Improvement of transport in the north-east of Paris
This extension will connect the current terminus, Mairie des Lilas, to the Rosny-Bois-Perrier station, currently served by line E. This extension is part of a broader context of improved transport in the entire north-east of Paris with, in particular, the modernisation of line B, the extension of tram 1 from Bobigny to Val de Fontenay and tram 4 to Clichy-sous-Bois – Montfermeil, tram 3b from Porte de la Chapelle to Porte d'Asnières, and the future metro line 15.
