Kagraner Brücke, Road bridge in Donaustadt, Vienna, Austria

The Kagraner Brücke is a concrete structure crossing the Alte Donau in Vienna, connecting the districts of Kagran and Kaisermühlen. It features eight welded steel beams supporting a wide concrete deck designed to handle cars, streetcars, and pedestrians.

The original bridge was destroyed during the Second World War, rebuilt in 1945, and finally replaced in 1977 with a new structure. The new construction was necessary as traffic between the districts increased and the city required modernization.

The bridge links two districts and serves as part of daily life for many Vienna residents. Streetcars, pedestrians, and cyclists cross it regularly, making it a point where different neighborhoods meet and people connect.

The bridge is easily accessible from the Alte Donau U-Bahn station and offers clear pathways for pedestrians and cyclists. It is best explored during dry weather when the bridge and surrounding paths are most comfortable to use.

The 1945 steel spans were built from steel plates already stored in Waagner Biro's workshops, as post-war supply shortages forced planners to adapt the design to available material. The 1977 widening was carried out in two stages so traffic could keep crossing: only one overnight closure, from a Saturday to a Sunday, was needed to pour the concrete between the two new structures.
