Toulouse Metro - Line B connection.

18/05/2024

Work on the Connexion Ligne B is progressing! On Wednesday 15 May - after three months of work - the TBM Clemence Isaure - 30 m long, 5.28 m in diameter and reconditioned by the BESSAC company based in St Jory - completed its first section under the Canal du Midi. The digging of the first tunnel, 260 m long and with an internal diameter of 4.66 m, is now complete. The TBM will start digging the second tunnel at the end of June. 

  

Two parallel tunnels will then be dug by autumn 2024! They will enable the Toulouse metro to cross the Canal du Midi and Avenue Latecoere. These underground structures make up lot 2 of the Connexion Ligne B project, which will link the current terminus of line B of the Toulouse metro with the future line C, due to come into service in 2027. 

  

The TBM will now be transported to the Ramonville structure to complete the second section. It will start its new run, parallel to that of the first tunnel, at the end of June, and should finish digging in September. 

This project, 100% made in Occitanie, is being carried out on behalf of SMAT, with great pride by the BESSAC, Soletanche Bachy, GTM Sud-Ouest TP GC consortium.
