Fehmarnbelt fixed link, Lolland (Denmark) and Fehmarn (Germany)

Four lane motorway and a double track railway line between Denmark and Germany

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.
