The story of the Longest Immersed Tunnel in the World

The Fehmarn Belt Fixed Link will be the longest immersed Tunnel in the world once the construction is completed in 2029. The Fehmarn Belt Tunnel will span a total of 18 km from Rødbyhavn on Lolland (Denmark) to Puttgarden on Fehmarn (Germany).
After the project has been in the planning phase for many decades, the summer of 2020 finally marked the start of the construction.
This video explains the enormous size of the undertaking, the current status of the works and we will explore the impacts that it will have on a local, regional and international level.

Actually the Brenner Base Tunnel is the largest project in Europe now since Cross Rail is finished. Fehmarn is more interesting though.

[@baldurodin2027]

Ja, but the Brenner Pass is under the Brenner in the Alps, not under water, Schorsch mein Junge.

The events of the past few weeks have given me food for thought. After Nord Stream and Crimea one can probably say that a bridge would be much safer. An act of terrorism like the one on the Crimean Bridge would cause a massive catastrophe in a tunnel, even if there were no flooding. The blast would rush through the entire tunnel and cause immense destruction.

Bridges can be hit easily as well. Any enemy capable of blowing a hole in a tunnel under several meters of rock and sand can also blow up bridge pillars using the same methods. The Nord Stream pipes were a lot more vulnerable than this tunnel will be, they are easily accessible by comparison and not compartmentalized in the same manor.

No surprise..... The world we live on (shifts). One inch this way, one inch that way.. (over many years). What yr will be the first crack......? How will they repair the crack..?...pour underwater cement..? Around the world, inside the last thirty years. Installed Natural gas lines are (polyurethane), for that reason. , Polyurethane pipe will not crack.

As someone with an education in structural maintenance I can tell you there is basically nothing to worry about in that regard. This is not a tectonically active area. There are almost never any appreciable shifts in the Danish underground. We have centuries of experience in building structures capable of surviving minor shifts and settling soil. Minor cracks are an inevitability with ALL construction, but with monitoring and repairing they are not an issue or a worry. Again just to really drive the point home, all bridges, tunnels, skyscrapers, monuments and even one story houses will develop cracks over time, this is why we have structural inspections and engineers, their jobs are to recognize and fix these issues as they crop up. If you worry about such things then you shouldn't live in or use any buildings at all.
