Cable stayed bridge in Sydney, Australia

The Anzac Bridge is an eight lane cable stayed bridge that carries the Western Distributor (A4) across Johnstons Bay between Pyrmont and Glebe Island (part of the suburb of Rozelle), on the western fringe of the Sydney central business district, New South Wales, Australia. The bridge forms part of the road network leading from the central business district, the Sydney Harbour Bridge, and Cross City Tunnel to the Inner West and Northern Suburbs.

There were two bridges over Johnstons Bay before the construction of the Anzac Bridge. The first bridge was constructed as part of a project to move the abattoirs out of central Sydney, and to construct public abattoirs at Glebe Island. The first pile of the original bridge was driven in October 1860. The bridge was opened in 1862 and was a timber beam bridge 1045 feet (319 m) long and 28 feet (9 m) wide with a 40 feet (12 m) swing section on the eastern side. It replaced a double steam punt crossing. The bridge was opened to traffic on 3 December 1995 as the Glebe Island Bridge. The bridge was given its current name on Remembrance Day in 1998 to honour the memory of the soldiers of the Australian and New Zealand Army Corps (known as Anzacs) who served in World War I. An Australian Flag flies atop the eastern pylon and a New Zealand Flag flies atop the western pylon. A bronze memorial statue of an Australian Anzac soldier ("digger") holding a Lee–Enfield rifle in the "rest on arms reverse" drill position was placed on the western end of the bridge on Anzac Day in 2000. A statue of a New Zealand soldier was added to a plinth across the road from the Australian Digger, facing towards the east, and was unveiled by Prime Minister of New Zealand Helen Clark in the presence of Premier of New South Wales Morris Iemma on Sunday 27 April 2008.

The bridge is wide and the main span is long. The reinforced concrete pylons are high and support the deck by two planes of stay cables. Initially the stay cables were plagued by vibrations which have since been resolved by the addition of thin stabilising cables between the stay cables. There is a grade separated shared pedestrian footpath and cycleway located on the northern side of the bridge, making possible a walk from Glebe Point Road, down Bridge Road, over the bridge and round Blackwattle Bay back to Glebe Point Road. The bridge can carry a maximum of 180,000 cars per day. It reached its maximum capacity in 2002, only seven years after it was finished and consistent with the principles of induced demand of traffic. Also prior to that date, the bridge had seven traffic lanes (4 eastbound, 3 westbound). Originally, there were bus stops at the western end of the bridge, but they were removed because buses pulling out from the stops created a hazard as they merged with other traffic moving at (or close to) the speed limit. The Australian Anzac statue on the northern side of the bridge is adjacent to the former city bound bus stop; the New Zealand Anzac statue was installed within the ramp area of the former stop on the southern side.
