The Fehmarn Belt Fixed Link ( , ) is a planned immersed tunnel that is proposed to connect the Danish island of Lolland with the German island of Fehmarn, crossing the 18 kilometers wide Fehmarn Belt in the Baltic Sea, providing a direct link between northern Germany and Lolland, and thence to the Danish island of Zealand and Copenhagen, becoming the world's longest road and rail tunnel, potentially a major connection between Central Europe and Scandinavia, and shortening the travel time between Denmark and Germany to just 10 minutes by car and seven minutes by train.
