HISTORY AND FEATURES OF TOWER BRIDGE

Tower Bridge is a combined  bascule and suspension  bridge in London. It is a iconic symbol of London. The construction started in 1886 and took 8 years. It has become 122 years from past to now. 432 construction workers employed. The bridge was officially opened on 30 June 1894 by the Prince of Wales and ,his wife, the Princess of Wales. It is the one of the Trust’s bridges not to connect the City of London directly to the Southwark Bank , as its northern landfall is in Tower Hamlets. The bridge consist of two bridge towers which was tied together at the upper level by two horizontal walkways . The bridge is 800 feet (240 metres) in length with two towers each 213 feet (65 metres) high, built on piers. The main bridge deck carries two lanes of road traffic between two low-level pedestrian walkways across both suspension spans and the opening bascule section of the bridge, with the walkways separated from the roadway by fences. The roadway passes through each of the two towers, whereas the low-level walkways pass around the outside of the towers. The bridge's present colour scheme dates from 1977, when it was painted red, white and blue for Queen Elizabeth II's Silver Jubilee. The bridge deck is freely accessible to both vehicles and pedestrians.
