Toulouse metro: tunnel boring machine Lise Enjalbert completes second breakthrough

Our tunnel boring machine, Lise Enjalbert, and its team have achieved a crucial milestone with the second breakthrough at the future Blagnac station.

The first breakthrough, spanning 950 meters excavated between Ponts Jumeaux and Sept Deniers Stade Toulousain Station, was celebrated with the "Red and Black Club" of Stade Toulousain Rugby.

More than 2,000 meters of the 4,136-meter tunnel have already been completed since the starting point at Ponts Jumeaux.

Next step: The teams are now preparing to reach the finish line at Puits Laporte for the spectacular operation of the machine's emergence from the ground!

Congratulations to Lise Enjalbert and her entire crew for this remarkable progress, and best of luck for the remainder of the journey!
