T3b extension with two variants: to Porte Maillot or Porte Dauphine
In continuity with transport infrastructure first built and operated in 2006 (Pont du Garigliano-Porte d’Ivry) and then extended in 2012 (Porte d’Ivry-Porte de la Chapelle), the tramway T3 continues to advance around Paris with the start-up of service in 2018 of a new section between Porte de la Chapelle and Porte d’Asnières. The T3 affirms its role as a peripheral transport system and an important link in the Île-de-France structural network.

Two variants:

  • One variant ends at Porte Maillot, an extension of about 2 km.
  • Another variant ends at Porte Dauphine, an extension of about 3 km.

The T3b extension to Porte Maillot is part of the Île-de-France Regional Council’s Masterplan (SDRIF), approved by the Regional Council meeting of 18 October 2013.

The new 2015-2020 State-Region planning agreement (CPER) also recognises the interest of this extension, which is incorporated in its multimodal mobility plan.

01. Advantages

The extension will strengthen the public transport grid through connections with the RER C, the western extension of RER E (EOLE), and 2 or 3 metro lines, depending on the variant that is finally selected (M3 and M1 if the tramway ends at Porte Maillot; plus M2 if the tramway is extended as far as Porte Dauphine).

02. Urban integration

The T3 western extension aims to provide efficient public transport services, accessible to all, along the northwest section of the Paris ring road.

The T3 western extension would serve extremely dense population areas and employment basins, which are currently served by the PCI and PC3 inner ring bus lines. This extension would serve the major, strategic sector of Porte Maillot, a prime metropolitan centre that adds to Paris’ international reputation for economic activity and business travel.

The project contributes to the extensive transformation of the Porte Maillot sector, which is currently being redeveloped by the Atelier Parisien d’Urbanisme (APUR) and the City of Paris (extension of the Palais des Congrès; reconfiguration of the loop road). With the Porte Dauphine variant, the T3b would also serve the University of Paris-Dauphine.
