Tower Bridge

This is an iconic view of the Tower Bridge, easily one of London's most recognized landmarks. It is designed as a suspension bridge at its extremities and a bascule (lift) bridge in the centre portion to allow for Thames River boat traffic to pass.

 

Tower Bridge was built over 120 years ago to ease road traffic while maintaining river access to the busy Pool of London docks. Built with giant moveable roadways (bascules) that lift up for passing ships, it is, to this day, considered an engineering marvel and beyond being one of London’s favourite icons, it is arguably one of the most famous and instantly recognisable structures in the entire world.

 

It took eight years, five major contractors and the relentless labour of 432 construction workers each day to build Tower Bridge.

Two massive piers were sunk into the river bed to support the construction and over 11,000 tons of steel provided the framework for the Towers and Walkways. This framework was clad in Cornish granite and Portland stone to protect the underlying steelwork and to give the Bridge a more pleasing appearance.

 

1910 - the high-level Walkways, which were designed so that the public could still cross the bridge when it was raised, were closed down due to lack of use.

1912 - during an emergency, Frank McClean had to fly between the bascules and the high-level walkways in his Short biplane, to avoid an accident.

1952 - a London bus driven by Albert Gunter had to leap from one bascule to the other when the bridge began to rise with the number 78 bus still on it.

1977 - Tower Bridge was painted red, white and blue to celebrate the Queen's Silver Jubilee. (Before that, it was painted a chocolate brown colour).

1982 - Tower Bridge opened to the public for the first time since 1910, with a permanent exhibition inside called The Tower Bridge Experience.

 

Since 1982, visitors have been able to see inside Tower Bridge and discover the history of the bridge and why it came into existence through fascinating exhibition content. Visitors can also experience the exciting new glass floor and spectacular panoramic views from the high-level Walkways as well as the Victorian Engine Rooms, which house the beautiful steam engines that once powered the bridge lifts until 1976. In 1976, Tower Bridge switched from steam power to electricity and hydraulics.

 

Under the Corporation of London (Tower Bridge) Act 1885, the City of London Corporation is required to raise the Bridge to provide access to and egress from the Upper Pool of London for registered vessels with a mast or superstructure of 30 feet or more. The service is provided free of charge subject to 24 hours’ notice and is available any time, day or night, 365 days per year. The Bridge is raised around 850 times each year.
