London isn't the only place where you will find the London Bridge. There is also one in Lake Havasu City, Arizona and this is one of the most famous bridges in the country. The name of the bridge comes from the fact that it was originally located in London, spanning the Thames River. The bridge was originally built in 1831, but was dismantled during 1967. The bridge in Arizona is a new, reinforced concrete structure that is surrounded by the original London Bridge's masonry from the 1830s. Robert P. McCulloch is responsible for bringing the exterior granite blocks from London to Arizona.
This famous Florida Bridge is located in Monroe County in Florida. It is responsible for connecting Knight's Key within the Middle Keys with Little Duck Key, which is part of the Lower Keys.
