Fehmarn Belt Connection

The Fehmarn Belt Connection will stretch approx. 20 km in length and thereby be the world’s longest immersed tunnel, linking Denmark and Germany with a four-lane motorway and a double-track railway. As an international infrastructure project, the connection places particular demands on landscape-strategic holistic thinking and design, supporting technical, aesthetic, and societal values.

On the Danish shore, Schønherr has designed the architectural layout of the toll station, customs facilities, and border control at Rødbyhavn. The facility is integrated into the landscape with a focus on function, scale, and aesthetics, contributing to a harmonious transition between infrastructure and the coastal zone.

The large quantities of seabed material from the tunnel excavation are actively used for coastal landscape formation. In front of the existing dike, a new wetland is created with shallow lakes, salt meadows, and wetland habitats. These provide important habitats and resting areas along the European bird migration route – nown as the “Bird Flight Line” – and restore a coastal landscape closer to Denmark’s historic landscape form.

The project also includes green corridors, ecological linkages, and recreational paths that support both biodiversity and human access. In this way, infrastructure is combined with nature and experience, creating added value for the local community through a long-term, sustainable landscape strategy.
