the extension most likely to be realized is along the rer c route (most likely under the "rue du chevaleret" towards the 13th arrondissement, a neighborhood still poorly serviced despite the opening of line 14 to the station "olympiades" and in consideration of the construction of a university in the paris rive gauche neighborhood). in 2007, the "conseil de paris" deliberated on the importance of expanding line 10 to "ivry-sur-seine". the sdrif adopted in 2008 does not include this proposal, however it does state that "optimization studies of service to seine-amont suggest that changes and/or expansions to lines 7, 10, and 14 may be necessary."
