Toulouse Metro: TBM Berthe de Puybusque reaches a new milestone

Following the Fondeyre and Ponts-Jumeaux stations, the Tunnel Boring Machine (TBM) Berthe de Puybusque has successfully completed its third breakthrough, reaching the future Lycée Toulouse-Lautrec station.

Nearly 1,100 meters have been excavated out of the remaining 2,122-meter stretch between La Vache Gare – Le Grand Marché and Raisin stations.

Berthe is now heading towards Raisin station, the TBM's final destination, where our teams are already preparing for the machine's extraction operation.

Wishing Berthe de Puybusque and her crew all the best for the rest of the journey!
