U2 Donaustadtbrücke

The Donaustadtbrücke is an subway/underground railway bridge over the Danube and the New Danube. The structure over the Danube is constructed as a cable-stayed bridge with an impressive 85 m-high A pylon. The design was created by the civil engineer Alfred Pauser in collaboration with the architects Wilhelm Holzbauer and Heinz Marschalek. Initially used as an alternative route for cars, the bridge has since 2010 been used as a route for the U2 subway line.
