Tower Bridge is one of London’s most famous landmarks – but how much do you really know about this architectural oddity? Here are 20 interesting facts about Tower Bridge I’ll bet you never knew.
20 Interesting Tower Bridge Facts
No, Tower Bridge is Not London Bridge
Tower Bridge might be London’s most famous bridge but it’s not London Bridge. London Bridge is a bit further upriver and is pretty plain by comparison.
Over 50 Designs Were Submitted for the Bridge
The City of London Corporation held a competition for the design of a new bridge to help Londoners travel between the two sides of the Thames in 1876.
Over 50 designs were submitted but none were approved.. That’s until 1884 when the final design by architect Sir Horace Jones and civil engineer Sir John Wolfe Barry was picked.
The Same Architect who Designed Tower Bridge also Designed Many of London’s Famous Markets
Sir Horace Jones – the architect behind Tower Bridge shaped some of the most iconic buildings in Victorian London including Leadenhall Market, Smithfield Market and Billingsgate Market.
The Two Levered Sections are Called Bascules
The two sections in the central span are called bascules – and they raise up to an angle of 83 degrees. It’s pretty impressive when you see it. Incidentally, bascule is derived from the French for see-saw – not hard to see why.
And they Weigh Over 1,100 Tons Each
In other words, they’re pretty heavy.
There’s a Huge Chamber Underneath the Bridge to Counterbalance the Bascules
The Bascule Chamber is one of London’s quirkier spots – a huge cavern underneath the bridge in which the counterweights swing to operate the bridge. You can visit on a special tour – but they also have occasional concerts in the chamber as the acoustics are pretty incredible.
It Used to be Powered by Coal Burning Steam Engines
When Tower Bridge first opened, it used to be powered by coal burning steam engines, but these were replaced by a combination of electricity and oil in the 1970s.
Originally Tower Bridge’s Two High Level Walkways Were Created so Pedestrians Could Still Use the Bridge When it was Open
The two high level walkways were designed so that pedestrians would still be able to use Tower Bridge when it was open. However…
The Walkways Fell into Disrepair and Became one of London’s Informal Red Light Districts
The walkways weren’t really used that much… and as a result they became one of London’s informal red light districts, frequented by ladies of the night looking for some custom. They were closed in 1910 but now you can visit them as part of the Tower Bridge Exhibition.
The Facts and Figures Involved in Tower Bridge’s Construction are Pretty Mind-Boggling
Want an idea of how impressive the bridge is? Check out these Tower Bridge facts and figures.
Tower Bridge is made up of more than 11,000 tons of steel and the foundations needed more than 70,000 tons of concrete to support the structure. It also features over 31 million bricks and 2 million rivets.
Tower Bridge once Opened… With a Bus on it
This is hands down my favourite of the Tower Bridge facts I’ve found.
In 1952, a bus driver Albert Gunter was casually driving the 75 bus across the bridge when he noticed something odd happening.
Turns out Tower Bridge was doing what it’s best-known for… starting to open, but with the bus on it. Gunter had to put his foot to the floor and make the bus leap over the opening gap. He made it to the other side, safe and sound and was given the next day off for his bravery and quick thinking. Good old ‘Bertie. What a hero.
A Man Once Parachuted off Tower Bridge to Extol the Benefits of Parachuting
There’s a short film of Thomas Hans Orde-Lees jumping off of the Bridge in 1917 before parachuting safely into the River Thames below. His aim was to show the benefits of RAF pilots using parachutes.
Rather surprisingly, he was successful and the stunt is considered as the momentum for founding the Royal Parachute Regiment. Turns out that people have been pulling stunts on cameras for over a century – Instagram and Youtube didn’t invent it at all!
A Plane Once Flew Between the Bascules and the Walkway
In 1912, a pilot called Frank McClean had to fly his short biplane in between the bascules and the walkways during an emergency. That must have been a close shave.
Tower Bridge Used to be Much Less Colourful
Tower Bridge was painted red, white and blue in 1977 to celebrate the Queen’s Silver Jubilee. Before that it was boring old brown.
It’s since had another major facelift (between 2008 and 2016), which saw it transformed with the gorgeous bright blue and white we see today.
It Took 432 Construction Workers Eight Years to Build Tower Bridge
I’d actually say that’s pretty fast when you look at it. It’s huge.
It Only Takes Five Minutes to Raise the Bridge
Which is kind of impressive when you consider how heavy the bascules are. The bridge is raised through a combination of hydraulic pumps powered by oil and electricity aided by heavy counterweights.
It’s Used by Over 40,000 People Per Day
See – Tower Bridge is not just a pretty face (though it does look rather brilliant too).
Ships have the Right of Way
As long as they have given the folks that operate Tower Bridge over 24 hours notice. Everyone, and that means everyone, has to wait for a ship to pass – even Bill Clinton who famously had to wait for 20 minutes while a barge sailed through in 1997. They don’t care who you are, Tower Bridge is opening for a ship and you will just have to wait.
It was Built to Look Much Older than it Actually is
When many people first see Tower Bridge they think it was built in medieval times but that’s not true. I’m pretty sure no one would want to be walking on a bridge powered by medieval engineering – you can see how it happened though.
The bridge was built to look in keeping with its much older neighbour, The Tower of London, but I suspect the choice of style was also because Victorian’s loved a bit of Neo-Gothic architecture anyway.
Building it Cost a Lot of Money
Building Tower Bridge Cost £1,184,000 at the time, which is the equivalent of a staggering £152,616,515.39 in 2019.
