On October 10, 1971, London Bridge opened in Lake Havasu City, Arizona. The bridge was originally constructed in 1831 and spanned the River Thames in London, England. By the 1960s, however, the stone structure could no longer safely support city traffic. An American real-estate developer, Robert P. McCulloch, bought the bridge as a tourist attraction and incentive for prospective homeowners in his planned community on the shores of Lake Havasu.

Engineers carefully dismantled the bridge and labeled each piece of masonry. The labeled blocks were then shipped to Arizona. The original stones were fitted like puzzle pieces over stronger material (reinforced concrete) on new bridge.

The new London Bridge was constructed on dry land, with its endpoint on a peninsula jutting into the lake. After the bridge was complete, engineers dug a channel across the peninsula (under the bridge). This created an island, and the London Bridge instantly connected this island to the mainland.
