Fehmarn Belt Tunnel to be Built

German Federal Court rules in favor of multi-billion Euro project; Construction may begin.

LEIPZIG/ FEHMARN/ FLENSBURG- It’s supposed to be the longest tunnel in Europe, at 18 kilometers (11.3 miles), carrying train and vehicular traffic. Instead of bottlenecks going through Fehmarn Island and a 45-minute ferry ride between Puttgarden and Rodby, the trip would be 10 minutes. The time from Hamburg to Copenhagen reduced from five hours to only three.  Yet the project has been an eyesore and a platform for hefty debates for over a decade between those favoring the project and those opposing it. Their arguments: noise pollution due to a high increase in traffic, irreversal damage to the reefs in the Belt region between the Danish island of Lolland and Fehmarn, and the endangerment of porpoise, and financial ruin due to construction.

Now the German Federal Court has decided: The Tunnel can be built.  The ruling happened in Leipzig today, putting the decade long battle to a permanent end. The argument was that the contract between Denmark and Germany was signed in 2008 and ratified a year later. Denmark has already received the green light to build the tunnel since 2015 and will bear the majority of the cost- namely, 7.1 billion Euros- for building the mammouth structure that will run below the sea floor and will feature two parallel tunnels- one for vehicular traffic and one fort rain traffic. Germany will cover 3.1 billion in costs for rail tracks and for widening the highway. According to the court, the contract cannot be rescinded.

With the green light to replace the Fehmarn Bridge on the south end of the island, the plan to complete the entire stretch of the Motorway 1 from Hamburg to Copenhagen will be realized. Currently, only a 15 kilometer stretch of non-freeway route exists between Oldenburg on the main land and Puttgarden on the island, minus the ferry route, all of it is two-lanes with only one exit and one half-exit going to Burg, the largest community on Fehmarn Island.

Once a one-track route, the construction of the tunnel on both ends of Fehmarn Island will allow for the expansion of the rail line between Lübeck and Fehmarn to allow for two tracks to run along the Baltic Sea coast. Currently, only the line between Lübeck and Hamburg as well as from Ringsted to Copenhagen are electrified; the rest of the route- Ringsted to Rodby and Lübeck to Fehmarn require diesel locomotives to operate. Since December 2019, no train ferries between Puttgarden and Rodby have operated resulting in long-distance trains to detour via Neumünster, Flensburg, Pattburg and Kolding (Denmark), while regional trains end in Burg on Fehmarn Island. It is hoped that regional trains will use the new route and the route to Fehmarn will remain in use.

Strutkamp, located next to the Migratory Route and 1 km north of Fehmarn Bridge. This village would be a memory if a new bridge is built to replace the 1963 span.

The entire project, with tunnels connecting Fehmarn with Denmark and the German mainland, a motorway with four lanes and rail lines to accommodate regional and long-distance train services is expected to be completed by 2029. Already Denmark has marched ahead with its end of the tunnel. With Leipzig’s ruling, construction will begin on the German side for the Belt Tunnel project. It is hoped that noise barriers and mitigation of flora and fauna will be considered during this venture, considered the most expensive in Europe as of yet.

If there is one consolation, the Fehmarn Bridge, connecting the island with the German mainland, will remain as is, once the German tunnel is completed. Built in 1963, the world’s first basket weave tied arch bridge was rehabilitated in 2019 with the plan of leaving it open for local traffic, including cyclists and pedestrians. It’s considered not only the icon for Fehmarn and for the state of Schleswig-Holstein, but also for bridge engineering, as it’s being used as a model for other bridges of its kind that are either being built or will be built in the near future. This includes the Levansau Bridge near Kiel, spanning the Baltic-North Sea Canal. The replacement is scheduled to be built come 2021.

The Fight to Save Fehmarn Island from Progress

FEHMARN, GERMANY-   Last fall, the Bridgehunter’s Chronicles did a segment on the preservation of the Fehmarn Bridge, the first bridge in the world that carries the now popular basket-handle tied arch bridge span. The battle is part of the series where residents of Fehmarn Island are fighting with both the German and Danish governments to stop a project where the Migratory Bird Route, connecting Hamburg and Copenhagen, would be widened- both the highway and the railway. This includes new bridges to replace the Fehmarn Bridge and a tunnel on the opposite end connecting Puttgarden (D) and Rodby (DK). And lastly an industrial areal was planned for the island.  Unfortunately, despite the Areal being blocked earlier this year, the European Union, according to reports from the BBC, has given Denmark the green light to start the construction of the tunnel, by providing 589 million Euros in the next four years for the project.

Yet while the Danes are prepared to start work beginning this fall, residents of the island and the surrounding area along the Baltic Sea coast are up in arms against the project and have started their own initiative to stop the project.


Tourists and locals have seen the blue X’es popping up in neighborhoods, along highways and beaches and even in the skies between Hamburg and Lübeck and the island itself. The Blue-X Initiative was adopted by the groups Preserve Fehmarn and Beltretter, with the purpose of showing support for preserving the island and stopping the project from taking place. Almost one in every three households have this on their lawns as a way of demonstrating solidarity against the project. And there are many reasons for this initiative:

1. The construction of the tunnel would coincide with the expansion of the highway and rail line going through the island as well as the construction of the new Fehmarn Bridge, resulting in the island becoming a construction site. As small as the island is, and with the economy being dependent almost solely on tourism, analysts predict a loss of up to 800 million Euros (or close to $1 billion) in revenue during the time of the construction because of loss of tourism and commerce, plus additional money to improve the island’s imagery once the project was completed, which could take years to complete.

2. The project would involve a loss of sensitive vegetation and marine life that would be immense and possible irreplaceable. This includes the plan to scrap the underground tunnel similar to the Euro-Tunnel connecting France and Great Britain in favor of one above the sea floor, similar to the Oresund Bridge and Tunnel between Copenhagen and Malmö (Sweden), which could be devastating to marine life alone. The width of the construction area between Puttgarden and Fehmarn Bridge would average approximately five kilometers. The maximum width of the island is only 21.8 kilometers- and this given the size of the land to be 185 squared kilometers!

3. Some discreptancies in the environmental and economic impact surveys conducted by Denmark have resulted in rechecking the figures. Alone with the economic impact survey released in January 2015 led to a debate on the credibility of both the Danish government, the conglomerate spearheading the tunnel initiative Fehmarn A/S, and even the European Union. While both Denmark and the EU claim that the new crossings would produce a revenue of 4-5% of the gross domestic product in the region or approximately 3.48 billion Euros ($5.5 billion), other surveys indicate that the loss of revenue through construction combined with years of recovery, the new crossing would net an annual loss of 6.7 billion Euros ($8.2 billion). For the residents on the island, the risk would be too high to take.

4. While there is a one-track rail line that is suitable for transport between Hamburg and Copenhagen including the time needed to cross via ferry, there is another border crossing at Flensburg and Padborg, where they feature a freeway and a two-track rail line connecting Hamburg with Aarhus with a arm going to Copenhagen via Odense. At the present time, improvements are being made in the Flensburg area to make the crossing more attractive. While the logic behind expanding the line through Fehmarn is there, little do government authorities realize that Fehmarn is a vacation and natural area whose need for a freeway/ two-track crossing on both ends of the island would devastate the natural habitat and impact tourism negatively. In other words, better to go through Flensburg if you wish to stay on the freeway going to Denmark and not stop to go swimming.


While officials in Denmark are preparing to start building the tunnel from the Rodby end, officials in Germany are in the process of discussing the project with many parties involved. This after the application for the construction of the new Fehmarn Bridge, new freeway and tunnel was submitted to the state ministry of transport. The communities affected will have a meeting in September, followed by the environmental groups, including BeltRetter in November and residents affected by the construction afterwards. The ministry will then review the opinions and information provided by those affected before making their decision- a process that could take up to a year.  Proponents of the project have already received a backing from The German Railways (The Bahn) and German Minister of Transport Alexander Dobrindt, the former wanting to expand and electrify its rail line to run more ICE-Trains on there.

But with the opposition towards the project crystalizing and spreading beyond the region, problems will most likely excaberbate over the course of two years, especially when the blue X’es sprout up everywhere making the area as blue as possible. Since blue is the sign of clear water, the water people deserve to swim in and marine life to inhabit, it also is a sign of preserving things as they are. With more initiatives coming up and more support pouring in, there is a chance that the project could be stalled further or even scrapped. If this is the case, then there will still be some work to be done with its current infrastructure to keep it up to date, but residents will breathe a sign of relief, for having a mega-highway for the sake of expanding commerce is not necessarily what they want. In fact with all of information on the negative impacts, combined with questions involving the credibility of the sources, this project in the end will do more harm to the region than good. This is something no one is willing to gamble on.

The Flensburg Files and the Bridgehunter’s Chronicles are proud to support the initiative to preserve Fehmarn Island and its places of interest. Both columns will provide you with further updates on the latest involving the project.
