Initial situation

The cantonal road to Val d’Anniviers (Valais) and the industrial area below are endangered by frequent rockfalls. The rock face above is exceptionally steep. Therefore, a rockfall can affect the entire width of the cantonal road. To protect the seven-meter-wide roadway, both lanes were covered with netting.

Description

A rockfall protection system with an energy absorption of 2000 kJ was installed. The topography and the need to ensure a lightroom profile, especially in the event of rockfall, required a unique solution: the posts are between 10.0 and 13.5 meters long.

The costs for the solution are far below those for a solution from reinforced concrete.
