About this subject

Tower Bridge, often mistaken for London Bridge, is one of the most recognizable bridges in the world. Located in central London, it spans the River Thames near the Tower of London, from which it takes its name. Construction began in 1886 and took eight years, involving over 400 workers and 70,000 tons of concrete. The design, in Victorian neo-Gothic style, was the work of Horace Jones and John Wolfe Barry.

The bridge's bascule mechanism is a feat of hydraulic engineering originally powered by steam. Today it uses electro-hydraulic systems and pressurized oil. Each bascule leaf weighs about 1,200 tons and takes less than a minute to rise to an 86-degree angle. This movement occurs approximately 800 times a year to allow ships to pass.

The upper walkways, originally open to the public, were closed in 1910 due to lack of use and reopened in 1982 as part of the Tower Bridge Exhibition. They offer panoramic views of the city, and since 2014 a glass floor section lets visitors see the traffic 42 meters below. The bridge is painted in a specific combination of blue and white, which was restored to original colors in 2016.

Culturally, Tower Bridge is a London icon, appearing in films, series, and events like the 2012 Olympics. It also hosts races and celebrations, including the traditional opening for Her Majesty's yacht Britannia. Despite its fame, it remains a functional bridge, with over 40,000 vehicle and pedestrian crossings daily.
