New Saale/Elster viaduct

Germany’s longest viaduct is being built over the Saale/Elster floodplain (to the south of Halle). When completed it will form part of the new line from Erfurt to Leipzig/Halle.

The line branches off in the course of the viaduct to serve Halle to the north. The superstructure is essentially in the form of single-span beams supported on piers positioned every 44 m, and continuous welded rails. Only at switches, wider sections and longer spans (over the River Saale and the B91 trunk road) is it necessary to use continuous beams with spans up to 70 m.

The flyover structure over the branch for the Erfurt‒Halle line spans 110 m and is in the form of a steel arch. This bridge will be built using the incremental launching method.

Technical data, viaduct:
- Design: prestressed concrete box girder
- Foundation: shallow foundations, constructed with the help of cofferdams
- Standard span: 44.00 m
- Total length: 8577 m
