A Technical Feat Applauded On Site<\/b><\/p>\n

The successful breakthrough at the Limayrac \u2013 Cit\u00e9 de l\u2019Espace station adds to a series of key milestones: after passing through the Ormeau station last October, followed by the installation of the 1,000th ring segment in March, this marks another victory for the dedicated teams.<\/p>\n

Local officials, nearby residents, and project professionals were present to witness the breakthrough live, emphasizing the significance of this moment for both the community and project stakeholders.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Target: 2025 \u2013 4.2 km of Tunnel<\/b><\/p>\n

The next stop will be C\u00f4te Pav\u00e9e station, before the final arrival at the Saint-Sauveur shaft, scheduled for November 2025. This will mark the completion of the 4.2 kilometers of tunnel for section 4.<\/p>\n

Each meter gained underground is a step forward toward the city of tomorrow. The tunnel boring machine Marguerite de Catellan\u2019s breakthrough at Limayrac \u2013 Cit\u00e9 de l\u2019Espace is not just a technical milestone \u2014 it\u2019s a strong signal that the Toulouse metro is advancing with precision and passion.<\/p>\n<\/div><\/div><\/div>

Projects Certified with Ultra-Low-Carbon Concrete EXEGY\u00ae by BESSAC<\/b><\/p>\n

As a reminder, as part of the Line B extension project, Bessac is producing all 2,850 tunnel lining segments using ultra-low-carbon concrete EXEGY\u00ae by Bessac, in collaboration with the materials departments of VINCI Construction and Soletanche Bachy. The result: a 40% reduction in CO\u2082 emissions compared to traditional concrete!<\/p>\n

For section 4 of Line C, part of the diaphragm walls for the shafts were also made with EXEGY\u00ae ultra-low-carbon concrete.<\/p>\n
