A10 Tauern motorway at Eben
The large arc with a height of 7.4 m was erected on a section of 1.2 km along the Tauern motorway near Eben Nord, adjacent to a noise barrier. Also part of the rear was clad with absorbers in order to prevent reflections of noise from the motorway service area to the residential houses on the slope above.
Instead of a cost-prohibitive enclosure, which would have cost four times as much and would protect only one third of the section, an effective solution was developed, making use of the curved noise barrier. The large arc was optimised with an intelligent plug-in system for this building project to simplify maintenance for the operators.
