T3b extension to Porte d’Asnières
The new extension of tramway T3, between Porte de la Chapelle and Porte d’Asnières, is a continuation of the first extension between Porte d’Ivry and Porte de la Chapelle, inaugurated in 2012.

The T3’s second western extension, a 4.3 km segment with 8 new stations, crosses the northern part of the 18th and 17th arrondissements of Paris. Like the M14 extension in this same area, this new T3 extension will link the major urban development projects of northern and northwest Paris, and will serve fast-changing neighbourhoods. It will keep pace with the development of the Clichy-Batignolles district, the opening of the future courthouse (Palais de Justice), and the transformation of the nearby communities of Clichy and Saint-Ouen.

The T3 extension to Porte d’Asnières addresses several challenges concerning mobility, urban rezoning and society.

It has the following objectives:

  • Strengthen the links between Paris and neighbouring towns, and facilitate suburb-to-suburb transport
  • Improve transport conditions in the neighbourhoods of northwest Paris
  • Facilitate connections with other public transport lines
  • Encourage the use of public transport
  • Contribute to the rejuvenation of public spaces along the tramway.

Useful information:

  1. Département 75
  2. Connections with the RER C / M4, M12, and M13 / numerous bus lines
  3. Future connections with the M14

01. Advantages

  • Connections with 4 metro lines (M4, M12, M13, and the extended M14), RER C and roughly 20 bus lines.
  • Trams will run every 4 minutes in each direction during peak hours.
  • Facilitate east/west travel.
  • Quieter, more comfortable rolling stock.

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 extension to Porte Dauphine, the T3b will also serve the University of Paris-Dauphine.
