Fehmarnbelt between Denmark and Germany

The fixed immersed tunnel link across the Fehmarnbelt will be more than 18 km long and carry a four-lane motorway alongside a twin track-electrified railway.

The fixed link will reduce the travel time between Scandinavia and Continental Europe. At a speed of 110 km per hour, this will offer motorists a journey time of approximately 10 minutes through the tunnel. For train passengers, the journey will take seven minutes from coast to coast. The duration of a train journey between Hamburg and Copenhagen will be cut short from about four and a half to merely three hours.

The immersed tunnel solution under Fehmarnbelt is a study in innovative thinking, as it challenges existing tunnel building standards. It improves functionality through its pioneering longitudinal ventilation system and state-of-the-art safety and security features.

The marine construction work has been on-going since 2019 and the impressive work harbour is close to complete. The tunnel element factory is well on the way and the first casting of a tunnel segment will take place around the turn of the year. At the Owners Office in Rødbyhavn and in Burg on Fehmarn there are public exhibitions explaining how the tunnel will be built. 

In close collaboration with Tunnel Engineering Consultants (TEC) and Arup, Ramboll is advising Fehmarn A/S on the design of the immersed tunnel solution.
