Until now, an outer, temporary dike has kept the water out while we built the tunnel entrance – called the tunnel portal. As part of this work, we have established a new permanent dike across the tunnel portal. This made it possible for us to let the water in, which is now covering the tip of the portal area.

The next step is to remove the outer, temporary dike revealing the future coastline with the new dike – a work that is expected to be completed this summer.

"2024 is full of milestones for the project. Nevertheless, it now feels very special that after three years of work we can see a small part of the tunnel where it belongs – under water. Our children, grandchildren and great-grandchildren will take it for granted that you can take a short trip to Germany under the Fehmarnbelt, but for those of us who build it, it is a moving moment," says Morten Kramer Nielsen, Head of Communications on the Fehmarnbelt project.
