The Sydney Harbour Bridge

The dominating Sydney Harbour Bridge was officially opened on 19 March, 1932. Plans for a crossing at Sydney Harbour had been hotly debated since 1815, when businesses desperately sought a faster way to transport goods across the waters. Proposals for various bridges and tunnels came and went, but it wasn't until 1923, more than a hundred years later, that construction began on what would be a masterpiece of engineering. The final design by John Bradfield was spectacularly ambitious, based on New York City's Hell Gate Bridge, and would take nearly eight years to complete.

The English steel maker, Dorman Long & Co was contracted to build the Harbour Bridge. In those days, safety standards were poor, and thousands of workmen risked their lives to construct the bridge, which, at 52,800 tonnes, required six million rivets to be heated and hand-driven into place. Sixteen workers were killed during the grueling construction, although remarkably, only two actually fell from the bridge. The final cost was over £10 million - which was double the original quote. It was not paid off in full until 1988.

The arch-based design makes it the world's largest steel arch bridge at 134 metres above the harbour. It is also the fourth longest-spanning arch bridge at 503 metres, just one metre short of the Bayonne Bridge in New York. The Sydney Harbour Bridge connects Dawes Point in the Sydney Rocks area to Milsons Point on the North Shore, carrying eight traffic lanes, two train tracks, a bicycle path and a footpath. There is a toll for southbound traffic into the Central Business District.
