In the years 2019-2020, the S6 Semmering expressway in the area from Mitterdorf to Langenwang will undergo a general overhaul. In the course of this work, the existing noise barriers were renewed/raised and a total of around 2,500 m new noise barriers with an effective height of up to 5.0 m were erected. The noise barriers are located along both carriageways, directly at the edge of the S6 or on the embankment. They consist of highly absorbent aluminium cassettes and partly of transparent acrylic glass elements. The new pile foundation must be matched to the remaining foundations of the old wall. A large number of covered culverts and bridges require special solutions.
For the new noise barriers along the S6 and S36 highways, there is a uniform design concept by raum-werk-stadt Architekten, which must be taken into account in the permit design. The special feature of this concept is the construction of the walls with different numbers of bends in the cross-section. On behalf of ASFINAG Bau Management GmbH, convex ZT GmbH carried out the entire execution design as well as the preparation of the tender for the noise barrier S6 Langenwang – Mitterdorf.
