Duisburg Ruhr Weir

The Duisburg Ruhr Weir is a water control structure at the Ruhr with four adjustable gates that maintain the water level at approximately 82 feet (25 meters) above sea level for navigation purposes. A bridge spans across the top of the structure, allowing pedestrians and cyclists to cross while connecting to nearby locks.

Built between 1942 and 1956, the weir replaced earlier versions that controlled river flow where the Ruhr meets the Rhine. It was developed as part of modernizing water management infrastructure along this section of river.

The weir forms part of the Industrial Heritage Trail, displaying informational charts about the technical evolution of water management in the Ruhr region.

The best way to explore the structure is across the bridge on top, which offers good views of the gates and surrounding river landscape. Informational signs on site explain the technical functions and how water management operates in this area.

During extreme Rhine floods, the gates can rise completely above the water surface to prevent damage from floating debris. This mechanism protects the structure from the power of swollen rivers.
