London Bridge is a bridge in Lake Havasu City, Arizona. United States. When it was built in the 1830s, it spanned the River Thames in London, England. In 1968, the bridge was purchased from the City of London by Robert P. McCulloch. However, McCulloch only had the exterior granite blocks from the original bridge cut and transported to the United States for use in the construction of a new bridge in Lake Havasu City, a planned community he established in 1964 on the shore of Lake Havasu.
