Fehmarnbelt Days 2025: A symbol of cooperation and freedom!
On June 17, 2025, the “Fehmarnbelt Days 2025” event took place in the Lübeck Music and Congress Hall and was met with great interest. Over 25,000 visitors flocked to the community festival, while more than 500 participants took part in the specialist conference. The focus is on the mega-project of the Fehmarnbelt Tunnel, which was considered one of the central topics. The Chamber of Commerce and Industry (IHK) organized the event, which addressed citizens from the Hanseatic League, northern Germany and neighboring Scandinavian countries. As hl-live.de reports, the event represented a call for cross-border cooperation, especially to strengthen democratic values and resilience against autocratic tendencies.
The specialist conference covered interesting topics such as security, freedom and coexistence in Europe. Particularly noteworthy was the panel discussion, in which, among others, Schleswig-Holstein's Agriculture and European Minister Werner Schwarz as well as Swedish Ambassador Veronika Wand-Danielsson and Environment Minister Tobias Goldschmidt had their say. Their message: solidarity against autocracies is important.
The Fehmarnbelt Tunnel – A mammoth project
One of the largest construction projects in Northern Europe, the Fehmarnbelt Tunnel, has been in the headlines since work began in 2021. This 18 kilometer long underwater tunnel will connect the German islands of Fehmarn and Lolland in Denmark. Scheduled for completion in 2029, the tunnel will be the longest of its kind in the world. Drivers and train passengers should get from one side to the other in just 10 minutes, as meteoweb.eu emphasizes.
The construction work is under the supervision of Femern, a subsidiary of Sund & Bælt. With a budget of 7.1 billion euros, not only a four-lane highway will be built, but also an electrified high-speed railway. This will reach speeds of up to 200 km/h and significantly shorten the journey between Hamburg and Copenhagen - to just 2.5 hours. The connection will also promote lower-emission mobility by reducing the need for flights and significantly reducing the time spent on road journeys.
Ecological aspects of the project
The sustainability requirements for the tunnel are high. According to Wikipedia, the concrete is produced with low carbon emissions and uses environmentally friendly technologies and recycling of waste materials. The tunnel's underwater route also minimizes the risk of shipping accidents and ensures that fewer are affected by the often challenging weather conditions typical of bridges.
The construction work currently has to overcome some challenges. Even though the project has weathered the COVID-19 pandemic well, material availability and weather-related delays are commonplace. Nevertheless, Henrik Vincentsen, CEO of Femern, is optimistic about the planned completion by 2029.
Those interested could also find out more about the tunnel at information stands during the Fehmarnbelt Days, and the feedback from partners was consistently positive. The next edition of Fehmarnbelt Days will take place in Helsingborg, Sweden in 2027, and the anticipation for the giant under the sea is already palpable.
