London Bridge (Victoria)

London Bridge is an offshore natural arch in the Port Campbell National Park, Australia. The arch is a significant tourist attraction along the Great Ocean Road near Port Campbell in Victoria. The stack was formed by a gradual process of erosion, and until 1990 formed a complete double-span natural bridge.
The span closer to the shoreline collapsed unexpectedly on the evening of Monday 15 January 1990, sparking comparisons with a well-known nursery rhyme and leaving two tourists stranded on the outer span. They were rescued by police helicopter, and no one was injured in the event.
