Fehrmarnbelt Link’s tunnel design (stretching for 18 km) aimed to link Lolland Falster in Denmark to Schleswig Holstein in Germany gets a go-ahead.
The proposed immersed tunnel is arguably one of Europe’s mega-projects, designed to focus on public transport’s improvement, supporting the tourism industry and economic growth simultaneously.
The project is being delivered for Femern A/S by a consortium of VINCI Construction Grands Projets (leading contractor for the two tunnels), Per Aarsleff (leading contractor for the portal), Royal BAM Group, Solétanche-Bachy International, CFE, Dredging International, and Max Bögl Stiftung & Co.
Femern A/S invested €7 billion to build a road and rail tunnel made up of hollow concrete elements, cast on land, and assembled section by section to form the tunnel.
An 8 kilometers long trench (60 m wide x 16 m deep) in the seabed must be placed. Thereafter tunnel elements made of concrete, each weighing 73,000 tonnes, will be “towed by large tugboats before being lowered down.”
