November 2004:  Tower Bridge               London, England 
 

Tower Bridge, across the Thames River in London, was completed in 1894.  The framework for the towers is steel, encased in Cornish granite and Portland stone.  It is a double "bascule" bridge, with the roadway leaves raising to allow marine traffic to pass.  At top are the walkways, composed of girders, and are actually cantilever construction.  There is also a suspension component, maintaining the side spans.
