Fehmarnbelt Tunnel

World’s longest underwater rail and road tunnel will connect Germany and Denmark by 2029

Denmark and Germany will soon be linked by an 18-kilometre-long underwater tunnel.

The Fehmarnbelt Tunnel will be the longest combined rail and road tunnel anywhere in the world when it is completed in 2029.

This €10 billion project - which crosses a stretch of the Baltic Sea known as the Fehmarn Belt - will connect Rødbyhavn on the Danish island of Lolland and Puttgarden in northern Germany.

The tunnel, officially called the Fehmarnbelt Fixed Link, will have two double-lane motorways and two electrified rail tracks.

The journey through it will take seven minutes by train and 10 minutes by car, avoiding a 160 kilometre detour across the Danish mainland. Rail travel times from Hamburg in Germany to Copenhagen in Demark will be cut from around five hours to less than three.
