What are the stages of the project?

Following preliminary studies carried out by Île-de-France Mobilités (then STIF) and RATP, the project was submitted to public consultation. It was held from 10 November 2014 to 10 January 2015 and nearly 3,000 opinions were collected. The results of the consultation were approved by the Île-de-France Mobilités Council on 8 July 2015, taking into account the lessons learned from the consultation.
Subsequently, Île-de-France Mobilités and RATP undertook in-depth studies on the choice of intermediate station between Grands Pêchers and Verdun.
At the monitoring committee meeting of 19 October 2016 bringing together the partners and elected officials concerned, the project owners presented the conclusions of these studies and selected the route through Grands Pêchers in agreement with all the partners.
The studies of the schematic of principle have continued on the basis of this single route, also making it possible to compile the file of the investigation prior to the declaration of public utility which is being held from January 31 to March 2, 2022.
The next steps of the project, if it is declared to be in the public interest and subject to obtaining the necessary funding, include the completion of the detailed technical studies for the preliminary design (AVP) and the project (PRO).
