London Tower Bridge, an iconic symbol of London, is a combined bascule and suspension bridge in London on the Thames River.
Built between 1886 and 1894, the bridge consists of two towers tied together at the upper level by means of two horizontal walkways, designed to withstand the horizontal forces exerted by the suspended sections of the bridge on the landward sides of the towers. The vertical component of the forces in the suspended sections and the vertical reactions of the two walkways are carried by the two robust towers.
The bascule pivots and operating machinery are housed in the base of each tower.
