The Sydney Harbor Bridge is one of the world’s most recognizable landmarks. Not only is it the largest steel arch bridge on the planet, but it also spans one of the globe’s finest natural harbors. Affectionately named the Coathanger by locals, it’s an intrinsic part of the city; you can walk or cycle across it and even climb to its peak for incredible views. The iconic bridge took eight years to build and opened in 1932. It’s made of 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 August 19, 1930, at 10pm.
