After completion, the tunnel will not be an obstacle to vessel traffic in the Fehmarnbelt. Also during the construction phase, safety at sea has the highest priority.

The Fehmarnbelt tunnel will be just as safe to use as equivalent routes on land. It includes an emergency lane and emergency exits along the entire length.

The tunnel is monitored round-the-clock both from the tunnel’s own local control centre, LCC, on the Danish side of the Fehmarnbelt, and from the rail traffic control centre in Copenhagen, TCC.
