The Rheinufer Tunnel ( or "Rhine Bank Tunnel") is a road tunnel in Düsseldorf, Germany. 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 Rhine Promenade near the right hand bank of Rhine. The impressive southern entrance of the tunnel is marked by a tall building, the Düsseldorf Stadttor (city gate). The northern entrance is just south of the Oberkassel Bridge. See also Kunst im Tunnel Transport in Düsseldorf Buildings and structures in Düsseldorf Road tunnels in Germany Tunnels completed in 1993
