The
Fehmarn Belt Fixed Link (, ) 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 – 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. This route is known in German as the
Vogelfluglinie and in Danish as the (literally, "bird flight line", indicating this major bird migration route).
