The Buckelbrücke is a 79 meter long and 3.5 meter wide pedestrian and cyclist bridge in the inner harbor of Duisburg and the only humpback steel bridge in the world.
It was designed by the Stuttgart professor Jörg Schlaich and built by the Duisburg steel company Raulf in 1999.
location
It connects the Garden of Remembrance (Altstadtpark) on Yitzhak-Rabin-Platz with the northern harbor promenade, the Duisburg Marina and Schifferstrasse.
technology
With 14 individual, movable and scale-like interconnected concrete elements, the 150-ton bridge bridge spans the harbor basin. The construction is held in place by steel cables attached to four 20 meter high pylons. At the end of the steel cables there are pulling devices so that the pylons can be pulled inland. The bridge rises by up to eight meters, the moving individual elements of the articulated chain move more than three meters apart, the arch spans upwards at an angle of 45 degrees - the bridge makes a cat's hump.
The hydraulic pulling device is operated from the swan gate bridge . The bridge is theoretically still accessible during the six-minute tensioning and relaxing process, but for safety reasons it is closed to pedestrian traffic.
In the normal state, the hump arches only 1.10 meters above street level, but when it is stretched it can be raised up to 10.60 meters above normal water level.
