Rheinufer Tunnel

The Rheinufer Tunnel is a road tunnel in Düsseldorf, Germany. Built between 1990 and 1993 at a cost of 57 million Deutschmarks, the tunnel is part of the B1 German federal road. At long, it is the sixth longest inner city tunnel in Europe.
The tunnel runs under the Rheinuferpromenade near the right hand bank of the Rhine. The impressive southern entrance of the tunnel is marked by a tall building, the Düsseldorf Stadttor. The northern entrance is just south of the Oberkassel Bridge.
