For a length of approx. 13.5 km the new construction of the A9 motorway was planned with two-way traffic. Due to the topographical conditions 6 tunnels had to be driven in, with lengths up to 2.8 km. Furthermore 12 bridge objects, partly very demanding in their construction, were built for passing the valleys, additional short tunnels in cut & cover method as well as the earthwork and road construction works required and the total electrical equipment for the route were included in the services.
