Arch bridges are one of the world's most ancient bridge forms. The arch gives the bridge its essential strength. Between the engineer of the Sydney Harbour bridge, Ralph Freeman, and the designer, JCC Bradfield, this was seen as the best option for the purpose.
Freeman felt that since the purpose of the bridge was to cross a wide harbour which often saw some fairly wild weather, the arch shape would be the most stable.
Originally, the bridge's designer, JCC Bradfield, proposed a suspension bridge, then a cantilever bridge, which was the first proposal accepted. After that, Bradfield turned his sights towards an arch bridge, after travelling overseas and seeing the developments in light steel which made a steel arch bridge such a possibility.
It is called that because it crosses over the Sydney harbourBecause it's a bridge in Sydney over the harbour.
