There are 26 bridges over the Thames between Teddington and Tower Bridge.
Tower Bridge being the most recognisable of all London’s bridges and is often mistaken for London Bridge. It was opened in 1894 and was the last of the Victorian bridges over the Thames. It was designed by Horace Jones, but Sir John Wolfe Barry, who built it, was the son of Sir Barry Charles, who was the architect of the Houses of Parliament. The towers are linked by twin walkways that closed in 1910, having become a haunt for prostitutes and pickpockets.
It is also London’s only bridge that opens and during the first few years of its life the bridge opened many times a day, but today it needs 24 hours notice. In 1952 a crowded double-decker bus was on the bridge when it started opening and the driver had no choice but to accelerate and jump the gap.
