__ The Sydney Harbour Bridge __

The Sydney Harbour Bridge, also affectionately known as the 'Coathanger', was opened on March 19th 1932 by Premier Jack Lang, after six years of construction. Made of steel the bridge contains 6 million hand driven rivets. The surface area that requires painting is equal to about the surface area of 60 sports fields. The Bridge has huge hinges to absorb the expansion caused by the hot Sydney sun. You will see them on either side of the bridge at the footings of the Pylons.

The Sydney Harbour Bridge is the world's largest steel arch bridge.

After inviting worldwide tenders in 1922, the New South Wales Government received twenty proposals from six companies and on 24 March 1924; the contract was let to the English firm Dorman Long and Co of Middlesbrough.

The foundations for the four main bearings, which carry the full weight of the main span were dug to a depth of 12.2 metres and filled with special reinforced high-grade concrete laid in hexagonal formations. media type="custom" key="11199924" width="160" height="160" The opening celebrations included a vast cavalcade of decorated floats, marching groups and bands proceeding through the city streets and across the deck in a pageant of surprising size and quality, considering the economic depression. The celebrations continued with a gun-salute, a procession of passenger ships under the Bridge, a 'venetian' carnival, a fly-past, fireworks, sports carnivals and exhibitions. After the pageant the public was allowed to walk across the deck…an event not repeated until the 50th anniversary of the Bridge in 1982. media type="custom" key="11721904" align="left"
