The Iron Cove Bridge is a heritage-listed road bridge that carries Victoria Road (A40) across Iron Cove, linking the Sydney suburbs of Drummoyne to Rozelle in the City of Canada Bay local government area of New South Wales, Australia. Current bridges A decision to replace the original bridge was made in 1939 just prior to the outbreak of World War II. Design work began in 1942 and construction by Hornibrook McKenzie Clarke Pty Ltd commenced in 1947. The bridge was officially opened by the Hon. J.J. Cahill, MLA, Premier and Colonial Treasurer of NSW on 30 July 1955. Designed by Laurie Challis from the NSW Department of Main Roads, the Iron Cove Bridge is an impressive steel truss bridge. It consists of four plate girder approach spans and seven steel Pratt truss spans for a total length of . Four lanes of traffic are located within the truss spans and the overall width of the roadway is between kerbs. The roadway consists of a reinforced concrete deck slab with an inset for tram tracks in the centre portion. The bridge has aesthetically distinctive piers and abutments which reflect the Inter-War Art Deco style. Furthermore, it was the last steel truss bridge to be constructed in New South Wales in which rivets were used for field connections prior to the introduction of high strength bolts. The bridge was built to carry four lanes of traffic, however a fifth lane was later added to the southwest side of the bridge. This extra lane ran outside of the main bridge supports, forcing traffic to remain in the lane for the length of the bridge. Until the bridge duplication completed in 2011, the default configuration was three westbound and two eastbound lanes, switching to two westbound and three eastbound lanes during the morning peak. Bridge duplication In April 2009, the NSW Government approved plans to construct a second bridge over Iron Cove as part of the Inner West Busway along Victoria Road. During the proposal phase there were strong protests against the duplicate bridge being built from local residents as well as both local area councils of the City of Canada Bay (Drummoyne side) and Leichhardt (Rozelle side). Local residents within both Drummoyne and Rozelle formed the Victoria Road Community and organised public demonstrations, the last of which on 29 March 2009 attracted over 3000 protest marchers. Opposition to the new bridge was based
