Tower Bridge has stood over the River Thames in London since 1894 and is one of the finest, most recognisable bridges in the World. It is the London bridge you tend to see in movies and on advertising literature for London. Tower Bridge is the only Thames bridge which can be raised.
Its middle section can be raised to permit large vessels to pass the Tower Bridge. Massive engines raise the bridge sections, which weigh about 1000 tons each, in just over a minute. It used to be raised about 50 times a day, but nowadays it is only raised 4 to 5 times a week.
Tower Bridge is 60 meters long with towers that rise to a height of 43 meters.
