In this video, Minutephysics gives a great little history of London bridges, including the one purchased in the late 1960s by entrepreneur Robert P. McCulloch from the City of London and rebuilt in Lake Havasu City, Arizona, where it stands today. McCulloch bought the bridge to attract tourists to Lake Havasu City (a city he founded) and there is an urban legend that says he thought he was buying the Tower Bridge (which many still mistake as the London Bridge).
