About Société des grands projets

We are developing new everyday mobility solutions. Large-scale decarbonized transport projects serving territories and residents. Since 2010, we have been managing the development of the Grand Paris Express, whose four new metro lines (15, 16, 17, and 18) and the extensions of line 14 will revolutionize suburban travel. Nationally, working closely with local authorities, we support them in successfully carrying out metropolitan regional express service projects.
