Tower Bridge, the symbol of London

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.
