A masterpiece of Victorian engineering, this iconic bascule and suspension bridge spans the Thames near the Tower of London, combining Gothic Revival aesthetics with innovative hydraulic mechanics.
At a glance
Tower Bridge is a Grade I listed structure that opened in 1894 to serve the rapidly growing eastern districts of London. Its twin towers and opening bascules remain among the world’s most recognizable bridge forms.
History
By the late nineteenth century, only London Bridge served the densely populated areas east of central London—a single crossing for nearly four million residents. Tower Bridge was conceived to relieve this congestion while preserving shipping access to the Pool of London, the busy anchorage between the Tower and London Bridge.
Construction ran from 1886 to 1894 under the direction of architect Horace Jones and engineer John Wolfe Barry, with assistance from Henry Marc Brunel. Edward, Prince of Wales, and Alexandra, Princess of Wales, formally opened the bridge on 30 June 1894.
What you see
The bridge spans 940 feet and comprises two 213-foot towers connected by high-level walkways. Central bascules open to permit tall vessels to pass into the Pool of London. Originally powered by hydraulic pressure, the operating mechanism was converted to an electro-hydraulic system in 1972.
The towers display Gothic Revival detailing that complements the nearby Tower of London. The bridge deck remains open to traffic and pedestrians; the towers, walkways, and Victorian engine rooms are accessible via the Tower Bridge Exhibition.
Cultural significance
Tower Bridge has become inseparable from London’s identity. Its distinctive silhouette appears in countless photographs and films, occasionally leading to confusion with London Bridge, some 800 metres upstream.
