The Thyratalbrücke is with 1115 m the longest bridge construction of Highway 38 . It is located in the district of Mansfeld-Südharz between the Heringen and Berga motorway junctions .
The overpass spans the Thyra valley as well as the state road 236 and the parallel railway line from Berga to Rottleberode at a height of a maximum of 40 m with 13 fields north of Bösenrode .
In the area of the bridge, the route of the motorway has a radius of 2500 m and a longitudinal gradient of 2.02%. The overpass was built between 2002 and 2005 at a cost of around 40 million euros.
Foundation and substructures
The western abutment and the westernmost pillar are built on piles . The remaining substructures have a flat foundation . The Y-shaped reinforced concrete pillars with a maximum height of 35 m have a full cross-section. To accommodate the bearings , the hexagonal cross-section at the pier head expands into two rectangular cross-sections with dimensions of 2.5 m × 3.5 m, which are connected to each other at the top by a steel tie .
superstructure
The one-piece superstructure of the composite steel bridge has a single-cell, open steel trough and a reinforced concrete deck connected with head bolt dowels . The cantilevered deck is supported by inclined struts. The construction height of the steel trough is 4.0 m, the construction height of the entire superstructure is a constant 4.65 m. The spans of the 13-span superstructure are 70 m + 75 m + 85 m + 9 × 90 m + 75 m. The deformation rest point of the bridge's longitudinal direction lies in the middle of the bridge, where three pillars carry the longitudinal forces that occur, for example from brakes.
execution
The steel superstructure was a steel trough with a launching nose in incremental launching inserted. Finally, the reinforced concrete deck slab was produced in sections with two formwork carriages.
