Elbe Bridge Riesa
Single-track trough arch bridge
From axis 10 – 40 as a river bridge with a 101.40 m long arched bridge crossing the Elbe River and from axis 40-70 as a foreland bridge. The bridge consists of two external, parallel-girder main girders with intermediate orthotropic roadway slabs. The ballast bed is bounded laterally by ballast edge girders. Walkways with integrated cable ducts are provided on both sides between these edge girders and the main girders. The stiffening girder of the arched span bridge is fabricated as a double T-profile, which merges into a box girder cross-section in the area of the arch intersection points. The two arches are connected by Vierendeel truss. The steel structure is fabricated in sections on a pre-assembly site and then moved longitudinally into the end position using the incremental launching method. For this construction stage, both three-span girders must be coupled.
