What is the timeline for the project?

• 2013: The consultation was a privileged time for information and dialogue between public stakeholders and all the people concerned in the territory, so that they could give their opinions on this project.
• 2014-2015: Following the consultation and its assessment, the studies continued taking into account its teachings.
• 2016: The purpose of the public inquiry was to inform the public and allow them to express their views and assert their interests regarding the public utility of the project, the compatibility of the local urban development plans (PLU) of Choisy-le-Roi and Vitry-sur-Seine, and the possible impacts on the environment. Following this investigation, the T Zen 5 bus project was declared to be of public utility.
• 2018/2019: Preliminary Design Studies (AVP) for the line; Sketch studies (ESQ) and preliminary design studies (APS) for the bus depot.

Next steps:

• Public environmental inquiry (with a view to obtaining environmental authorisation);
