The Rudersdorf Tunnel is the heart of the new Fürstenfelder expressway from Riegersdorf to Heiligenkreuz at the Hungarian border. The working group
“Swietelsky Tunnelbau – Granit – Swietelsky” was awarded the contract for Construction Lot 08 by ASFINAG at the end of 2018. This section, around 3 km long, consists of a cut-and-cover construction around 1 km long, a bored section of around 1.8 km built using mining techniques and a concrete groundwater insulation structure of around 0.3 km. The two tunnel tubes of the cut-and-cover section are 40% completed. The end of construction is planned for 2022.
