Construction from 28 July 1923 to 19 January 1932, the Sydney Harbour Bridge is an Australian heritage-listed 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 view of the bridge, the harbour, and the nearby Sydney Opera House is widely regarded as an iconic image of Sydney, and of Australia itself. The bridge is nicknamed “The Coathanger” because of its arch-based design.

The Sydney Harbour Bridge is the sixth longest spanning-arch bridge in the world and the tallest steel arch bridge, measuring 134 m (440 ft) from top to water level. It was also the world’s widest long-span bridge, at 48.8 m (160 ft) wide, until construction of the new Port Mann Bridge in Vancouver was completed in 2012.

The purpose of this photo series from NSW State Archives was to document in photographic form the construction of the Sydney Harbour Bridge from the turning of the first sod and the initial acts of construction to the official opening and early use of the bridge.

The series consists of black and white photographs which were developed from glass negatives and pasted into large albums. One volume is devoted to the southern approach, two to the northern approach and 11 to the main Bridge. Each photograph is captioned and almost all are precisely dated with the caption if the date is not incorporated into the image.
