Preparations for the upcoming four-lane road connection to the Fehmarn Belt Link are now visible in the northern German landscape.

The construction of the tunnel portal on Fehmarn has been visible for several years, and now forest clearing has begun in preparation for the future four-lane road connection to the fixed link between Denmark and Germany.

As we move into 2025, the German project organization DEGES – Deutsche Einheit Fernstraßenplanungs- und -bau GmbH – is taking stock of the German construction work related to the Fehmarn Belt Link.

DEGES is managing the construction work on the German mainland and on Fehmarn Island in three projects:

  • Construction of the road section from Heiligenhafen to Fehmarnsund
  • Building of a Fehmarnsund tunnel, and
  • The connection at Puttgarden to the Fehmarn Tunnel

Expansion of B207 to a four-lane motorway

The work to expand the 16.3 km long section of the B 207 on the German mainland, from Heiligenhafen Ost to Fehmarnsund, is now underway with forest clearing and cable laying.

The section will be expanded into a four-lane motorway with a hard shoulder, and the work is expected to be completed by 2027/2028, according to DEGES, which states that the expansion will improve traffic safety and increase capacity. The overall goal is to reduce traffic jams, particularly during summer holidays and travel season.

Construction of a Fehmarnsund Tunnel

The current road and rail connection between the German mainland and Fehmarn Island crosses the 963-meter-long Fehmarnsund Bridge, which was opened in 1963.

Studies have shown that the bridge will not be able to withstand future traffic loads, and threfor it has been decided on the German side to construct a 1.7 km long submerged tunnel with four lanes for road traffic and two tracks for trains.

Construction work has not yet started, but the tunnel is expected to be completed and ready for use by 2029, alongside the completion of the Fehmarn Tunnel.

The listed Fehmarnsund Bridge – also known as the “Hanging Bridge” – will be renovated so that it can continue to be used by pedestrians, cyclists, and slow traffic in the future.

Connection to the Fehmarn Tunnel

Denmark is responsible for the planning, construction, financing, and operation of the fixed Fehmarn Belt connection, as well as the expansion of the Danish approach.

The German project organization DEGES is supporting the construction of the two tunnel tubes for road traffic on the German side, where work on the construction of the tunnel portal in Puttgarden began in 2021.

The work on the connection to the Fehmarn Tunnel in Puttgarden is expected to be completed in parallel with the commissioning of the Fehmarn Tunnel in 2029, according to DEGES.

Significant increase in German tourists due to the Fehmarn Tunnel project

feriehus-femern-belt-development

According to an analysis conducted by the tourism alliance SMA-Z, 10 million Germans have Zealand, Lolland-Falster, and Møn on their radar for a holiday within the next three years. The study also shows that German tourists’ interest in visiting eastern Denmark will increase significantly once the Fehmarn Belt Tunnel opens, writes Business Lolland-Falster in a press release.

For 52% of travel-inclined Germans, the tunnel raises the likelihood of visiting eastern Denmark. This means that more than 5 million Germans are more likely to travel to Zealand, Lolland-Falster and Møn when the Fehmarn Belt Tunnel opens in 2029.

500,000 More Overnight Stays 
The shorter travel time and easy access make a vacation in Lolland-Falster even more attractive for Germans. At the same time calculations indicate that the number of international overnight stays in the Zealand region will increase by more than 500,000 solely due to increased accessibility once the Fehmarn Belt Tunnel opens in 2029.
These calculations, conducted by HBS Economics, do not account for tourism-promoting activities that will build on this ease-of-access to Denmark.

German Tourism Potential Needs to be Considered 
Lindy Kjøller, Destination Manager at Visit Lolland-Falster and Project Manager for SMA-Z, welcomes the analysis and points out that the Fehmarn Belt Tunnel will transform the entire tourism sector's self-perception on the eastern side of the Storebælt.
“For many years, we have primarily focused on Danish visitors in Zealand, Lolland-Falster, and Møn because they are the majority. But in a few years, this could turn completely around, with German tourists filling vacation homes and hotel beds. This places new demands on our reception facilities,” says Lindy Kjøller.

This means that tourism businesses need to consider German-speaking staff, signage, and websites in German. In fact, 46% of German tourists that participatet in the survey state that it is important for them that staff understand and speak German, and 55% prefer brochures, maps and guides in their native language. Both studies are the first to clarify the tourism potential related to the Fehmarn Belt Tunnel.

Good News for Tourism 
The possibility that increased German interest in eastern Denmark may already materialize in the coming three years, with 10 million German tourists potentially finding their way to Zealand, Lolland-Falster, and Møn, is good news for tourism, but it poses two very specific challenges.
“Accommodation capacity and qualified workforce are the main barriers to growth. The Fehmarn Belt Tunnel could help solve our labour challenges by enabling us to attract employees from a much larger area. However, the tunnel also opens up completely new customer groups from northern German cities who prefer to stay in hotels, and we have too few of those,” says Lindy Kjøller.

43% of respondents from Berlin indicate that it is likely they will travel to Zealand and Lolland-Falster. Although city dwellers often prefer to stay in hotel rooms, most German overnight stays take place in Danish holiday homes, and there is also a shortage of those.

Facts About Strategic Marketing Alliance – Zealand 
The Strategic Marketing Alliance – Zealand (SMA-Z) is a new, unique alliance that aims to strengthen tourism in Zealand, Lolland-Falster, and Møn and foster strategic collaboration in analysis, marketing, and development among the five destinations outside Copenhagen: Visit Sydsjælland og Møn, VisitFjordlandet, VisitNordsjælland, Destination Sjælland, and Visit Lolland-Falster. Additionally, VisitDenmark, Danish Coastal and Nature Tourism, Erhvervshus Sjælland, and Erhvervshus Hovedstaden are part of the project.

The vision is for Zealand, Lolland-Falster and Møn is to stand as strong as possible as a tourism area when the permanent Fehmarn Belt Tunnel opens in 2029. This will be achieved through a coordinated marketing effort and core narrative.
The project aims to increase the number of international tourists, especially Germans, and to create a more sustainable tourism sector in Zealand, Lolland-Falster and Møn by better utilizing capacity throughout more of the year and enhancing the environmental sustainability and appeal of tourism products, particularly for environmentally conscious German travelers.

Important Milestone in the Construction of the Fehmarn Connection: The First of a Total of 89 Tunnel Elements has been Cast

From Preparation to Execution – A Complicated Process

Patience is a virtue – especially when complicated designs, calculations, and processes must be transformed into reality.

Every beginning is hard, and the casting of the first element has indeed taken about 10 months, whereas it is expected that the elements can be produced in 9 weeks going forward.

“It has been a long and complicated task to cast such a large concrete structure, and it has now been demonstrated that technology and methods work well together,” says Henrik Vincentsen, CEO of Femern A/S in a press release.

Going forward, the elements can be cast at a completely different pace, precisely because meticulous data and know-how have been gathered in the process around the casting of the first element, and because all 5 production lines are now operational. Similarly, the casting process will be optimized as the workers accumulate more and more knowledge and experience.

A Great Achievement

There is also pride to be found at the executing consortium Femern Link Contractors (FLC) over the achieved milestone. “Casting a single tunnel element is a great achievement in itself, but we still have a long way to go. Nowhere else in the world are concrete elements of this size mass-produced, but that is exactly what we must master in the coming years. Our goal is to turn the exceptional into routine,” says FLC Director Sébastien Bliaut.

The fact that this is a GREAT achievement is emphasized by the size of each element. An element is 217 meters long, composed of 9 segments of 24 meters each. An element weighs 73,500 tons.

The Further Process

The finished element must now cure for 3-4 weeks before steel bulkheads and the ballast tanks that will ensure the element’s stability during submersion are mounted. Meanwhile, the production of the remaining 78 elements continues on 5 production lines, while a separate line produces an additional 10 special elements. According to the plan, the first tunnel element, to be mounted at the tunnel portal entrance, will be submerged later in the year.

The Fehmarn Belt Fixed Link is at the centre of a new development strategy for Region Zealand

"The Fehmarn Belt Fixed Link allows us to have great visions. It is a unique opportunity to make us into a European hub for green growth, innovation, exchange and international co-operation. It is therefore crucial that we already now plan for the long term, so that we can realise the many potentials the connection creates for the entire Region Zealand," says Heino Knudsen, commenting on the new development strategy for Region Zealand, which was recently adopted by a unanimous regional council.

The strategy is divided into five key themes that set an ambitious and sustainable direction for the region for the next 10 years and paves the way for partnerships and initiatives that will make the region more green, attractive and internationally orientated.

Development in a sustainable direction
In addition to the Fehmarn Belt Link, another recurring focus in the new strategy is sustainable development - this applies not only to the environment and climate, but also that the social and economic development of Region Zealand moves in a sustainable direction. It emphasises the importance of strategic partnerships, fundraising, international collaboration and the involvement of citizens and partners in the development process.
"The development strategy is an invitation for co-operation across borders, sectors and walks of life. It is a strategy for the entire geography of Region Zealand, where we must work together on pulling in the same direction, so that Region Zealand remains an attractive, dynamic and sustainable region for both present and future generations," says Christian Wedell-Neergaard, Chairman of the Regional Development Committee, Education, Public Transport and International Cooperation.

Construction of a unique viewpoint for the Fehmarn belt construction started

pilen-femern-belt-development

The establishment of a new viewpoint - Pilen (The Arrow) - over the construction of the Fehmarn Belt tunnel was launched on 11th January 24, with the groundbreaking ceremony by Mayor Holger Schou Rasmussen, Lolland Municipality and CEO Mikkel Hemmingsen, Sund & Bælt, Femern A/S announces.

Unique front row view
The Arrow will be located on reclaimed land a few hundred metres from where the first tunnel element will be sunk into place and where traffic will enter the tunnel in the future. This will give visitors to the area a unique front row view of the extensive tunnel construction.

An experience in itself
The Arrow will be a ramp that gradually rises 217 metre upwards, which is the same length as a tunnel element, ending in a head pointing towards Germany.

The highest point of the ramp will be 24 metres above the surrounding landscape.

From The Arrow, visitors will be able to follow the floating departure of the tunnel elements, as well as following the construction of the tunnel portal and the future road and railway connection into the countryside.

The project also includes a new ramp and access path from the nearby car park on Gl. Badevej in Rødbyhavn.

In addition to giving visitors a better view of the work on the 18-kilometre-long immersed tunnel, a visit to The Arrow will be an experience in itself.

Aarsleff A/S is the entrepreneur working on the establishment of The Arrow, that is expected to be open to visitors at the beginning of 2025.
