- Discover how the English Channel Tunnel was built and the engineering challenges of building a 200 kilometer long tunnel underwater.
--
Flanked by two powerful nations, the English Channel has long been one of the world’s most important maritime passages. Yet for most of its history, crossing was a dangerous prospect. Engineers proposed numerous plans for spanning the gap, including a design for an underwater passage more than twice the length of any existing tunnel. Alex Gendler details the creation of the Channel Tunnel.

After spending a semester of my engineering degree studying the construction of the channel tunnel,
I can reveal it was dug by a huge boring machine.
Is that a joke?
Well if its a joke this is a damn good one
Nice

if its sky how it is a tunnel
dont forget to make airproof boring machines so they can bore through the sky safely!

You proposing Amazon Jeff B. starships? I don't think that will work...Elon m.gave his thoughts on and I agree... 🤔
My dad worked on the English side of the tunnel as a civil engineer. He was tasked to deal with the leakage.
how old is your dad ?
@@leaastylez7504 he is 58
He must be proud of his work

Wow...amazing.
I don't get GPS signal in a parking garage and these guys can get an accurate satellite position underground below the seabed?? 3:33
and my gps doesn’t always work properly, with my “location” jumping around the whole street, when testing it in my HOME, next to a window.
EDIT: I forgot to say that the meeting in 2 cm part is even harder...
Do you really believe the general public has the tech? 😂
They didn’t. GPS signal won’t pass trough earth and water, but you can track it outside the tunnel and get a precise direction and distance from that point into tunnel with laser guide.
They are using additional tech to triangulate their position underground
Using a gyrotheodolite?
"Humanity is at their best when breaking down barriers."
Coronavirus: are you sure about that?
We’re not at our best because of these barriers. Coronavirus can easily be dealt if we all work together.
@Ricky you know, ideology...
No little bi***" can't do anything to us if stand together. But not only on a emergency situation, we should stand together for everything like saving the humanity from pandemics to climate crisis.
relax, its just a quote, don't take all literally... gosh, why you people always takes anything so literally
Yes, we can eliminate the pandemic only if medics and Countries will collaborate together and share information
TED-Ed always answers questions i wondered about as a child

Really! Then please mention your answered questions which u had in childhood
Does that confirm when we grow up we actually become like robots that just work eat and sleep without questioning anything ?and when people do for example about the government (covid) we call them conspirator…
Imagine the workers from both the sides met with one worker standing a foot above the other. That would've been such an awkward handshake
Jay Joshi Haha i think they didn't give a fck mate
They would be so happy then notice and be like it was france not our fault! Then the french workers would pull out a stale baget and the british workers would pull out rolls of _aluminium_ foil they duel then after the battle would drink some tea and talk about there exploits the french would proceed to murder the first englishmen that made a "surrender" joke this is about what i think would happen probobky

Imagine if in the faraway future we'll have such a bigass project connecting the US with spain and this happens because one country was not using the metric system

Anglo-French engineering produces some incredible feats when the two sides work together. Such collaborations produced icons such as Concorde, the Channel Tunnel and the Millau Viaduct.
the construction workers who built this tunnel were very brave!! hope the ten who lost their lives rest in peace :(
During construction of the Seikan Tunnel, under the Tsugaru Strait, 34 workers were killed.
@@bjornhebergman8785what does that have to do with the Chunnel? Quit your pity olympics
I love how such a challenging topic has been made interesting with fun graphics and animation. Perfect way to teach and engage at the same time !
Yeah very commendable! I hope i could learn animation too in teaching factual stories .
This seems to be a very impressive place, I hope I can visit sometime in the future when all this is over. Seeing and sharing places like this is why I love traveling and make videos so much! And please keep up the great job!
I love getting informed on such random topics its kind of refreshing.
It would have been good to hear more about the navigation technology that allowed it to work through the rock and water above, rather than just "satellite navigation"
just like egyptians using mirrors for illuminating inside, but these "mirrors" transmited the gps signal outside the tunnel, on both sides, the spot on satellite was on both exists, and the inside of both tunnels was calculated, just like @maxim s. bagaev said
Here is Parliament of India

I wish all my classes were like this. I'd look forward to every single one.
For the first time Im actually pretty early for Ted-Ed like literally I've only seen videos like 5 years ago.
M0rningSc4ree true
The introduction to another related video at the end of this video is smooth and triggers our interest in simply knowing more.
I'm from America and had no idea this even existed, but I'm glad I found out about it; it's amazing!
Haha, of course you are ;)
Every time the machines came close to one another, I held my breath.
STOP TOYING WITH MY EMOTIONS, TEDED!!!
Engineering transforms lives. Respect.
The magnificence of this project doesn't lie in what was accomplished, but in the coming together of people from different lands to build something that benefits everyone. Together we have unlimited potential.
This video was really interesting! Thanks for making it Ted-ed.
It's so entertaining watching this as a student studying civil engineering
That end quote got to me. "Humanity is at their best when we break down barriers." 🙌🥰
I love to watch videos of TED-Ed ,especially when the narrator sounds calm and a voice you'd listen too
Can't agree more about the intro quote. We always come up with intellegent ideas (especially with technology) crazier than what we happen to predict for future.
I did'nt even knew that such a tunnel was possible and that it actually exists. Thank You Ted Ed.
luckily it wasn't built by Elon Musk's Boring company
It took more than 100 Years for British and French to *Trust Each Other*.. Woaaahhhhh...
I mean... have you seen British food? Worse, have you TASTED it?
It takes a long time to get over that and trust people who can stomach such things.
...
Oh yeah, and also a 116-year-long Hundred Years' War, a Nine Years' War, Wars of Spanish and Austrian Successions and a 9-year-long Seven Years' War, not mentioning the centennial Capétien-Plantagenêt dystany conflict (1159-1259), the race for expansion in Africa, the cultural differences stemming from our long shared and conflictual history, or even to this day differing geopolitical strategies and ambitions, but mainly the food thing.
And tea. We will never understand their passion with tea.

Great Video I will show this to my class. Thank you for making the time putting this together.
It's fascinating how they told the story and end with this ending. Clever!
How do you build a tunnel under water? - Do it in the rock beneath the water.
xinyue ma some tunnels are in the sea-bed or river-bed
ive crossed this tunnel in both directions multiple times in my life, and have now only just realised it isnt on the seabed but beneath it. well done me.
This is just the video I needed to keep me awake at 2am.
👏🏽 Job well done Ted-Ed 👏🏽 Job well done 👏🏽
Omg I've never been that hesitant about choosing what video to wtch next!
Hard recommendations...
Pretty decent presentation of the story. One bit you left out is that toward the end of their journey the UK TBMs were driven down into the ground, clear of the tunnel and the French TBMs finished. So, the TBMs didn't meet in the middle like depicted here. Also, the political bit at the end was quite unnecessary.
Richard Forester The political bit at the end was completely out of place, this is a video about engineering, not globalism.
It was perfectly apt. What's your issue exactly?
Agreed. This is about how the tunnel was built, not the creator of the video having a hard-on for so-called refugees. They’re not trying to cross the channel to get to safety - they’re in France, they’re already safe - but because they want the easy benefits and free healthcare of the UK. It’s greed not fear that drives them.
@@firstname405 no it wasn't
@@wertyuiopasd6281 glad to hear you didn't have any issues with it :)
TBM sure is a piece of art. A single piece of equipment capable of digging, transporting, and lining the tunnel. I'd love to be able to see this in person one day.
Omg this is one of my most reoccurring thoughts. Thank you for answering!!
Astounding visuals! I really dig 2:06.. and the other worker animations
Humanity is at its best by breaking down barriers. but those refugees should learn to respect the laws of the land, which they don't.
I enjoy engineering videos a lot and with amazing storytelling plus articulate word play Ted Ed has done it again. 😃💎
Simply astonishing
One of the biggest achievements in human history i guess! This is just something beyond fascinating... To challenge nature and tunnel through the sea... It shows that humans can do most of the things that seem impossible today in the next 100 years...
This is quite true and amazingly fascinating combining, maths, engineering and even physics all together to create a tunnel for the greater good of humanity. Hopefully, we can reflect on this moment and make more things like this such as an elevator to the moon.
Thanks, Chanuth.G

"humany is at theyre best when breaking borders"
UK : BREXIT
LOOL
UK going backwards
@@Yusso seethe more
Ted-Ed seems to be endorsing uncontrolled immigration across the uk border. Dont quite know what it has to do with America but yes let's all get along nicely. Nevermind that any genuine refugees have to pass through all of Europe, and countless safe havens, before they reach England. The people trying to cross are not refugees they are economic migrants. And those borders that apparently need to be broken are the only thing stopping an extremely generous and abusable uk benefits and support system from being completely decimated. Wonder what Americans would think if the British started telling them to erase the Mexican border because 'we're all in it together' and 'yay humanity!'
@@hankjones7054 we do need to enforce borders but honestly the refugee/illegal migrant detainment centers are awful. They literally separate children from their families.there's a better way to detain.

@@BeaverChainsaw I don't understand why you don't just send them back to their countries. Take in thousands of unsurveyed people from developing nations and crime rate, unemployment, and general social unrest will rise. The developing nations lose as well as they're losing workers, it's a lose lose.
Amazing video and great engineering, additionally there are two undersea tunnels in Istanbul called Eurasia tunel (for cars) and Marmarail (a rail rod) that connets Asia to Europe.
I LOVE YOUR VIDEOS FROM THE PAST!!!
that was just the beginning of a great innovated idea
Thanks for educating @ted Ed for educating me and diverting me from studying!
when i was little me and my family went to europe. they said we would go into an underwater tunnel. now i thought we would be in the water and i was so excited! then i realized it was UNDER the water, not under water. i was so disappointed.
I used to think that too lol. I thought it was a literal tunnel through the sea channel. I was shocked when I was kid and found out it was under the sea and not through
This video was very helpful for organizing a huge underwater excavation project for an upcoming plan of establishing an underwater settlement. Well, in minecraft at least. I liked the idea of service tunnels.
i'm in love with the colour palettes of this video
Don't agree with the refugee part but nice video
Hey TED-Ed! Can you please make “Why you should read The Picture of Dorian Gray”. It’s one of my favorite books. Really love your videos.
Skylar Sorrows well until they do. Why don't you tell me. :)
Wow! Great animation! The animation itself being 20th century ideological poster-like conveys the message of the video. This is a great artwork.
Absolutely incredible. I don’t care what you say, humanity is beautiful

@@hermannbarbato globalism is bad... and communism has to be global to work ...

Ted ed What creative way of teaching.Your videos give huge of amount of oppurtunity to study science and other field studying.Finally I wish you Best of all🤗😀💯
Thank you for the tuturial
My dad worked away for weeks and weeks painting the tunnel in the 80s, I was born 83 and I remember he was away quite a long time painting. He told me it was an underwater tunnel and to my 6/7 yrs old brain I asked him how he breathes painting underwater and he told me he had an oxygen tank like a scuba diver! 😂 It made sense to me, he's a cheeky git! He's 66 now.

Not really the same thing, Seikan Tunnel is a bigger tunnel but it's length actually underwater is far less than the Chanel tunnel.
good simple explanation of things. you're analogy at the end there was off place.
That was amazing, but I still more amazed by how we achieve ISS project

I would like to appreciate the fact that Ted-Ed took the time to read and like a bunch of comments.
3:57, did they just shake hands with their left hands?
Could you do a video on Why Yoh Should Read The House of Bernarda Alba by Federico García Lorca. Would love for you to look at the historic inspirations, the fact that this was Federico's last play before he was killed before this was performed, and how it looks at toxic femininity and aggression within a family relationship.
This channels animation and visuals are too good make anything too cool and easy and interesting
i had literally no idea this tunnel existed until I saw this video. cool stuff lol.
I love that quote, “ humanity is at their best when breaking down barriers”. We all share the same planet so let’s make it better for everyone.
IK I will sound like a stickler wehraboo, but the advent of aerial warfare does not suddenly render the English channel a useless means of defense. Ask the Germans how well their aerial assault on the UK went.
I love ❤️ this channel so much!
We are living in tough times.
However, now is the time, more than ever, to believe in yourself, to learn and grow and hopefully become a little wiser.
