About the Fehmarnbelt Tunnel

The Fehmarnbelt Tunnel, also called the Fehmarnbelt Fixed Link, is a 17.6km (10.9-mile) road and rail tunnel that will connect the Danish island of Lolland with the German island of Fehmarn. The tunnel will traverse underwater through the Fehmarn Belt in the Baltic Sea.

Once connected, the line will run to Denmark鈥檚 Zealand Island and eventually to Copenhagen on the Danish mainland. Once complete, it will be the world鈥檚 longest road and rail tunnel and will shorten the trip from Lolland to Fehmarn from 45 minutes (by boat) to ten minutes by car and seven minutes by rail.

Construction of the Fehmarnbelt Tunnel near Puttgarden began 15 April of this year.

The tunnel is expected to cost 鈧�7 billion (US$8.2 billion) and open in 2029.
