As western continuation of the Baltic Sea motorway from Lübeck to Stettin, motorway A20 will be an important east-west link in the North of Germany and connect the two German seaports with the hinterland.As currently there is no crossing over river Elbe west of Hamburg, the new Elbe tunnel will significantly relieve motorway A7.The project “Elbe Crossing A20” starts in Lower Saxony at the future motorway interchange A 20/A 22/A 26 or junction K28 south of Drochtersen and ends in Schleswig-Holstein at junction A20/B431 north of Kollmar. This construction section has a total length of 8,562 metres, of which 5,671 metres are a 2-tube shield tunnel with an inner diameter of 12.20m.With a total length of 6.5 km (incl. entry and exit troughs), the Elbe crossing will be the longest underwater tunnel in Germany.
