Initial situation

Due to the constant rockfalls that affected traffic and tourists visiting the area, it was decided to implement a protection system to control rockfalls in a 580 meters long section.


The technical specifications defined the length of the area to be protected at 580 meters. The flexible barrier had to have an energy absorption capacity of 3000 kJ.

Watch the video for a flight along this rockfall barrier.
