London Bridge (New South Wales)

London Bridge is a limestone karst near Canberra, Australia that consists of a limestone arch hollowed out by Burra Creek, a tributary of the Queanbeyan River of the Molonglo River. It is now isolated as a meander cutoff.

It was first discovered by the European explorers Captain Mark Currie, Brigadier Major John Ovens, Joseph Wild and accompanied by two nameless aboriginal guides in 1822. It was in danger of being flooded by the construction of the London Bridge Dam but owing to its limited catchment, the Australian Government constructed Googong Dam instead. London Bridge is inside a nature reserve and is thus now protected.
