The Schwanentorbrücke is a vertical-lift bridge in Duisburg, North Rhine-Westphalia, Germany, that crosses the Duisburg Inner Harbour. The bridge can be vertically raised to allow cargo ships to access the inner city, and lowered to allow cars, trains and pedestrians to cross. The bridge is named after the Schwanenturm that protected the city walls in the 13th and 14th centuries.
