The consultation file and its summary are online

The consultation file for the Metro 1 extension project to Val de Fontenay is available online, along with its summary.

A complete file to prepare for the consultation

Drawn up by the project owners (Île-de-France Mobilités and RATP), this file presents the project as a whole: developments since 2022, diagnosis, situation in the absence of a project, alternatives, integration variants, effects on the environment, cost and schedule. A shorter summary offers a quick read, for a first acquaintance before going further into detail. These documents also present all the information and participation procedures planned with the guarantors of the National Commission for Public Debate.

Useful reading before the opening of the exchanges

These documents are available now, before the start of the preliminary consultation, which will be held from October 5 to December 11, 2026. They allow you to prepare your participation in the public meetings, thematic workshops and local meetings offered during this period.
