The London Bridge is a bridge over the River Thames, between the City of London and Southwark. The current London Bridge was opened in 1973. The previous bridge, built in 1825, was sold in 1970 and moved to Lake Havasu City, Arizona as a tourist attraction (there is some speculation that the purchasers were under the mistaken impression that they were buying Tower Bridge). Before the 1825 bridge, the location was the site of several other historical bridges, going back to the first bridge across the Thames at this site in Roman times.
