London Bridge is a bridge in Lake Havasu City, Arizona, United States. It is a relocated 1831 bridge that formerly spanned the River Thames in London, England, until it was dismantled in 1967. The Arizona bridge is a reinforced concrete structure clad in the original masonry of the 1830s bridge, which was bought by Robert P. McCulloch from the City of London. McCulloch had exterior granite blocks from the original bridge numbered and transported to America to construct the present bridge in Lake Havasu City, a planned community he established in 1964 on the shore of Lake Havasu.
