Repair of the national highway A3 MurgWalenstadt section/Switzerland

The Murg–Walenstadt section of the motorway is located in a topographically challenging area along the Lake Walen. The section cuts through the southern side of the valley and comprises five tunnels, three large viaducts and numerous engineering structures such as bridges, retaining walls, protective structures and noise protection structures. The repair work is to be carried out at night, thereby enabling full capacity for traffic during the day.
