Tower Bridge is an internationally recognised symbol of London, and the Tower Bridge Exhibition enables you to find out more about the history and operation of this amazing piece of engineering, as well as getting some fabulous views from the upper walkways 140 ft above the Thames. Your visit ends in the original steam engine rooms which powered the bridge until 1976. The bridge was opened in 1894 to relieve the traffic on London Bridge. The bridge lifted 6,000 times in its first year.
Designed by John Wolfe Barry and Sir Horace Jones, its size was governed by navigational requirements. The stonework conceals a steel frame and has no structural function. Today the bridge carries 1,900 vehicles per hour between 7am and 10am and still lifts about 900 times a year for river traffic.
