Innovative steel composite structure replaces 110-year-old truss superstructures
Information about launching of the bridge
The bridge crosses the arm of the Old Rhine and the Rhine foreland on a length of around 603 m, designed as continuous girder construction with over 17 spans and individual span widths of around 36 m.
The 2-tracked bridge is implemented as steel composite structure with above lying steel composite slab and two steel lattice girders underneath. The connection of the truss's upper chords to the reinforced concrete slab is an innovative development of already existing construction types.
The new bridge had to be erected whilst railway operation continued over one track. By assembly at the side and launching of the whole superstructure into its final position between construction stages 1 and 2, the construction time and thus the duration of single-tracked railway operation could be reduced significantly.
The joint venture Ed. Züblin AG - Plauen Stahl Technologie GmbH was mandated by DB Netz AG to implement the alternative proposal elaborated by SSF Ingenieure AG.
Launching of the structure into the final position is currently taking place between 16/01/12 and 30/01/12.
