Soletanche Bachy France, working with Soletanche Bachy Tunnels and Bessac, alongside others within the Thaumasia joint venture, carried out surveys and civil engineering works for the 3.2km underground section under a contract involving a 9.8-metre-diameter bored tunnel, four underground stations, entrance and exit shafts, fittings and finishing, equipment, and testing.

The tunnel is being built to efficiently serve the city centre while safeguarding its architectural heritage.

Soletanche Bachy faces the challenges of complex geology with highly variable soil and a small construction site in the centre of the city with shallow foundations and particularly sensitive built structures.

The tunnel, special works and major works are completed.

The finishing, equipment, surface work, and testing the trams in the tunnel is underway.
