First tunnel machine delivered for Lyon–Turin

ITALY: Lyon–Turin has reached a new construction milestone after the first tunnel machine was officially delivered for works on the Italian side, ahead of a new excavation stage from Chiomonte.

TELT said the machine was handed over on March 11 at Herrenknecht’s plant in Germany and will now be transferred to the Chiomonte site in Italy’s Susa Valley.

From there, it is due first to excavate the Maddalena 2 access tunnel before continuing work on the southern tube of the base tunnel towards Susa.

Machine heads to Chiomonte for new excavation stage

The delivery marks a new works step on the Italian side of the cross-border section. It signals the shift from preparatory works to the next tunnelling stage.

The Lyon–Turin project centres on a 57.5-km cross-border base tunnel between France and Italy. The delivery enables the next phase of excavation from Chiomonte.
