One of the highest railway bridges in Europe gets a new steel superstructure

At 96 m, the Jauntal Bridge in Austria is one of the highest railway bridges in Europe. In the course of the construction of the new double-track Koralmbahn railway line, the existing single-track structure of the Jauntal Bridge will be upgraded to a modern, double-track steel truss composite structure. Donges SteelTec has been awarded the contract for the manufacture, delivery and assembly of the steel superstructure. The 3300 tonne steel structure will be manufactured at the Darmstadt plant. The 428 m long steel structure will first be assembled in three segments on a pre-assembly area below the existing bridge. The three structural elements are then moved transversely and longitudinally one after the other. In the process, the old and new supporting structures are connected to each other and the existing bridge is also pushed out.

The spectacular assembly work high above the river Drava begins in early January, when the first of the three segments of the new superstructure is first shifted transversely and then coupled to the existing structure. The first longitudinal shift will then follow in February. A technical and logistical challenge for our employees and, after the Danube bridge in Linz (bypass bridges), another milestone for our company in neighbouring Austria.
