Fehmarnbelt Fixed Link

  • An immersed tube tunnel with associated landside works between Denmark and Germany.
  • Includes four-lane motorway and a two-track, electrified railway.

The Fehmarnbelt Fixed Link consists of an immersed tube tunnel project with associated landside works between Lolland in Denmark and Fehmarn in Germany.

The tunnel is of a unique scale and will set a new record in terms of length and depth. The length will be 18km with foundation depths reaching more than 40m under the sea surface.

The tunnel will carry a four lane motorway and a two track railway.

Arup, in joint venture with Ramboll and TEC, are responsible for the design and development of the immersed tunnel for Femern A/S.
The JV’s scope includes multidisciplinary design from preliminary design through to preparation of tender documentation, including conceptual design, plan approval, illustrative design and D&B Tender Documentation.

Arup provided international experience to Fehmarnbelt and delivered an innovative approach to the tunnels longitudinal ventilation.
