Extension of the metro lines: after the extension of the 12 in Aubervilliers, who’s next?

The extension of metro line 12 to Mairie-d’Aubervilliers comes into service from this Tuesday, May 31. The next on the list, to cut the ribbon, will be, at the end of 2023, line 11 with its 6 km extension between Mairie-des-Lilas and Rosny-sous-Bois, still in Seine-Saint- Dennis. Modernization work and the development of the six future stations are continuing.
