Tunnel Fehmarnbelt – Combined (road-rail)

Reference: Fehmarnbelt

The Fehmarnbelt tunnel will be the world’s longest of its type for both road and rail.

The Fehmarnbelt link will be built as an immersed tunnel between Rødbyhavn on Lolland and the German island of Fehmarn. In contrast to a bored tunnel, an immersed tunnel is made up of hollow concrete elements, cast on land and assembled section by section to form the tunnel.

The tunnel will consist of 79 individual elements, each 217 metres long, and 10 special elements with a lower floor for the use of the tunnel operation and maintenance equipment.

A trench for the tunnel must first be dug in the seabed in order to build the Fehmarnbelt link. This trench will be up to 60 metres wide, 16 metres deep and 18 kilometres long. In total, some 19 million cubic metres of stone and sand will be excavated from the seabed. This will be used to establish approximately three square kilometres of new natural areas on Lolland and, to a lesser extent, on Fehmarn.

The project was developed in the conceptual phase.
