What does the redevelopment of the station involve?

In the station, the project aims to enlarge and reorganize the spaces in order to improve passenger traffic both in the existing spaces of lines A and E but also in the future spaces created with the arrival of Metros 1 and 15. It also aims to provide an urban pedestrian link between the east and west of Val de Fontenay.
