Tower Bridge is a combined bascule and suspension bridge over the River Thames. It is close to the Tower of London.
The bridge consists of two towers which are tied together at the upper level by means of two horizontal walkways which are designed to withstand the horizontal forces exerted by the suspended sections of the bridge on the landward sides of the towers.
