The flagship project of the Grand Paris Express consists of building 200 km of automatic metro by 2030 to link the territories of the Greater Paris area.

A titanic project, the Grand Paris Express network

Four new metro lines around the capital will be created (15, 16, 17, 18) and line 14 is to be extended to the south and north to link Saint-Denis to Orly airport. The Grand Paris Express is a major project that is at once social (opening up cities), urban (accompanying and driving numerous development operations around the stations), environmental (alternative to the car) and economic (approximately 115,000 jobs created).

It is managed by the Société du Grand Paris, an institution created in 2010, whose mission is to design and build the new metro. Work on the first lines began in 2015. The lines will be brought into service progressively until 2030.

Focus on line 15 West

By decree of the Council of State of 21 November 2016 (decree n°2016-1566), line 15 West was declared to be in the public interest. Line 15 West will link 11 stations from Saint-Denis Pleyel to Pont de Sèvres in 25 minutes. Two departments are affected by line 15 West: Seine-Saint-Denis and Hauts-de-Seine. This strategic line, 22.4 km long and underground, will provide better links between the regions and benefit more than 800,000 inhabitants! It will also help strengthen the economic hub of western Paris. La Défense and its 4th largest business district in the world is concerned, with a more direct link to the other strategic areas of Greater Paris (such as Saint-Denis Pleyel or the airports of Roissy and Le Bourget). Delivery of line 15 West is scheduled for 2030.

Benefits for passengers

  • By 2030, line 15 West will offer optimised connections with the Transilien L and U lines, metro 1, RER A and E lines, tramways and surrounding bus lines.
  • La Défense will be 13 minutes from Saint-Denis Pleyel (compared with 26 minutes today)!

The 15 West line in a few figures

  • 14 municipalities involved, including 2 départements
  • 11 stations, 10 of which will connect with the metro, RER, transilien or tramway
  • 22.4 km of automatic underground metro
  • 5.39 billion of investment
  • 2030, when the line will be in service

A new station at Puteaux

The location of the La Défense station raised many questions related to technical and financial constraints. It was therefore the subject of a public enquiry on the declaration of public utility in June 2021. The conclusions of the enquiry are available on the Société du Grand Paris website.

The "La Défense" station will finally be located in Puteaux, on Avenue du Général de Gaulle, in the new Rose de Cherbourg district. Preparatory work began in January 2023. Led by Orange, it will last until August 2023. They consist of taking soundings and moving existing networks (drinking water pipes and telecommunications networks). This is an essential step to free up the space for the future station! Once the right-of-way has been freed up, another important stage is planned: digging and building the underground part of the station.

La Défense station construction schedule

2023 to 2025: preparatory work July 2023: civil engineering notification Horizon 2030: delivery of the station

For information: a consultation phase for the construction of the stations, tunnels and service structures is underway. The designer and builder will be selected by the Société du Grand Paris in 2023. Following this, a more complete work schedule may be communicated by the Société du Grand Paris.
