Between the two Vorarlberg communities Hard and Fussach a new state-of-the-art bridge will replace the old Rhine bridge, which has been classified as critical from a flood protection perspective.
The new bridge will increase flood protection and at the same time it will be able to meet the modern traffic requirements - two traffic lanes, a bus lane and a foot and cycle path are planned for the 255 metre-long bridge.
The bridge is of the "extradosed bridge" type - a type in which the guidance of tendons runs outside the cross-section of the deck girder.
Another special feature is the geometry of the piers, which "unfold" from a rhombus to a rectangle from bottom to top.
Hard-Fussach is a 4-span steel composite bridge with a dissolved cable structure. It has three new piers, of which two of the pylons support the cable structure.
Once the traffic has been rerouted via the new bridge, the old bridge, dating back to the 1970s, will be demolished. See video, produced by Habau Group, on YouTube.
