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 shortcut to Central Europe

The Fehmarnbelt tunnel plays a key role in the future European transport network and will boost the transport of freight by electric trains.
