The Fehmarn Belt Fixed Link was tentatively expected to be completed in the year 2018, but the date has been changed to 2020. Originally conceived as a bridge, in December 2010 Femern A/S announced that a tunnel was preferable to a bridge as this would present fewer construction risks, although the financial cost would be broadly similar.

Project

Beginning at least as early as 2000, German and Danish transportation planners pushed for a "fixed link" – either a bridge or a tunnel – across the Fehmarn Strait. A bridge was widely regarded, for years, as the most likely scheme, and it was somewhat surprising when the Danish project planners selected an immersed tunnel design in late 2010.

This project is comparable in size to that of the Øresund Bridge or the Great Belt Bridge.

On the German side, the road will be upgraded to four lanes and the railway to double track and, according to the treaty, paid by the German tax payers rather than by user tolls.

 design submitted by the Ramboll, Arup and TEC consortium. According to the senior project managers, as well as being the world's longest immersed tunnel, it will be the world's longest combined road and rail tunnel; the world's longest under water tunnel for road; the deepest immersed tunnel with road and rail traffic; and the second deepest concrete immersed tunnel. The size of the project is about five times the tunnel part of the Øresund Link between Denmark and Sweden, currently the longest immersed concrete tunnel.

The deepest section of the Fehmarn Belt Trench is 35 metres and the tunnel sections will be about 10 metres high, thus the dredging barges will need to be capable of reaching depths of over 45 metres. Dredging will produce a trench some 40–50 meters wide and 12–15 metres deep. These parameters give a total of some 20 million cubic metres (m3) of soils to be dredged. Conventional dredging equipment can only reach to a depth of about 25 metres. To excavate the middle portion of the Fehmarn trench – deeper than 25m below the water's surface – will likely require grab dredgers and trailing suction hopper dredgers.

The proposed tunnel would be 17.6 km long, 40m deep (below the surface of the sea), and would carry a double-track railway. Arguments brought forward in favour of a tunnel include its starkly reduced environmental impact, its independence from weather conditions, as crosswinds can have considerable impact on trucks and trailers, especially on a north–south bridge.

 tunnel sections will have a rectangular cross-section that is about 40 metres wide and 10 metres high, containing four separate passageways (two for cars and two for trains), plus a small service passageway: There will be separate Northbound and Southbound tubes for vehicles, each 11 meters wide, each with two travel lanes and a breakdown lane; while the Northbound and Southbound passageways for trains will be 6 metres wide (each) and about 10 meters high; the service passageway will be 3 meters wide; the standoff space between each "tube" will vary, but the overall width will be 41.2 metres. The single-level, sectional arrangement of the two road and rail tubes side-by- side – with the road West and the railway East – coincide with the arrangement of the existing road and rail infrastructure and requires no weaving to connect.

Bridge characteristics

Initially, a bridge was proposed. The bridge would be about 20 km long, comprising three identical cable-stayed spans

. On 26 March 2009 the construction was ratified by the Danish parliament, and the German parliament approved the scheme on 18 June 2009.

In December 2010, it was announced that a tunnel would be used rather than bridges

In January 2011, a large majority of the parties in the Danish Parliament voted to support a tunnel-solution. However, national approval procedures in both countries need to be completed and, in Germany, this involves the application for a plan approval process. In Denmark, the project will require the passage in parliament of a Construction Act, and it is expected that all appropriate legislation will be completed by 2013. Construction of the tunnel is planned to begin in 2014 and is expected to last until 2020.

Criticism

Environmental impact

Critics believed that a bridge would create one more barrier for the water exchange to the Baltic Sea, which is dependent on the inflow of water from the North Sea. This oxygenated and salty water from the North Sea, crucial for marine ecosystems, reaches the Baltic Sea via the Skagerrak

. Studies carried out by Germany's Federal Agency for Nature Conservation demonstrated that about 70 percent of the water exchange between the North Sea and the Baltic Sea takes place through the Fehmarn strait. It is said that creating additional obstacles would further restrict the supply, causing deterioration of water quality and an increase in undesirable algae species on the Baltic coastlines. However, it was shown that no such additional obstacle appeared after the construction of the Great Belt bridges and the Øresund bridge.

Furthermore, the bridge would have been situated on one of the most important bird migration hotspots, and seriously influence rare and endangered bird species. The construction works of the bridge would affect already sharply regressing populations of marine mammals, such as seals and porpoises. In order to predict precisely far reaching consequences of the construction for the sensitive marine ecosystems, additional research was scheduled for 2009–2012.

Social concerns

Detractors believe that the construction of the fixed link and the resulting shift of cargo transport away from the existing ferry would mean a radical decrease in ferry operation and the loss of jobs. At the same time, employment connected to construction works would be only short-term. Furthermore, it is claimed that the project might be economically unjustified, as predictions of passenger traffic and goods transport may be overestimated and there is a considerable risk that the investment will not be recouped. Some suggest that the original plans for the bridge were drawn up during the Cold War
Cold War
The Cold War was the continuing state from roughly 1946 to 1991 of political conflict, military tension, proxy wars, and economic competition between the Communist World—primarily the Soviet Union and its satellite states and allies—and the powers of the Western world, primarily the United States...

and that since then traffic flow has changed profoundly, meaning that construction of a fixed link is no longer justified.
