Tower Bridge

Tower Bridge is a combined bascule and suspension bridge in London, over the River Thames. It is close to the Tower of London, which gives it its name and has become an iconic symbol of London. Construction started in 1886 and took eight years to build. 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 forces of the suspended sections of the bridge.

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. The bridge's present colour scheme dates from 1977, when it was painted red, white and blue for the Queen's Silver Jubilee. Originally it was painted a chocolate brown colour.
