Safe journeys through the high mountains

The project was to reroute a 1.3 km stretch of the L 197 Arlberg pass road, which was at risk of rock falls and carriageway subsidence. To enable road users to use the route more safely, TEERAG-ASDAG constructed five supporting walls (1,700m³, up to 11m in height) for the section most at risk, in the steep alpine terrain above Stuben.

    • Rock removed soil class 6-7: 55,000m³
    • Specially coated surfaces 10-20cm: 1,500m²
    • IBO anchors: 3,200 m
    • Permanent ground anchors 950KN: 600m
    • Faced brickwork: 1,600 m²
    • Granite hard shoulder, 15/24 ROA1: 1,900m
    • Frost layer: 15,100 m³
