Municipalities and construction sites

The main Italian building site for the work on the cross-border section of the Turin-Lyon tunnel is in Chiomonte, as detailed in the Building Site Project Variant approved in 2018 by the CIPE. However, six other municipalities between Val di Susa and Canavese are affected, to varying degrees, by parts of the work.

In particular, the other sites are affected by the transformation or storage of inert materials that, after careful checks carried out by competent authorities, are permanently stored or used for the restoration of other industrial areas.

CHIOMONTE

Chiomonte is a Val di Susa municipality with approximately 900 inhabitants where, in February 2017, the 7km-long excavation of the geognostic tunnel and access adit on the Italian side of the cross-border section of Turin-Lyon was completed. As detailed in the Building Site Project Variant approved in 2018, excavation works for the base tunnel in the direction of Susa will start from here, making Chiomonte the largest Italian building site for the project.

GIAGLIONE

Gaglione is a Val di Susa municipality with approximately 600 inhabitants. This centre is adjacent to Chiomonte and, for this reason, it is impacted by the enlargement of the construction site of the cross-border section of the new international railway line.

GRAVERE

Sited on a hill running along the left bank of the Dora Riparia, the town has roughly 700 inhabitants. Although not directly involved in the works for the base tunnel, it is located near the Chiomonte site and for this reason it has been included in the environmental monitoring plan for the protection of the territory and citizens.

SUSA

It is the main center in the Val di Susa, with roughly 6,000 inhabitants. This is where the international station designed by architect Kengo Kuma is to be built. The station will be a stop on the Turin-Lyon line and a resource for tourism in the Alpine areas.

SALBERTRAND

Municipality of the Val di Susa with roughly 600 inhabitants where the exploitation site for the excavation materials extracted from the base tunnel will be built. The factory will be built in a rail yard area which is currently abandoned and which was already used to stock industrial equipment during the construction of the Turin-Bardonecchia motorway.

CAPRIE

Caprie is a town in the Lower Val di Susa with roughly 2,000 inhabitants. The smaller depot necessary to store part of the excavated materials extracted from the base tunnel will be housed in a quarry. Thanks to the construction of a new rail link, the materials will be transported exclusively by train.

TORRAZZA PIEMONTE

Torrazza Piemonte is a municipality in the Canavese with roughly 3,000 inhabitants, sited near the Dora Baltea. The main site for the storage of non-reusable excavated materials will be built here. The material will be transported via a mixed system that will use both the existing railway and a dedicated conveyor belt.
