The Sydney Harbour Bridge is one of Australia's icons, connecting Sydney's central business district to the North Shore since 1932.

About this subject

The Sydney Harbour Bridge is a steel through arch bridge that spans Sydney Harbour, connecting the central business district with the North Shore. Opened on 19 March 1932 after eight years of construction, it was designed by English engineer John Bradfield. With a length of 1,149 meters and a height of 134 meters at its highest point, it was the world's largest steel arch bridge until 2012, when it was surpassed by the Chaotianmen Bridge in China. Its structure uses approximately 52,800 tons of steel, and the arch has a main span of 503 meters.

Nicknamed "The Coathanger" because of its shape, the bridge plays a vital role in Sydney's transport, carrying vehicles, pedestrians, and cyclists. It features eight lanes for road traffic, two railway lines, and a footpath/cycleway. Pedestrian crossing is free, while the "BridgeClimb" experience lets visitors ascend the arch's top for panoramic views of the city and the Sydney Opera House. Approximately 3.5 million people cross the bridge daily.

Culturally, the Sydney Harbour Bridge is a symbol of progress and national identity. It appears in countless films, postcards, and celebrations, such as the New Year's Eve fireworks. Its construction during the Great Depression created jobs and boosted the local economy. In 1980, it was listed as a heritage item by the Australian government. Ongoing maintenance includes continuous painting of the steel structure to protect against salt corrosion, a job that never ends: when painters reach the end, they must start over.
