Fréjus Road Tunnel

Savoy – France | Piedmont – Italy

The construction project

As part of the Fréjus Road Tunnel – Second Tube (G2) project, Hodapp GmbH & Co. KG, in cooperation with Hodapp France SARL, supplied and installed a total of 320 specially manufactured fire barriers.
The doors serve to securely close off escape and rescue routes and technical rooms, ensuring maximum safety for tunnel users and emergency personnel in the event of an incident. Due to their high-quality workmanship, tested fire resistance, and high pressure resistance, they represent an essential component of the technical tunnel infrastructure.
