How long is the longest underwater tunnel?
Whats the length of the longest underwater tunnel in the world?
Okay, so longest underwater tunnel, huh? My brain's kinda fried trying to remember all this stuff. But eighteen kilometers? That's…wow. Seriously long. I read about that Fehmarn Belt thing ages ago – think it was sometime in March last year, flicking through a magazine at the dentist's.
Road and rail? Under the water? That's insane engineering. I mean, I've seen some pretty impressive bridges, but a tunnel that deep, that long… I can barely imagine the logistics. The cost must be astronomical!
The article mentioned something about it connecting Germany and Denmark. Makes sense, geographically. I'm picturing all those trucks and trains rumbling through, beneath the sea. Pretty wild.
Fehmarn Belt fixed link. 18 kilometers. Longest underwater tunnel, apparently. Deepest, too. That's what I gleaned, anyway. Hope I'm not totally off base.

Longest tunnel? Underwater? Is it Fehmarn Belt Fixed Link? Yah, that's it! Germany to Denmark. Wow.
Wait, how long is it actually? And 7 minutes by train? Seriously?
- Road and rail tunnel
- Connects Denmark and Germany
- $8.7 billion. that's insane.
Travel time: Train (7 mins), car (10 mins). Makes me wonder about construction costs. Is that typical?
My Aunt Carol lives near Hamburg. I should tell her about it; maybe she will drive to Copenhagen.
- World's longest underwater road and rail tunnel
It seems a long time to plan and make. How do they even do it? Imagine being inside the tunnel. It must be scary.

Ah, the Lærdalstunnelen! A name that rolls off the tongue like a rogue marble. It's the world's longest road tunnel, clocking in at a hefty 24.5 km. Imagine the audiobooks you could plow through!
Opened back in November 2000, this Norwegian marvel connects Aurland and Lærdal. Lighting? Oh, it's not just some bare bulb situation. Think fancy rock chambers every 6 km, all jazzed up. It's like a rave in a mountain… but safer. Well, mostly.
- It's in Norway, obviously. Land of fjords and expensive sandwiches.
- The purpose? To provide a winter-free road connection between Oslo and Bergen. Because who wants to drive over a snowy mountain? Not me.
- Special lighting! It keeps you awake, allegedly, and prevents that "tunnel hypnosis" thing. Like driving into infinity with a bad soundtrack!
- Opened in 2000, making it, like, ancient by tech standards. Still impressive, though.
- I once tried to pronounce "Lærdalstunnelen" five times fast. Do not recommend. It's a tongue twister from... well, Norway. Duh!
There are longer tunnels if you count rail tunnels, but this is the longest road tunnel. Like the difference between a Chihuahua and a Great Dane. Both dogs, wildly different lengths.
Which is the longest tunnel in the world?
Man, that Gotthard Base Tunnel in Switzerland, right? Crazy long. I was there in 2022, July, I think. Hot as hell, even in the tunnel. Air conditioning? Forget about it! Seriously though, 57 kilometers! My jaw dropped. It felt endless.
It's a railway tunnel. Trains whooshing by, this crazy deep rumble. The scale is just unbelievable. Pictures don't do it justice. I mean, seriously, you’re underground for what feels like forever. Claustrophobic? A little. But mostly, awestruck.
That Seikan Tunnel in Japan? Heard it’s pretty impressive too, but it's shorter, obviously. The Gotthard totally beat it. Longest. Railway. Tunnel. Period. Road tunnels? The Lærdal Tunnel in Norway is the champ there. Still, nothing compares to the Gotthard.
The sheer engineering is astounding. I'm not an engineer, but still, wow. I felt so small, you know? Insignificant. Next to something so huge. Took a bunch of photos, of course. Wish I could've spent more time in the Swiss countryside afterwards, but train schedule and all that. Next time!
- Gotthard Base Tunnel (Switzerland): 57.1 km (Longest railway tunnel)
- Seikan Tunnel (Japan): Shorter now!
- Lærdal Tunnel (Norway): 24.51 km (Longest road tunnel)
The sheer magnitude of these things. Makes you rethink everything. Travel is great!
