The contract is for Lot 2 which covers the access tunnels between Saint-Martin-La-Porte and La Praz in the French Alps. The French section of the works accounts for 45km of the 57.5km-long Mont Cenis base tunnel, and the S2IP consortium will be responsible for project managing two 22.1km single-bore parallel tunnels.


Systra already has three contracts for the overall project:

• project management assistance for traffic and socio-economic studies
• land acquisition in France, and
• reviewing pre-project and final studies.

Systra has been working on the project since 2002, including studies, preparatory assignments, and project management of the Maddalena exploratory tunnel.

When the Lyon - Turin link opens in 2030, the journey time will be cut from 3h 43min to 1h 47min. Around 4.5 million passengers are expected to use the line each year.
