Pyrmont Bridge links Sydney City to Pyrmont and Darling Harbour. It was closed to traffic in 1981 and now carries pedestrian traffic plus the Monorail track.
Construction of the bridge started on 6 September 1899 and the bridge opened on 28 June 1902. It cost 112,500 pounds.
The bridge is 369 metres long. The central span is made of steel but the rest is made from ironbark timber.
The central span pivots and opens to allow ships to pass through. It was the first electrically operated swing bridge in the world.
For smaller ships only the bridge deck swings. For larger ships the monorail track swings also.
It takes 60 seconds to open and is still driven by the original two 50Hp 600V DC General Electric type 57 electric motors.
The bridge has opened almost a million times since it was built.
The central support weighs 6,800 tonnes. It is 13m in diameter and 19m deep.
