This tunnel is actually 20kms in length if you don't include a 200 metre open air section on the island of Hundvåg. It then joins with another tunnel which is nearly 6kms length from the island of Hundvåg into Stavanger city centre. So, except the 200 metres where it surfaces on the island of Hundvåg, it's basically a 20km subsea tunnel. But all of those technicalities don't matter when you take into account they are currently busy constructing a 27km (17 mile) and 392 metre-deep tunnel from Stavanger to Bokn. The new tunnel under construction will be the new world's longest and will remove the need for ferry connections on the E39 road from Stavanger to the city of Haugesand - therefore hugely reducing travel time between the two cities. It will be called the Boknafjord Tunnel and is part of the Rogfast project.
Cleaning machines just like with any road. In a tunnel it's even easier because there are no ditches. Traffic accidents by themselves ain't a problem, but fire. This is of course a huge problem, but met by surveillance 7/24 and firing squad on constant alert. There are also security rooms every 250 meters. The biggest problem is probably people not taking fire seriously enough and are too slow to get to one of the secure rooms. You can also choose to get out through the other tube and hitchhike. There are too few people to kill in a tunnel, thus a terrorist would prefer a place with higher concentration. This is why airplanes and tall buildings have been popular.

I worked in this project from 2015 to 2019,but i did'n had the chance to drive when it was finish,it's good to see this video.
Fun fact: In germany the construction would cost 10 billion euros and take 40 years to build.
Here in greece they wouldn't even think about building something like that. i think your country has no need for such long tunnels.
@@questionmark3219 Hey man you say that but you have the Rio-Antirio megabridge, that's some amazing engineering there.
@@questionmark3219 "Greece." LOL! You should have stopped right there! LULZ!
@@JohnVKaravitisGreece truly is the Africa of Europe
I thought Albania was worse than Greece
Awesome video, I love this referent because is very wide and it is actually very practical since it allows cars to go by the undersea tunnel
Good job sir,I have never done tunnel under sea but I appreciated you video.
Good lighting in that tunnel.
wonder how long before the pressure takes over
💀
There is no pressure, it’s located BELOW sea bed
@@alexanderblohme5044 The water pressure will push down on the soil above the tunnel. All that weight displacement has to go somewhere.
@@bobbys4327 well, it’s rock, so I don’t think it will happen anytime soon
as a avvid driver of the tunnel it is ike a plane, it goes after a few minutes and then your ears will equalize
now depends if they make it right it will last 1000 years
They got bathrooms ?Would hate for a bowel movement urge down there
in witch land was this?
Norway.

How do they clean up litter? What if there's a traffic accident? What about terrorist bombs? And so on.

In Stavanger,Norway.
