The New Elbe Tunnel, often simply called Elbe Tunnel in English is the Elbe river crossing in northern Germany. The Elbe Tunnel has a length of 3.1 kilometers (1.9 mi). As a part of the Bundesautobahn 7 in Hamburg, the tunnel forms a connection between Schleswig-Holstein (and on towards Denmark) to the north and Lower Saxony to the south. It has 8 lanes in 4 bores. The newest, fourth bore is the only one to feature a hard shoulder, minimizing congestion due to broken down vehicles.
