The Fehmarnsund tunnel is to connect the island of Fehmarn with the Schleswig-Holstein mainland and as an immersed tunnel to cross under the Fehmarnsund . In four tubes, the tunnel will accommodate federal highway 207 with four lanes and the Lübeck – Puttgarden railway line with two main tracks. Commissioning is to take place at the same time as the Fehmarnbelt tunnel in 2028 .

Starting position

The state treaty of 2008 between Germany and Denmark provides that the hinterland connection to the Fehmarnbelt link is to be expanded on the German side . The Fehmarnsund Crossing should be excluded from this: On the Fehmarnsund Bridge, the road connection should remain two-lane and the railway line should remain single-track.

Regardless of this, the Schleswig-Holstein state government announced the construction or expansion of a Fehmarnsund crossing for the Federal Transport Infrastructure Plan 2030 , because it considered the Fehmarnsund Bridge to be a bottleneck in the German hinterland connection.

Decision-making for a new link

The need for upgrading was proven by a stress test on the Fehmarnsund Bridge in 2010 and by an expert report by Deutsche Bahn from December 2012. Accordingly, the construction of the existing Fehmarnsund Bridge is not able to withstand the higher loads after the opening of the Fehmarnbelt Fixed Link.

In coordination between the Federal Ministry of Transport , the Ministry of Economics, Transport, Labor, Technology and Tourism of the State of Schleswig-Holstein and DB Netz , four variants were subjected to preliminary planning:

New construction of a combined bridge for rail and road
Construction of two separate bridges
Construction of a combined immersed tunnel
Construction of a new bored tunnel with at least four tubes

A double-track railway line and a four-lane road connection were planned in each case; the maintenance of the existing Fehmarnsund Bridge for local road, bicycle and pedestrian traffic was also examined.

Variant decision

On November 13, 2019, Deutsche Bahn presented four preferred options for the planned new Fehmarnsund crossing to the public in a special meeting of the “ Dialog Forum Fixed Fehmarn Belt Link”. Subsequently, the “Dialog Forum Fixed Fehmarn Belt Link” and a “Round Table Fehmarn Sound Link” set up by it dealt intensively with the effects of the various options. As a result of the discussion, the construction of an immersed tunnel while retaining the Fehmarnsund Bridge was approved. In a joint press conference on March 3, 2020, the Parliamentary State Secretary to the Federal Minister for Transport and Digital Infrastructure, Enak Ferlemann , DB Infrastructure Board Member Ronald Pofalla and Schleswig-Holstein Transport Minister Bernd Buchholz announced that

the Federal Ministry of Transport, the State of Schleswig-Holstein and Deutsche Bahn compared all the variants and opted for an immersed tunnel for road and rail
the Fehmarnsund Bridge is to be preserved.
