Last week TBM Aby broke through at the Vitry Center station on Line 15 South, on the Grand Paris Express. The TBM was first assembled and then launched in  June 2019 by the  Consortium Horizon  which consists of Bouygues Travaux Publics,  Soletanche Bachy and BESSAC . The TBM began its journey at the Arrighi shaft in Vitry-sur-Seine and tunnelled towards Villejuif Louis-Aragon station (4.6 km). 

After crossing the Ardoines station and the Bel Air structure, Aby is now approaching its final destination, where its arrival is scheduled for the 3rd quarter of 2021.For further information please click here and fr/127 for the tunnelbuilder archive and also visit https://www.societedugrandparis.fr. 10/21.
