The Fehmarn Belt Fixed Link (Danish: Femern Bælt-forbindelsen, German: Fehmarnbelt-Querung) is a planned immersed tunnel that is proposed to connect the German island of Fehmarn with the Danish island of Lolland. This would cross over the Fehmarn Belt in the Baltic Sea – 18 km (11 mi) wide – hence providing a direct link by railway and highway between northern Germany and Lolland, and thence to the Danish island of Zealand and Copenhagen.
