London Bridge is a bridge in Lake Havasu City, Arizona. It was originally built in the 1830s and formerly spanned the River Thames in London, England. The bridge was purchased by Robert P. McCulloch from the City of London in 1968. McCulloch had 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. The Arizona bridge is a reinforced concrete structure clad in the original masonry of the 1830s bridge. The bridge was completed in 1971 (along with a canal), and links an island in the Colorado River with the main part of Lake Havasu City. The "rededication" of the London Bridge took place on October 10, 1971.
