Heritage listing thumb|The Harbour Bridge is an important aspect of Sydney's cultural and architectural heritage. At the time of construction and until recently, the bridge was the longest single span steel arch bridge in the world. 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.
