The largest steel arch bridge in the world, the Sydney Harbor Bridge is an iconic landmark spanning one of the finest natural harbours known to mankind. Opened in 1932, the bridge is fondly nicknamed the Coat Hanger by Sydneysiders. You can walk and cycle across the bridge or climb to the top for stunning views.The iconic bridge took eight years to build using 53,000 tonnes of steel and six-million hand-driven rivets. During construction, the two steel halves of the towering arch met in the middle of the span on 19 August 1930 at 10pm. The arch spans 1,650 feet and the top is 439 feet above the water.
