Sydney's Anzac Bridge is a high-level crossing carrying six lanes of traffic and a combined pedestrian/cycleway. The divided traffic carriageway spans Johnston's Bay, linking Sydney's CBD along the Pyrmont peninsula with Victoria Road and the start of the City West Link at White Bay.
Anzac Bridge is an 805-metre-long concrete bridge replacing a low-level, four-lane steel truss swing span bridge built in 1903 that could not support the increased volume of traffic.
The towers and decking were constructed using concrete incorporating Boral's shrinkage limited cement. Four concrete pumps were used at the height of each pour. With such a large mass of concrete, it was necessary to alleviate any problems caused by differential cooling of the concrete.
The main features of the substructure are the two delta-shaped reinforced concrete towers about 120 metres high.
