The valley bridge Wiesental is a 252 m long bridge on the federal highway 73 at kilometer 4.8.
The structure is located near Suhl between the Suhl-Zentrum and Suhl-Friedberg motorway junctions in southern Thuringia . It spans the Wiesental south of the Suhl district of Neundorf at a maximum height of 40 m with six fields. The overpass was built with two separate superstructures for the directional carriageways between 2002 and 2004 at a cost of around 7 million euros.
Substructures
The bridge piers with a maximum height of approximately 38 m are divided into two slender individual columns that are connected to one another by cross bars. The supports have a rectangular full cross-section and decrease over the height with a ratio of 1:70.
Superstructures
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 box girder cross-sections with a constant construction height of 3.15 m. The prestressing consists of a mixed construction with internal and external tendons .
The total span for the six-span bridge is 252.0 m, the two end spans span 36.0 m and the four central openings 45.0 m.
execution
The bridge superstructure was constructed using the incremental launching method.
