Safety for rail and road.
PORR's task in this project was to protect the Intschi tunnel entrance on the Gotthard-Nationalstrasse from falling rock and landslides. To this end, rock anchors were drilled and steel mesh nets installed. In addition, PORR constructed a massive supporting wall above the southern tunnel entrance to protect the Gotthard railway line.
Safely through the mountain.
