Surrounded by faked-up Tudor buildings and busloads of tourists, the large bridge is dwarfed by the majesty of the desert Southwest. The entire enterprise stands as a monument to a deep human appreciation for irony, for what else could explain the immense cost and energy that went into transporting such an immense structure such a long way for so very little purpose. But this peculiar structure in the desert is in fact not the real London Bridge at all (if any bridge can in fact lay claim to that title, which seems unlikely), but the New London Bridge, designed in 1831 by the Scottish engineer John Rennie

It might be hyper-modern, a strong, sound construction of metal designed tolast millennia rather than centuries, clean-limbed, flaunting the ribs andtransoms of its construction.

Problems in maintaining a sufficiently highlevel of watertight-ness were caused by both the natural forces of erosionworking on the stone and the vibrations from heavy traffic across thebridge and prompted many of the repairs that the bridge was subjected toduring its lifetime, and it was the continual deterioration of its pieragesthat prompted it to be replaced by New London Bridge.
