A TBM operated by Eiffage Génie Civil and NGE-BTP has made its third breakthrough on Toulouse Metro’s Line C project.
Following breakthroughs at Fondeyre and Ponts-Jumeaux stations, TBM Berthe de Puybusque has reached the future Lycée Toulouse-Lautrec station.
The TBM is now excavating towards its final destination of Raisin station.
Eiffage Génie Civil and NGE-BTP have deployed three TBMs on the project.
The Toulouse Metro Line C project involves building a new 27km metro line in the Toulouse metropolitan area, with 21 stops, including five interconnections with railway stations.
The Eiffage-led consortium was awarded Lots 1 and 2 civil engineering contracts by Tisséo Ingénierie.
Lot 1, which covers Line C from the Colomiers auxiliary structure, located 100m from Colomiers Gare station, to the Laporte auxiliary structure, includes the design and construction of a 3.85km tunnel, three stations and four ancillary structures between stations. It also includes the construction of three shafts connecting the shafts to the tunnel.
Lot 2 covers the section from the Laporte auxiliary structure to Raynal station. The work includes the design and construction of an 8.416km tunnel, six stations, five auxiliary structures at intersections and a connecting tunnel to the maintenance site. It also includes the construction of nine shafts connecting the shafts to the tunnel.
The 27km-long line will stretch from Colomiers station in the north-west to Labège station in the south-east, with 21 metro stations along its route.
