The Brenner Base Tunnel is the centrepiece of Priority Project 1, railway axis Berlin-Verona/Milano-Bologna-Napoli-Messina-Palermo.
The 55 km cross-border tunnel across the Alps will remove a major bottleneck for both freight and passenger transit between Austria and Italy.
This project covers the excavation of the exploratory tunnels from several fronts. The studies will serve to assess the costs and duration of the construction, as well as to assess more accurately the risks of the overall project.
Apart from minimising the geological risks, the construction of the exploratory tunnels will also serve as an access and drainage system during the works and operation of the main tunnels.
State of progress on 31 December 2012:
In Italy, the intermediate access tunnel in Mauls/Mules and the Aica-Mauls/Mules exploratory tunnel were completed in 2009 and 2010 respectively. The excavation of the exploratory tunnel is currently continuing towards the north through the Periadriatic fault.
In Austria, the exploratory tunnel stretch from Innsbruck to the lateral access in Ahrental was completed in 2012, and further excavation is on-going. Progress is also taking place at the lateral access in Wolf: the tunnels to access the disposal site at Padastertal was completed in 2011, and the tunnel to access the site directly from the motorway was finalised in 2012.
