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.
