The teams are still waiting on a German construction permit, which depends on environmental approval.

The four contracts are: Tunnel North Contract; Tunnel South Contract; Tunnel Portals and Ramps Contract; Tunnel Dredging and Reclamation. The first three were signed with the Femern Link Contractors JV (FLC) and the last was signed with Fehmarn Belt Contractors (FBC).

FLC consists of Vinci Construction Grands Projects, Per Aarsleff Holding, Wayss and Freytag, Max Bogl, Bachy Soletanche, CFE, Bam Infra, Bam International, and Dredging International.

FBC consists of Boskalis International, Van Oord Dredging and Marine Contractors, Hochtief, and Zublin.

The Fehmarnbelt project aims to construct an 18km-long immersed tunnel between Denmark and Germany. Past estimates have put the project at USD 7.3bn.
