A new public consultation on the project to extend Metro Line 1 to Val de Fontenay will take place from October 5 to December 11, 2026, offering citizens the opportunity to get informed and share their views.

The City of Montreuil is launching a new phase of public dialogue regarding the extension project of Metro Line 1. This prior consultation, which will run from October 5 to December 11, 2026, aims to inform the public about the developments and challenges of this major project.
The project involves extending Line 1 from its current terminus at the Château de Vincennes to Val de Fontenay, covering approximately 5 kilometers. Three new stations are planned: Les Rigollots, Grands Pêchers, and Val de Fontenay.
This participatory process is crucial as the project can still evolve. It will address the feasibility of the extension, its characteristics, its environmental and socio-economic impacts, and the various alternatives studied. The contributions gathered will help inform future decisions regarding the continuation and deepening of the studies.
Several participation methods are offered during the consultation period. Citizens can attend public meetings, participate in thematic workshops, meet the project teams during local outreach events in the concerned municipalities, or submit their contributions online via a dedicated form or by mail.
A comprehensive consultation dossier and the project's website are available to provide all information regarding the route, ongoing studies, and updates on the extension.
