Denmark is building an $8.2 billion tunnel across the Baltic Sea to Germany. The Fehmarnbelt is a thin, shallow Baltic sea channel separating Scandinavia and mainland Europe. Denmark is going to span it with a massive tunnel featuring a 4-lane highway and 2 rail lines. The Fehmarnbelt tunnel will increase transport efficiency, positively affect the environment, increase local tourism and improve connectivity. By its completion in 2029, the tunnel will break world records and change the economies of the region.
Denmark want to connect with Germany, not Eastern Europe (our Mexico)!
The crossing has been discussed for more than 30 years. At the beginning of that period, before the reunification of Germany, the only possible link was towards Hamburg, as going towards Communist East Germany was not a viable option. Although times have changed and Europe has been politically and economically reshaped in the meantime, the plans for the Fehmarn Belt Fixed Link has stayed the course. The Cold War era conceptualization of the Fehmarn Belt Fixed Link has been highly criticized, as some see connecting the two capitals of Copenhagen and Berlin and on a larger scale, a link from Scandinavia to the former Warsaw Pact countries as a priority of the upmost importance. A Gedser–Rostock Bridge, about 50 km (31 mi) further east, has been proposed as an alternative or to complement the Fehmarn Belt Fixed Link, as this alternative proposal would better connect eastern Germany including Berlin and places further east and south with Scandinavia.
