The Fehmarnbelt Tunnel

The Fehmarnbelt Tunnel

The construction of the Fehmarnbelt Tunnel has started in summer 2020. The tunnel will connect Germany (Puttgarden) and Denmark (Rødbyhavn) and create a direct connection between Scandinavia and Central Europe. The tunnel is being built by the Danish state-owned company Femern A/S. Completion is scheduled for 2029.

When completed, the Fehmarnbelt Tunnel will be the longest immersed tunnel in the world and at the same time the longest combined road and rail tunnel.

On this page we would like to give you some information and further links on the tunnel construction as well as current information on the construction sites and the traffic situation.

The Scandlines' ferry service between Puttgarden and Rødbyhavn will continue unhindered throughout the whole construction period.

Information on the German hinterland connection and the planned Fehmarn Sound Tunnel can be found further down on this page.

The German hinterland connection

With the construction of the Fehmarnbelt Tunnel, the so-called hinterland connection will also be expanded. This is intended to ensure the connection on the German side to the tunnel for road and rail traffic. The hinterland connection is also being expanded in Denmark. This is agreed in the state treaty for the Fehmarnbelt Tunnel.

The hinterland connection on the German side comprises three measures: the expansion of the railway line between Lübeck and Puttgarden, a new Fehmarn Sound crossing and the expansion of the road B 207 between Heiligenhafen and Puttgarden.
