S 16 Arlberg road tunnel – partial renovation 1 and escape route
Civil Engineering Underground engineering
The nearly 14-kilometre long Arlberg road tunnel between St. Jakob in Tirol and Langen in Vorarlberg is the longest road tunnel in Austria and the only winter-safe east-west connection between Tyrol and Vorarlberg. After 35 years of use, the renovation was primarily driven by the need for greater safety. Jäger Bau was contracted by “ARGE Sanierung Arlberg Bau” (PKE-Jäger-BeMo-Hinteregger) to conduct all above ground work.
