France and Italy sign Lyon – Turin accord | International Railway Journal
The French and Italian governments hope to secure up to 40% of the funding required for the project from EU sources. ...

The 140km line will have 87km of tunnels including a 57km twin-bore base tunnel between St Jean de Maurienne, France, and Chiomonte in Italy. The cross-border section extends for 18.1km on the Italian side, 12.5km of which will be in the base tunnel. Beyond the Italian portal, there will be a 3km link to the existing line at Bussoleno, including a 2.1km tunnel and a new station at Susa. ...

The line is expected to open in 2028, reducing Lyon – Turin journey times from 3h 30min to 1h 47min.

Estimated costs:
Total: €26bn
Base tunnel: €8.5bn

A tunnel about as long as the Gotthard Base Tunnel.

Lyon – Torino TBM completed - Railway Gazette
Tunnelling is expected to get underway towards the end of this summer at Saint-Martin-la-Porte in France on the test bore for the base tunnel planned to carry a high speed line between Lyon and Torino. This will use a 12 m diameter TBM built by NFM Technologies at Le Creusot which was named ‘Federica’ on January 14.

Seems like they are going ahead with it.

Macron pauses Lyon - Turin high-speed project because of a EUR 10-billion shortfall. This project is estimated to cost EUR 26.1 billion, and this pause is to reassess whether to continue with it.
