Just yesterday B1M published an interesting video about the future longest tunnel between Lyon, France and Turin, Italy. It will be more than 50km, deeply below the Alps. The project has finally secured funding, from both countries and EU, and is on track.

- sofixa 10mo agoIt would be brilliant. Currently the Paris-Milan train line is barely competitive with flying between the two; knocking off 2-3 hours from the trip would make it around 4 hours in total, which is very competitive with flying (1h30 flight, but both CDG and Malpensa are big airports far outside the city, with significant time wasted getting to them, through security, etc). And of course it would be massive for Lyon - Turin, and Lyon - Milan too, where flying wouldn't even make sense any more.

- ChrisMarshallNY 10mo agoIsn't Italy a little geologically unstable? I'd be a bit nervous, going through a long tunnel, in a region known for vulcanism and earthquakes.
- AnimalMuppet 10mo agoIt is unstable, but (I think) more so in the south. I'm not sure that the Alps region is unstable.
- whizzter 10mo agoItaly isn't a puny country, it's over 1000kms between Sicily and the Alps (Like LA to Albuquerque), seems the fault lines reaches northern Italy (about 100km from the alps) but the amount of larger quakes seems smaller there.
- eCa 10mo agoThe 57 km Gotthard Base Tunnel has been in operation since 2016. There's also a 3km long tunnel between France and Italy that opened in 1882. Nowadays there's probably hundreds of 1km+ tunnels in the Alps.
- ChrisMarshallNY 10mo agoWell, from the other responses, it seems the Italian Alps are pretty stable.
- tacone 10mo agoYes but we're drilling holes through them to fix that.
- gunzel412 10mo agoLet me introduce you to the Seikan Tunnel [1] between the islands of Honshu and Hokkaido in Japan, 53.85km with 23.3km of that under the sea. [1] https://en.wikipedia.org/wiki/Seikan_Tunnel https://en.wikipedia.org/wiki/Seikan_Tunnel
- ChrisMarshallNY 10mo agoNow, that’s scary. I do know that the Japanese have the world’s best anti-earthquake architecture (because they need it), but it’s still scary.
