After a construction period of three years the Arlberg Tunnel on the S16 Arlberg Road (Austria) was officially reopened to traffic.
Having a length of approx. 15.5 km, the longest road tunnel in Austria was equipped with 37 additional escape routes and another eight emergency lay-bys. In total ASFINAG invested EUR 154 million in the safety upgrade of the tunnel, and has applied state-of-the-art technologies (high-pressure water mist system, thermal scanner at both portals, AKUT system, etc.) in the tunnel.
ILF Consulting Engineers was entrusted with the project management and the supervision of the electromechanical installations and control systems.
