Rerouting of L 197 Arlberg pass road

Klösterle, Austria / 04.2014 - 11.2015

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.
