The original London Bridge, built in 1830, was slowly “falling down” into the Thames river, unable to handle 21st Century traffic demands.  While still an iconic beauty, the city of London auctioned it off to the highest bidder.  In 1968, the bridge was purchased for $2.4 million by a land developer in Lake Havasu City, AZ.  Over $7 million was spent painstakingly taking the bridge apart, numbering each granite block for exact replacement.  The bridge was rebuilt over a reinforced concrete structure, after which a channel dredged under the bridge was flooded with Lake Havasu’s green water.
