Completion of the Gleinalmtunnel

The A9 Phyrn motorway is part of a 230 km long north-south transit axis between the crossroad Voralpenkreuz and Spielfeld on the border to Slovenia. It is thus an important north-south transversal, not only in Austria but also in the European transport network. The Gleinalmtunnel is situated between the motorway junction St. Michael and Deutschfeistritz and belongs to longest two-tube road tunnels in the world. DÜRR Austria was awarded with the contract in December 2015 and the traffic release of the A9 took place in December 2019 after a nearly three-year project period.
