London Bridge was moved to Lake Havasu City, Arizona, in 1971. Spanning the River Thames, London Bridge was built in 1831. However, by around 1970 the bridge was not structurally sound for modern traffic. The government planned to dismantle it. Robert P. McCulloch, founder of Lake Havasu City, purchased the bridge. The pieces were dismantled, numbered, shipped to Arizona, and reassembled. The bridge, connecting portions of Lake Havasu City, also became a tourist attraction.
