Vienna, 21 September 2020---The Austrian construction group STRABAG has been awarded the contract by ÖBB-Infrastruktur AG for the rehabilitation and modernisation of the Karawanks Railway Tunnel (Lot KRT 1 Karawankentunnel – Construction Technology). The 8 km long tube, which was built over 100 years ago, is currently on a two-track layout. To comply with modern safety standards and thereby extend the service life by a further 30 years, the tunnel is being rationalised to single track only. The contract value amounts to € 68.4 million. Work is scheduled to last one year, including a nearly seven-month period of full closure.

Modern tunnel – historically listed portal structures
The construction work commenced with the cleaning of the tunnel interior. Previous renovation layers are being partially removed and replaced with a new shotcrete lining. Existing chambers are to be converted and remodeled into technical rooms. The entire floor of the tunnel will be dismantled and rebuilt. Future drainage will take place via laterally laid drainage pipes. The famous, historically listed portal structures will remain in place and will also be renovated as part of the project. The reopening of the entire tunnel is scheduled for September 2021.
