The bridge was designed by Sir Horace Jones and engineer John Wolfe Barry to ease road traffic while maintaining access to the busy Pool of London docks.
During the Second World War, the bridge's counterweights were increased to improve the speed of the bascule operation in case of damage.
The high-level walkways were closed to the public from 1910 until 1982 because they became havens for pickpockets and prostitutes.
The bridge is painted its iconic white and blue colors to commemorate the Queen's Silver Jubilee in 1977; it was previously painted a chocolate brown.
A bus once famously jumped the gap while the bridge was opening in 1952 when the driver accelerated to clear the rising span.
The bridge's hydraulic system was originally powered by coal-fired steam engines that produced enough pressure to move the massive counterweights in under two minutes.
The glass floors in the high-level walkways are 65mm thick and can support the weight of an elephant.
Tower Bridge is often confused with London Bridge, which is located approximately 0.8 kilometers upstream.
Tower Bridge is a combined bascule and suspension bridge spanning the River Thames, constructed between 1886 and 1894. The structure features two Victorian Gothic towers connected by high-level walkways, which originally served as pedestrian crossings. The bridge employs a hydraulic system, now powered by electricity, to lift the 1,100-ton bascules for river traffic. The high-level walkways feature glass floors, offering a view of the roadway and river traffic 42 meters below. Visitors can access the Victorian engine rooms to view the original steam-powered machinery used to operate the bascules. The bridge is a functioning piece of maritime infrastructure and a protected Grade I listed building. It stands as a distinctive example of 19th-century civil engineering and ornamental ironwork.
Potters Fields Park on the south bank provides the most balanced perspective of both towers and the central span.
Check the official bridge lift schedule online before your visit to ensure you see the bascules in action from the pedestrian walkway.
Visit the engine rooms after exploring the high-level walkways to understand the historical steam technology.
Combine your visit with a walk along the Thames Path for varied angles of the Victorian towers.
Do not attempt to drive across during peak commuting hours if you are on a tight schedule, as traffic can be significant.
The bridge occasionally closes to pedestrians and vehicles for planned maintenance or special events; check the official website for real-time status alerts.
