Towards a new Grand Paris metro line for Val-d'Oise

"It's a new project that has been submitted by Val-d'Oise, a department that has been orphaned by the Grand Paris Express", the metro currently under construction around the capital, explained Ms. Pécresse to journalists on the sidelines. the presentation of renovated metro trains for line 6.

This "line 19", proposed "by 2040", would connect Nanterre, Argenteuil and Saint-Denis, which "would really make it possible to completely mesh the network, and make a loop in the Val-d'Oise department, which is missing today" especially since it "has a very strong economic dynamic", according to her.

Line 19 would connect in Nanterre with lines 15 and 18 and in Saint-Denis with lines 15, 16 and 17 of the Grand Paris Express, currently under construction or planned.

The draft master plan for the Ile-de-France region (SDRIF) presented Monday by Ms. Pécresse adds a long branch to this future line 19, which would connect Argenteuil to the prefecture of Val-d'Oise, Cergy.

The SDRIF "really wants to develop polycentralities", with "support points in each department", like Argenteuil whose service is "a very, very good idea", noted Ms. Pécresse.

Funding will have to be found to "complete the Grand Paris Express scheme", recognized the elected official (LR), also president of Ile-de-France Mobilités, the regional transport authority.

The master plan for the Ile-de-France region provides long-term planning for the territory and must be respected by local elected officials in their urban plans. The document, which should replace a previous version adopted in 2013, proposes to project in 2040.

It retains in particular, concerning the Grand Paris Express, extensions of line 14 from Orly to Morangis and line 18 from Versailles to Nanterre, as well as from Orly to Montgeron.

Added to the more or less long-term extensions of lines 1, 2, 3, 4, 7, perhaps 9, 10, 11 and 12 of the metro, the completion of the northern transversal (T11), as well as the creation of an "S line" of suburban trains to save time compared to the RER D between Paris, Juvisy and Malesherbes.
