Construction and refurbishment of Roppen Tunnel

The existing first tube of the Roppen tunnel (north tube) was operated in opposing traffic. This means in today‘s heavy traffic load, a threat to the smooth running traffic. To increase the safety of the A12 Inn Valley motorway the expansion of the Roppen tunnel was carried out to a modern, twin-tube tunnel system. In order to improve the safety standard of the entire tunnel system, after the construction of the second tube, the existing first tube was adapted as well.
