Montets road-rail tunnel

The Montets road-rail tunnel is used by trains on the Chamonix-Vallorcine line and also allows road traffic to avoid the Col des Montets mountain pass when there is heavy snowfall. The aim of this contract is to upgrade the tunnel's level of leaktightness, expand its diameter, and bring it up to standard in terms of safety and compliance with road and rail guidelines.
