Why is the Sydney harbour bridge called Sydney harbour bridge?
Arch bridges are one of the world's most ancient bridge forms. The arch gives the bridge its essential strength. Between the engineer of the Sydney Harbour bridge, Ralph Freeman, and the designer, JCC Bradfield, this was seen as the best option for the purpose. Freeman felt that since the purpose of the bridge was to cross a wide harbour which often saw some fairly wild weather, the arch shape would be the most stable. Originally, the bridge's designer, JCC Bradfield, proposed a suspension bridge, then a cantilever bridge, which was the first proposal accepted. After that, Bradfield turned his sights towards an arch bridge, after travelling overseas and seeing the developments in light steel which made a steel arch bridge such a possibility.
What date was Sydney Harbour Bridge completed and opened for traffic?
Sydney Harbour Bridge was opened to traffic on 19 March 1932. The bridge was built to connect the Sydney CBD with the North Shore commercial and residential areas on Sydney Harbour. Prior to this, the closest crossing was much further upstream. In 1912, John Bradfield was appointed chief engineer of the bridge project, which also had to include a railway. Plans were completed in 1916 but the start of World War I delayed implementation until 1922. Construction of the bridge began in 1924, and took 1400 men eight years to build at a cost of £4.2 million. See the related link for more information.

Why is the harbor bridge famous?
The bridge is one of the most remarkable feats of bridge construction. The bridge, its pylons and its approaches are all important elements in townscape of areas both near and distant from it. The curved northern approach gives a grand sweeping entrance to the bridge with continually changing views of the bridge and harbour. The bridge has been an important factor in the pattern of growth of metropolitan Sydney, particularly in residential development in post World War II years. In the 1960s and 1970s the Central Business District had extended to the northern side of the bridge at North Sydney which has been due in part to the easy access provided by the bridge and also to the increasing traffic problems associated with the bridge (Walker and Kerr 1974). The reputation of the Sydney Harbour Bridge as the world's greatest steel arch rests on its combination of span, width and load bearing capacity, and for the difficulties overcome in its erection. (Sydney Harbour Bridge Conservation Management Plan, p.vii, RTA 1998) The Sydney Harbour Bridge has been assessed as being of State significance.
