Considered the " backbone " of the Grand Paris Express, line 14 was extended to the north and south on June 24, 2024. Orly airport can now be reached from Saint-Denis Pleyel in just 40 minutes.
But the work is far from over for the Société des grands projets, in charge of the design and development of the Grand Paris Express, as 4 new metro lines are expected in the next few years in the Paris region: lines 15, 16, 17 and 18.
As work continues on the 60 or so new stations, Société des grands projets is taking advantage of the European Heritage Days to open the doors of 13 of them to the general public. Join us on Saturday, September 20, 2025, to discover the construction sites of 13 Grand Paris Express stations, including the Arcueil - Cachan station, the Noisy - Champs station and the eagerly-awaited La Courneuve Six-Routes station. On the program? Unique tours of these stations under construction, open from 9:30 a.m. to 5:30 p.m.
Please note that tours of each station are free of charge and require no registration. Tours last between 1h and 1h30, and are guided by Grand Paris Express and construction teams. On-site visits are subject to availability (groups of 20 to 25 people maximum).
