The future line 15 of the Grand Paris Express will be the longest metro line of the region and will above all benefit the inner city districts of Paris (Hauts-de-Seine, Val-de-Marne and Seine-Saint-Denis) as well as Marne-la-Vallée. Comprising 37 stations, line 15 will provide several connection points to the existing and future public transport networks (Métro, RER and tramway) of the metropolitan region of Paris.
The consortium of Vinci Construction and Spie Batignolloes won a major contract within this project of the Grand Paris Express. The contract worth € 926 million includes the construction of a tunnel with a length of more than 8 km. It also includes the construction of five new metro stations (Chétillon Montrouge, Bagneux, Arcueil-Cachan, Villejuif Institut Gustave Roussy, Villejuif Louis Aragon). The entire project period is scheduled for 70 months.
