On the 29/05/2023 TBM 7, named Houda, broke through at the Becquerel manufact in Sevran, Lot 2, Line 16, as part of the Grand Paris Express route. The contractor consortium is NGE - BTP - Webuild. The 5.8 km section excavated by Houda is the largest on Line 16.  

The TBM will now restart toward the future Sevran Livry station which is about 850m long, before making its final breakthrough at the Mare au Chanvre structure at the end of the year, where the TBM 8, named Mireille, is currently being dismantled after breaking through last month.
