Bridge Building
The most famous bridge ever constructed by a Teesside company was Dorman Long's Sydney Harbour Bridge of 1932. This was partly modelled on the 1928 Tyne Bridge, a construction regarded as the symbol of Tyneside's Geordie pride, but also a product of Dorman Long's Teesside workmanship. The greatest example of Dorman Long's work in Teesside itself is the single span Newport Lifting Bridge (a Grade II Listed Building). Opened by the Duke of York in February 1934 it was England's first vertical lift bridge. With a lifting span of 270 feet (82 m) long by 66 feet (20 m) wide, it is constructed from 8000 tons of Teesside steel and 28,000 tons of concrete with towers 182 feet (55 m) high. The electrically operated lifting mechanism allowed the road to be lifted 100 feet (30 m) in one and a half minutes by means of ropes passing through sheaves in the four corner towers. Newport Bridge is no longer raised or lowered; it is a permanent road crossing the river Tees.
The following is a list of some of the bridges built by the Dorman Long: it is not fully comprehensive.
