The automatic metro line 1 now connects La Défense (92) to Château de Vincennes (94). The project for its extension to Val de Fontenay provides for 3 new stations: Les Rigollots in Fontenay-sous-Bois on the edge of Vincennes (94), Grands Pêchers in Montreuil (93) and Val de Fontenay (94) with connections to the RER A and E, the future metro lines 15, tram T1 and bus Bords de Marne.
This project is not new, but it has evolved since its last presentation in 2022: discover its evolutions!
