The 18 km Fehmarnbelt fixed link will be the world's longest road and rail tunnel, connecting Denmark and Germany. The immersed tunnel will comprise a four-lane motorway and two electrified rail tracks, and consist of 79 individual elements, each 217 metres long.
Once complete, the journey through the tunnel will take just ten minutes by car and seven minutes by train, saving about one hour of travel each way.
As one of hundreds of projects within the trans-European transport network (TEN-T), this "green corridor" will help improve mobility, cohesion and interoperability within the European Union and result in an overall reduction in CO2 emissions.
COWI is acting as primary consultant for the Femern Link Contractors on this major infrastructure project.
