The tunnels Tanzenberg (2.5 km long), Oberaich (0.2 km), Massenberg (0.4 km), Bruck (1.2 km), St. Ruprecht (0.7 km) and Niklasdorf (1.3 km) belong to the Bruck tunnel chain in Austria. Since 2007, the ASFINAG (the Austrian Motorways Authority) has redeveloped and upgraded the chain of tunnels along with all the bridges and open areas of terrain belonging to it. These activities at the Semmering major project expressway S 6 were completed at the end of April 2016 with an investment cost of around 220 million euros.
