Fehmarnbelt tunnel. Denmark’s largest infrastructure project and the world’s longest immersed tunnel

The Fehmarnbelt tunnel will remove a bottleneck, reduce travel time and strengthen links between Scandinavia and Central Europe. Construction of the Fehmarnbelt tunnel began in 2020 on the Danish side and in 2021 on the German site. The tunnel will be completed in 2029.

Faster journey

When the Fehmarnbelt tunnel is completed, the journey between Rødbyhavn and Puttgarden will take seven minutes by train and 10 minutes by car. Road users and train passengers will save about one hour each way compared to the ferry crossing. The Fehmarnbelt link will be open 24 hours a day as a tunnel is not affected by wind or weather.

First time moving the floating gate

The basins in front of the tunnel factory can be closed at both ends with gates, so that the water level can be raised above sea level when an element has to be sailed out. We were there when the colossal floating gate was moved into place for the first time in the opening to the harbour.
