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.
