Underwater Tunnel Will Connect Denmark and Germany in Just 7 Minutes. Meet the Fehmarnbelt Tunnel, the Largest Underwater Tunnel in the World, Promising to Be Ready by 2029.
Tunnel Will Connect Denmark and Germany: Quick trip connecting countries in just minutes: Meet the Fehmarnbelt Tunnel, the LARGEST underwater tunnel in the WORLD. Have you ever imagined crossing borders in less than 7 minutes? This is the incredible proposal of the Fehmarnbelt Tunnel, the largest underwater tunnel in the world. With an extension of 18 kilometers, it connects Rodbyhavn in Denmark to Fehmarn in Germany. Currently, the route between these two points is only possible by ferry, a journey that takes 45 minutes. With the new tunnel, this time will be drastically reduced, transforming the way we travel between the two countries.
The expectation is that the Fehmarnbelt Tunnel will revolutionize transportation in the region, offering a fast and efficient alternative that promises not only to ease the lives of travelers but also to boost trade and tourism between Denmark and Germany. Stay updated on this news that will change the way we see international travel!
The Largest Underwater Tunnel in the World Will Be Ready in 2029 and Will Be a Significant Milestone for the Construction Industry!
The journey through the tunnel connecting Denmark and Germany can be made by train, lasting seven minutes, or by car, lasting ten minutes.

Florianópolis will receive a million-dollar BRT that will begin construction in 2026 with nearly 400 million in funding from the federal government and the Inter-American Development Bank, and the map already shows the routes for the exclusive bus corridors.

Without a blueprint, without an engineer, and using scrap from the dump, a father spends 15 years building an 18-room castle for his daughter, featuring tram tracks, 13 fireplaces, and over 700 m², which may now be demolished.
The route traced across the Baltic Sea will also be the shortest between the Scandinavian region and the rest of Europe. Construction of the Fehmarnbelt Tunnel began in 2020 on the Danish side and in 2021 on the German side. The expectation is that the largest underwater tunnel will be ready by 2029.

Imposing, the construction of the tunnel will connect Denmark and Germany and requires 360,000 tons of steel, equivalent to what is needed to build 50 Eiffel Towers like the most famous postcard in Paris. About 19 million cubic meters of sand, stone, and soil are being dredged to accommodate the Fehmarnbelt Tunnel.
At sea, hundreds of sailors are working to submerge the built parts of the largest underwater tunnel in the world, divided into 70 standard sections and 10 special ones. Each of them weighs 73,000 tons and is 217 meters long.
The Expectation is That the Fehmarnbelt Underwater Tunnel Can Operate for at Least 120 Years
The pieces are assembled and fused on land, to then be positioned on the seabed with the help of boats. The tunnel will connect Denmark and Germany, and according to the project’s website, around 60 to 70 vessels have been employed for this purpose.

When the largest underwater tunnel in the world is complete, teams of technical and mechanical installations will work simultaneously to equip the largest underwater tunnel in the world with rail tracks, ventilation, cameras, signage, paintings, among others. There is also a portal that connects the Fehmarnbelt Tunnel to the submerged part with the railway and the road on land.
The expectation is that the largest underwater tunnel will operate for at least 120 years. Besides reducing travel time between European countries, the project aims to reduce CO2 emissions by offering a shorter and faster route, as well as reducing congestion on the roads.
Tunnel Will Connect Denmark and Germany After Billion-Dollar Investment
The Fermarn A/S, the company responsible for execution, highlights that the Fehmarnbelt Tunnel is one of the largest infrastructure projects in Europe, with a total budget of over US$ 7.1 billion. The project began in 2008 when both countries signed a treaty for its construction, facing legal and environmental challenges that delayed its implementation for over a decade.
Another important point is that its construction involves a large amount of materials, so much so that the construction site on the Danish side occupies a vast area comparable to 373 football fields. The tunnel consists of 79 standard sections and 10 special sections, each weighing about 73,000 tons and measuring 217 meters long by 42 meters wide and 10 meters high.
These sections are being manufactured on land, transported by ferry to the installation site, and then submerged and sealed at a depth of 40 meters.
