sydney's subway system. Originally nicknamed "The Coathanger" for its shape, the structure expands and contracts with temperature changes, varying by up to 18 centimeters. Constant painting is required to protect the steel from salt corrosion: 30,000 liters of paint are needed for each coat, and the process takes 10 years to complete.
