Historical information
London Bridge, pre 1990 was a double-spanning bridge connected to the mainland. The stack was created over hundreds of years, with the weaker layers toward the base being eroded away by wind and water to form the two bridges. The span closer to the shoreline collapsed unexpectedly on 15 January 1990, leaving two visitors, whilst uninjured, stranded on the outer span before being rescued by helicopter.
Physical description
Two coloured photographs of the London Bridge, on the Great Ocean Road. This photo was taken days before the collapse of the geological feature. The photographer walked across the bridge to the warning of her mother "if you go over there and it collapses you will be stuck. After the collapse it was renamed London Arch.
