The Thyratalbrücke North of Berga, close to Bösenrode, reaches the Western abutment after the last adjustment on 11 October 2003. Thus, this bridge with a length of 1115 meters is the longest highway bridge in the course of A 38. 12 Y pillars, with a maximum height of 40 meters, spans the Valley of Thyra, steel structure as well as the highway and the railway line from Berga to Stolberg/Harz. The reverse thrust bearings for roller bearings be replaced in October/November 2003, the concrete road surface is then applied. The bridge is 21 feet wide with the steel beams and widened to 4-meter, thus, the bridge will reach width 29 m. The span from pillar to pillar is: 70 m - 75 m - 85-9 x 90 m and 75 m from West to East 1115 metres =. (Information provided by Manfred undRaik Schröter) The reverse thrust bearings against bearing on the bridge piers are exchanged until March 2004. From March until November, the concrete foundation for the road surface will be built. To be mounted two sled-like boarding halls on the steel body, where the concrete work on the stage you want to go. 13 000 m3 reinforced concrete is estimated for the track. In the Middle, thickest area, the concrete runway will be 37 cm strong. (information provided by Manfred and raik Schröter of the 26.01.2004) Executive Baufrima: Bilfinger &amp; Berger Information by Heidi Zahir: For the bridge, there were various taboo zones which were to note when planning in the Thyratal. So many mammals and bats settling along the West slope of the Thyra. In addition, the environmental planning demanded that no structural interventions were allowed to be made in the area between the Thyra and the parallel millrace. The pillars of the bridge were placed as far as possible from the riparian areas, to avoid intervention in the area of the river and the flood plains. Various farm roads were built for the construction. So was for the Western abutment bridge which created a new economic way, for the Eastern abutment was an existing way to moved. The nine pillars of West Road could be reached via Baustraßen with behlfsbrücken about the Thyra and the millrace. After the completion of the bridge end of 2004 were dismantled the Baustraßen and the areas utilized recultivated. The access roads to the abutments remain. A gravel lawn for future entertainment and maintenance of the bridge is created under the building. Test drilling had revealed that for the Thyratalbrücke sufficiently viable soil layers (semi-solid alluvial loams,) medium concentration near the surface are densely-bearing gravels and decomposed and entfestigtes rock. The soil allows for shallow foundations of abutment and Pier. The superstructure rests on twelve steel concrete pillars, which are designed as a hollow pillar with one-piece shaft and hexagonal cross section. The pillars have a Y-shape. Insert the steel trough occurred from the Eastern abutment in the built. The superstructure stem beak is provided with a circa 30 metres long. The building cost approximately EUR 35.7 million.
