Wilnsdorf. The new construction of the A 45 Rinsdorf viaduct in the Siegen-Wittgenstein district is making great progress. Today, the eastern section of the structure in the direction of Dortmund, including piers and foundations, was moved transversely into its final position - a first in Germany on this scale. The project team of the construction consortium led by STRABAG is responsible for the innovative transverse shift: It is the technical highlight of the approaching end of the renewal of the neighboring Rinsdorf and Rälsbach freeway bridges. State Secretary Dr. Claudia Elif Stutz and Dirk Brandenburger, Managing Director Technology of Autobahn GmbH, watched the bridge section being moved, as did members of the Bundestag and leading representatives of the construction companies involved as well as the district and municipality. After more than 20 hours, the structure reached its final position at shortly before 5 pm.
The bridge was moved with the help of 24 hydraulic jacks - four on each of the six piers. To enable the load, which weighed several tons, to be moved, Teflon plates, which act as sliding pads, were installed between the specially prepared shifting tracks and the foundation base over the past few weeks. In order to reduce frictional resistance to a minimum, the plates were pre-treated with special grease. The slabs were moved in a total of 15 sections. The colossus moved forward 1.40 meters per section.
