In order to providing the new coastline once the sea covers the front of the tunnel portal, a new dyke with 200m length and 4.5m-hight has been completed over the Fehmarnbelt Tunnel portal.
While the construction consortium Femern Link Contractors (FLC), comprising Vinci, Per Aarsleff, Wayss & Freytag, Max Bogl, CFE, Soletanche Bachy and BAM, has worked on the portal, an outer temporary dyke has kept the water out.
Bulkheads have been placed on the end of the tunnel facing the water and these can be removed from the inside after the first tunnel element is immersed and connected later this year.
For completing the 260m-long tunnel portal, behind the dyke work is continuing.
Linking Rødbyhavn on Lolland in Denmark and Puttgarden on the German island of Femern, the immersed tunnel beneath the Baltic Sea is 18km long and will consist of 79 217m-long hollow, reinforced concrete elements and 10 special elements.
