It’s actually really fucking cool, for ones like this they cast them in concrete sections, seal the ends, float them out, and sink them into place! Practical engineering made a video about
My dad’s a retired civil engineer and I got to see how all this worked when he did one back in the day. I got to see the individual sections being built and then got to walk through the tunnel after the sections had been connected and before they were ready for traffic.
This one?

I didn’t know about this tunnel, but I imagine other ones are built by actually digging under ground right?
Different strategies for different situations!
“Hey you!”
Me?
“Yeah you. Get over here and build this tunnel.”
*picks up shovel
Actually not too far from how they built tunnels in the 19th century.
Hmmm… water is leaking in that one, shut it down get out the shovels again and we’ll try to build better one that doesn’t leak.
You there, stick your finger in this dyke!
You can’t just say stuff like that.
The fate of the town depends on it!
It’s only a matter of time before someone has to fly a fighter jet through this to stop a nuke launch.
I imagine lots of people did this in GTA V lol
I’m glad they started putting up No Helicopter signs at the entrance to the tunnel near me. I think the local henchmen got so used to chasing people through them that they would sometimes get distracted and absent mindedly take the tunnel on their commute to work.
That’s the great thing about our species. You never have to do it alone or figure it all out for yourself. Just following instructions will get the job done, and if you contribute an incremental improvement to the process, you’ve gone above and beyond.
It was aliens. We clearly don’t have the technology so the ancient people who created this obviously had external help. Have you seem how huge these blocka are? Insanity.
Easy, you buy a really big machine that goes brrrrrrrrr
For rectangular ones like this they often build it on shore as a big metal tube, and sink it into the water afterwards
Yes the brrrrrrrring machine
Specifically the model that brrrings tunnels to the sea floor.
This machine even is called brrrrrr or borrrrr or something like that.
Fun fact: The word ‘boring’ comes from the tedious work of drilling a hole by hand.
it’s boring work making those tunnels
Stop trying to get out of it and grab a shovel already.
There’s a group in Brooklyn who might be able to help you out
