Weir 1

Weir 1 is a footbridge combined with a water control structure spanning the Danube in Vienna. The prestressed concrete construction manages water flow while allowing pedestrians to cross the river above it.

Weir 1 was built in 1978 as a breakthrough in Vienna's flood protection along the Danube. The structure introduced new techniques to control water levels during periods of high flow.

Engineers and students regularly visit Weir 1 to study its dual-purpose design, which demonstrates the integration of water management with public transportation needs.

The structure is easily accessible and offers clear views of the Danube and its water management systems. You can walk across and observe from both sides how the weir and bridge work together.

The structure demonstrates how engineers combined flood control and pedestrian traffic in a single construction. The prestressed concrete technique made it possible to create a slender design that requires less space than traditional methods.
