The 255 m long Rhine bridge between Hard and Fußach must therefore be adapted to ensure the primary framework conditions for flood protection. In addition, the standard cross-section of the supporting structure no longer meets today's traffic engineering requirements. The new Rhine bridge Hard - Fussach, which is planned as a 4-span steel composite bridge with a dissolved cable structure, has three new piers, of which two of the pylons support the cable structure. The structure (4-span girder) has span lengths of 50 m, 125 m, 50 m and 31,6 m. This results in a total span of 255.60 m. The stiffening of the structure above the main span supports is in the form of a harp-shaped span. Due to the low height of the four masts and the resulting shallow inclination of the cables, this is a resolved cable structure that helps to optimize the overall stiffness in the area of the river piers. The architecturally designed steel masts, which consist of a rectangular steel box cross-section, have a height of approx 12m. Construction phase Substructure: Construction work began on schedule at the end of June 2020 with the creation of the site set-up area and the establishment of the construction site. In September 2020, work on the substructure of the bridge was carried out at full speed in the foreland of the Rhine. The winter half-year 2020/2021 was decisive for the construction schedule, as important work could only be carried out during periods of low water discharge. The construction of the substructure and the auxiliary piers in the area at risk of the Rhine were carried out in the winter half-year and thus during periods of low water discharge.
