Construction site at Røbyhavn

Northern Europe’s largest construction site

The majority of activities concerned with the building of the Fehmarnbelt tunnel takes place at the main construction site at Rødbyhavn on Lolland.

This is where the large factory is located, where the 89 tunnel elements are produced. The factory and the Danish work harbour together cover an area of around 1.5 million m2, which is equivalent to 310 football pitches.

The finished tunnel elements will later be towed to the Fehmarnbelt via the Danish work harbour and immersed into the Baltic Sea.

Slightly west of the factory, the Danish tunnel portal is being constructed, which provides the transition from the motorway and railway on land to the tunnel tube.

The tunnel town

Several thousand workers are needed to construct the Fehmarnbelt tunnel. When the work reaches its peak, around 1,300 tunnel workers will live and work at the site. For this purpose, a special tunnel town has been built between the tunnel portal and the production plant.  

The town is divided into nine districts. Every tunnel worker has their own single room with their own bathroom and WC. There are also communal facilities, such as a clinic, a supermarket, games room, gym, etc. The tunnel town is linked together by new cycle paths, which make it easy for workers to get around the construction site and the neighbourhood.

The tunnel village consists of numerous containers stacked on top of each other, which form the individual rooms. They are arranged in square blocks, creating an inner courtyard in the middle of each block. The surrounding area is green.

Special dredging vessels have dredged the 18 km tunnel trench. The tunnel elements will be immersed into the tunnel trench and joined together.
