Construction of the Fehmarnbelt Fixed Link will take eight and a half years. Here is an overview of the various phases of construction.
Experience the construction project at close hand

We’re building alongside nature
As an addition to the interactive map of the construction sites on both the Danish and German sides, we have now made it possible to get an overview of all the new natural areas that appear around the connection.
Why we're building the Fehmarnbelt tunnel
Denmark’s largest infrastructure project
The Fehmarnbelt tunnel will remove a bottleneck, reduce travel time and strengthen links between Scandinavia and Central Europe.
Time-saving
When the Fehmarnbelt tunnel is completed, the journey between Rødbyhavn and Puttgarden will take 7 minutes by train and 10 minutes by car.
A green shortcut to Europe
The Fehmarnbelt Fixed Link is part of a greener traffic corridor in Europe and will boost the transport of freight by electric trains.
