Overview
Femern A/S is a Danish infrastructure-planning company established to prepare and support the delivery of the fixed link across the Fehmarnbelt, the Baltic Sea strait separating the Danish island of Lolland from the German island of Fehmarn. Its central project is an approximately 18-kilometre immersed tunnel designed to carry both rail and road traffic between the two countries. The planned facility is intended to contain a dual-track railway and a four-lane motorway, creating a direct land connection between Scandinavia and northern Germany. The company operates within a bilateral Danish-German framework. Denmark and Germany signed a treaty in 2008 providing the political and legal basis for the fixed-link project. Femern A/S is responsible for planning the tunnel and for preparing the technical, environmental, financial and regulatory basis needed for approvals on behalf of the Danish government. Its role therefore differs from that of a conventional consumer-facing brand or a transport operator: it is principally a public infrastructure project company and delivery organisation. Femern A/S belongs to the Sund & Bælt group. Sund & Bælt Holding A/S is wholly owned by the Danish Ministry of Transport and also has ownership interests connected with other major Danish fixed links, including the Great Belt Fixed Link and the Danish side of the Øresund Fixed Link. Through this structure, Femern A/S forms part of Denmark’s state-backed approach to planning and financing major bridges, tunnels and transport corridors. The company is headquartered in Copenhagen. It has also maintained a representative office in Berlin and public information centres in Burg auf Fehmarn in Germany and Rødbyhavn in Denmark, reflecting the project’s cross-border character and the need for communication with affected communities and stakeholders. A company description cited in the reference material recorded 101 employees as of 1 June 2014. The Fehmarnbelt Tunnel is intended to shorten travel times between northern Germany and Scandinavia and to improve the continuity of road and rail links across the region. The tunnel is being developed together with upgrades to surrounding transport infrastructure. The reference material identifies 2029 as the expected completion year, although the project’s delivery schedule remains dependent on construction, regulatory and other implementation conditions. Femern A/S should therefore be understood as a specialised public-sector infrastructure brand whose identity is closely tied to the planning and realisation of one major cross-border fixed-link project.
History
Femern A/S is the Danish project company associated with the Fehmarnbelt fixed link between Lolland and Fehmarn. Its work is rooted in the treaty signed by Denmark and Germany in 2008, which established the bilateral framework for developing a permanent connection across the Baltic Sea strait. The company was tasked with preparing the project on behalf of the Danish government and with producing the material required for regulatory approval and implementation. The planned solution is an approximately 18-kilometre immersed tunnel rather than a bridge. It is designed to combine a dual-track railway with a four-lane motorway, linking Denmark directly with northern Germany. The tunnel forms part of a broader programme that includes improvements to related road and rail infrastructure. Its strategic purpose is to reduce journey times and strengthen transport connections between Scandinavia and continental Europe. Femern A/S operates as a subsidiary of Sund & Bælt Holding A/S. Sund & Bælt is wholly owned by the Danish Ministry of Transport and is also associated with the companies responsible for the Great Belt Fixed Link and the Danish side of the Øresund Fixed Link. This ownership model places Femern A/S within Denmark’s state-controlled infrastructure group rather than in the private commercial transport sector. The company is based in Copenhagen and has maintained a representative office in Berlin, together with public information centres in Burg auf Fehmarn and Rødbyhavn. These locations reflect the project’s Danish-German scope and the importance of public engagement around a large construction project. The cited company information reported 101 employees on 1 June 2014. The reference material states that the tunnel was expected to be completed in 2029. Femern A/S’s continuing role is to support the planning, approvals and delivery preparation for the fixed link and its associated infrastructure.
