line 18 accelerates on the Saclay plateau

The regional council of Ile-de-France, the state (the Paris-Saclay public development agency, the Société du Grand Paris, which builds the super-metro, the Paris Ile-de-France prefecture) and the urban agglomeration community. Paris-Saclay will sign, on February 14, 2019, an agreement to release the land required for the line 18 of the Grand Paris Express between Orly airport and the CEA Saint-Aubin. The second part between CEA Saint-Aubin and Versailles-Chantier is still planned for 2030.

"We have fought on the subject in the last few months," underlines with The gallery Michel Bournat, Mayor (LR) of Gif-sur-Yvette and President of the agglomeration Paris-Saclay.

"After the rumors about the abandonment of the line 18, the situation is clarified and confirmed.It is a strong signal sent to the academic world, the economic world and the political world."

"A triggering event for the arrival of companies"

In concrete terms, the three types of land concerned are the locations of the stations of tomorrow, the future maintenance site located at Palaiseau, as well as the plots below the viaduct for the aerial part. "In the majority of cases, it will be a transfer for free.There are still financial negotiations on ZACs were planned facilities," explains the mayor (UDI) of Igny and vice-president of Paris-Saclay responsible for mobility and transport Francisque Vigouroux.

Originally planned for 2024 and then for 2027 after the cancellation of the 2025 World Expo, this portion of line 18 is expected to arrive in the second half of 2026. "I want to believe it", says Jean-François Vigier, after the arrival of three Presidents of the Republic on the site in a few years. The mayor (UDI) of Bures-sur-Yvette and vice-president for economic development of the agglomeration hopes that "It's going to be a trigger for the arrival of companies, many have been cooled by the three-year lag."

Alternatives while waiting for the Grand Paris Express

While waiting for delivery of the Grand Paris Express, all modes of transport, individual or collective, are already saturated in this area straddling the Essonne and Yvelines. The mayor (LR) of Palaiseau and special delegate of the region responsible for new mobility, Grégoire de Lasteyrie, announced yesterday the strengthening of bus lines to access and leave the plateau. Paris-Saclay is also a candidate for a call for projects of Ademe on autonomous vehicles with Transdev, Renault and Nokia, but without waiting for the results, will experiment this solution next spring. The community of agglo is also working on a data aggregator of twenty private and public mobility actors to build an algorithm that would recommend one or more types of transport according to the schedule and route. The device should be presented within two to three months.

In October 2017, Emmanuel Macron also expressed the wish to see the university and scientific hub evolve "towards a MIT à la française". His dream : "to hatch a unicorn in a few years". The head of state had nevertheless rejected "any attempts at standardization doomed to failure" noting the existence of two complementary poles to "transversal elements ". On the one hand, the intensive research university "Université Paris-Saclay", concentrated in Orsay and Gif-sur-Yvette, which will bring together the universities of Paris-Sud, Versailles-Saint-Quentin, Évry, Central Supélec, ENS Paris -Saclay and the IOGS (Institute of Optics Graduate School); and on the other hand, an alliance of grandes écoles with the X, ENSTA, ENSAE, Telecom Paris Tech and Telecom Sud Paris.
