The London Bridge was sinking into the River Thames and available for purchase when McCulloch decided to buy it. Between dismantling the bridge, transporting it to California, trucking it to Havasu, and then reassembling the bridge, it was an engineering miracle. The bridge was dedicated on October 10, 1971, and remains the second-largest tourist attraction in Arizona, next to the Grand Canyon.If you hate wildlife, water, festivals, events, scenery, and architecture, and if you are really trying to avoid fun, then skip this region of southern Arizona. Because traveling Lake Havasu City miles is guaranteed to end in smiles.
