Materials used to construct the Sydney Harbor Bridge include: About 6,000,000 steel rivets, 2,800 tons of steelwork, including arch and mild steel approach spans, 122,000 cubic meters of rock was excavated for foundations. 95,000 cubic meters of concrete was used. 17,000 cubic meters of granite facing was used on the pylons and piers. 272,000 liters of paint were used for the initial 3 coats of paint. The span of the bridge was constructed using steel (mostly imported from the UK) with the pylons being constructed from granite and concrete. The deck is asphalt and concrete, and there are two railway lines across on concrete sleepers.
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.
