We are also a key player in the construction of the Grand Paris Express, an ambitious programme that is conducted by Société du Grand Paris (SGP) and which is part of the comprehensive Nouveau Grand Paris project. This includes the development and modernisation of the existing network as well as the extension of four metro lines, to bring Paris closer to its surrounding suburbs and to foster greater suburb-to-suburb mobility.
