Bouygues Travaux Publics was selected by La Société du Grand Paris to carry out the public works on line 15 South of the Grand Paris Express. The civil engineering work will concern the stretch between the stations of Villejuif Louis-Aragon and Créteil l’Échat. 

The work concerned will include the civil engineering for four stations (Créteil l’Échat, Vert de Maisons, Les Ardoines and Vitry Centre), the excavation of a two-way tunnel and the entry well for two tunnel boring machines (Arrighi brownfield, in Vitry-sur-Seine), and the realisation of five associated structures. The objective of this new line is to relieve traffic pressure on other public transport lines.
