$8 Billion Tunnel Will Connect Denmark and Germany, Cutting Travel Time in Half
Despite being bordering countries, there arenโt many direct routes between Denmark and Germany. To ameliorate this, the two countries have embarked upon an ambitious collaboration: the Fehmarnbelt tunnel. This tunnel will dramatically reduce travel times between major cities like Copenhagen and Hamburg, and will serve not only as Denmarkโs largest infrastructure project but also the worldโs longest immersed tunnel at 11 miles.
