The Werratal Viaduct is a 432 m long bridge on the Federal Highway 73 .
The prestressed concrete beam bridge , which lies between the Eisfeld-Nord and Eisfeld-Süd junctions, spans the flat valley of the Werra near Eisfeld , the federal road 89 from Eisfeld to Themar , the parallel Werrabahn and two farm roads at a maximum height of 30 m . The building, which has a curved floor plan, was built with two separate superstructures at a cost of around 19 million DM between the years 2000 and 2002.
The full cross-section of the maximum 26 m high pillars is V-shaped. To accommodate the bearings , the octagonal cross-section at the pier head expands into two rectangular cross-sections with the dimensions 1.9 m × 2.0 m.
The two adjacent superstructures of the prestressed concrete bridge have the continuous beam as a structural system in the longitudinal direction . In the transverse direction there are single-cell box girder cross-sections with a constant construction height of 3.6 m. The total span of the nine-span bridge is 432 m. The two edge fields span 41 m, the seven inner fields have a span of 50 m. The pre-tensioning consists of a mixed construction with internal and external tensioning cables . The bridge superstructure was constructed using the incremental launching method.
