Chiomonte construction site

Excavation of the 12.5 km base tunnel in Italy, from Chiomonte to Susa, and construction of the junction on the A32 motorway

In Chiomonte there is the largest Italian construction site for the Lyon-Turin railway line. Since 2012, it has been a site of strategic national interest and is the Italian access route to the base tunnel.

To guarantee the safety of workers and citizens, in 2018 the CIPE approved the variant design that provides for the start of the base tunnel excavation on the Italian side from the Chiomonte construction site – already operational for exploratory work – instead of from Susa as initially planned.

The site measures 12 hectares and is located in the municipalities of Chiomonte and Giaglione, under the viaduct of the A32 motorway.
