Brenner Base Tunnel - Mules 2-3 Lot
The contract refers to the construction of the main section of the Italian side of the Brenner Base Tunnel, the joint Italian-Austrian project to build a railway tunnel that will connect Italy to Austria.
The work is part of the project to upgrade the Munich-Verona railway line. Once completed, it will be the longest underground railway link in the world.
The Mules 2-3 Lot involves building approximately 65 kilometers of tunnels, of different sections, (an exploratory tunnel, 2 main line tunnels, cross tunnels and the emergency stop, including the related access tunnel), partly excavated with the traditional method, and partly with the use of TBMs.
