Between the municipalities of Langeneichstädt in the north west and Stöbnitz in the south east, the new Erfurt-Leipzig/Halle line crosses the shallow Stöbnitz Valley containing the Stöbnitz river and two ditches. The Stöbnitz Viaduct takes the line across this valley.

In accordance with the overall plan for the supporting structure of sectional girders in concrete, a distance between pillars of 24 m (22 m for the end span) and 6.50m for the shear legs has been set. A viaduct length of 297 m emerges.

The two-track superstructures are formed by 2 x 5-span continuous girders and 2 x 2-span continuous girders. The supports are rounded columns in reinforced concrete. Deep foundations are required in the shale for the supports and abutments.

Instead of the superstructure of rolled steel girders in concrete in accordance with the master plan, a single-webbed longitudinally prestressed T-beam is used. Given the selected construction thickness of 1.25 metres, the maximum slenderness ratio is l/19.2, which ensures the required degree of robustness easily. The 2.56-metre wide traditionally reinforced cantilevers enhance the slender appearance of the superstructure. There is no need for under-deck beams in the bearing axes as in the master plan.

The edge capping on either side of the track is as in the DB master plan. Continuous cable troughs are required on both sides of the bridge because cables cannot be laid under the slab track from one side to the other.

Successful project collaboration with EPLASS:

Since EPLASS is already being successfully used for all the single projects of the German Unity Project No.8, it will also be used for the project organization of this subproject.

To facilitate the complex construction management in a central system, the project participants decided to work with the internet based project collaboration platform EPLASS. All processes are easily accessible for all project participants at any time and any place. Everything from the correspondence, to the construction reports, structural analysis, check reports and claims are organized, reviewed and archived within EPLASS. The project participants consists of the above named joint venture, the German Railway (DB AG), external designers, checking engineers, geotechnical engineers and the building inspection. The federal railway authority is also involved in this project.
