The Sydney Harbour Bridge is an arch bridge. It is the largest steel arch bridge in the world, measuring 134 metres (429.6 ft) from top to water level, although it is not the longest. Up until 2006, it was also the world's widest long-span bridge, at 48.8 metres wide.

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.

The famous Sydney Harbour Bridge in Australia was constructed on the other side of the world, in Middlesbrough, by local steel giants Dorman Long. The steel used to make it was produced at Skinningrove from local ironstone and the words 'Made in Middlesbrough' are stamped on its side.
