Fifty years ago, on 15 October 1970, Australia's worst-ever industrial accident occurred when the West Gate Bridge collapsed into the Yarra River in Melbourne, killing 35 people.
A point-of-view shot of a tram crossing Princes Bridge towards the city shows Flinders Street Station on the left of the frame, and St Paul’s Cathedral on the right.
This slide shows a plan and two section drawings of the main avenue bridge crossing over the Central and Western Basins and the depth of lake under the bridge.
This clip begins with a panoramic view from the Morehouse Tower of St Paul’s Cathedral looking south over the Yarra River to the Botanical Gardens and the War Memorial.
