It carries the West Gate Freeway and is a vital link between the Melbourne central business district and western suburbs, with the industrial suburbs in the west, and with the city of Geelong 80 kilometres to the south-west. It is part of one of the busiest road corridors in Australia. The high span bridge was built to allow large cargo ships to access the docks in the Yarra River.
