This place is a bridge connecting the Sydney CBD and North Shore. The bridge was nicknamed 'The coat hanger' special features views of the harbor and the SydneyOpera House.
The Sydney Harbour Bridgeis a steel through arch bridge across Sydney Harbour that carries rail, vehicular, bicycle and pedestrian traffic between the Sydney central business district (CBD) and the North Shore. The dramatic view of the bridge, the harbour, and the nearby Sydney Opera House is an iconic image of Sydney, New South Wales, and Australia. The bridge is nicknamed "The Coathanger" because of its arch-based design.
Under the directions of Dr J.J.C. Bradfield of the NSW Department of Public Works, the bridge was designed and built by British firm Dorman Long and Co Ltd of Middlesbrough and opened in 1932.The bridge's design was influenced by the Hell Gate Bridge in New York. It is also the sixth longest spanning-arch bridge in the world, and it is the tallest steel arch bridge, measuring 134 metres (440 ft) from top to water level.It was also the world's widest long-span bridge, at 48.8 meters (160 feet) wide, until construction of the new Port Mann Bridge in Vancouver.The Road
From the Sydney CBD side, motor vehicle access to the bridge is normally via Grosvenor Street, Clarence Street, Kent Street, the Cahill Expressway, or the Western Distributor. Drivers on the northern side will find themselves on the Warringah Freeway, though it is easy to turn off the freeway to drive westwards into North Sydney or eastwards to Neutral Bay and beyond upon arrival on the northern side.
The bridge originally only had four wider traffic lanes occupying the central space which now has six, as photos taken soon after the opening clearly show. In 1958 tram services across the bridge were withdrawn and the tracks replaced by two extra road lanes; these lanes are now the leftmost southbound lanes on the bridge and are still clearly distinguishable from the other six road lanes. Lanes 7 and 8 now connect the bridge to the elevated Cahill Expressway that carries traffic to the Eastern Distributor.
In 1988, work began to build a tunnel to complement the bridge. It was determined that the bridge could no longer support the increased traffic flow of the 1980s. The Sydney Harbour Tunnel was completed in August 1992. It is intended for use only by motor vehicles.
The Bradfield Highway is designated as a Travelling Stock Route which means that it is permissible to herd livestock across the bridge, but only between midnight and dawn, and after giving notice of intention to do so. In practice, owing to the high-density urban nature of modern Sydney, and the relocation of abattoirs and markets, this has not taken place for approximately half a century.
