The extension serves the 17th and 18th arrondissements and is forecast to bring an additional 90,000 passengers per day on to Line T3b. The extension adds eight stations to the line, including interchanges with metro lines 4, 12, 13 and 14, RER Line C and more than 20 bus routes.

The €211m cost of infrastructure was financed by the City of Paris (60%), the region of Ile-de-France (28%), and the French government (12%).

In addition, Ile de France Mobility provided €48m for the acquisition of 14 additional Alstom Citadis 402 low-floor LRVs, expanding the Line T3 fleet to 63 vehicles.

The completion of the extension takes the total length of Line T3 to 26.2km with 51 stations serving eight arrondissements.

The initial phase from Pont du Garigliano and Porte d'Ivry opened in December 2006 and today Line T3 is Paris’ busiest tram line, carrying around 500,000 passengers on weekdays.

Studies are underway for the next phase of the project, which will extend Line T3b from Porte d’Asnières to Porte Dauphine. The 3.2km extension will serve seven stations, including interchanges with metro lines 1,2, and 3, and RER lines C and E.

The €165m project will be financed by the French state, the city of Paris and the region of Ile-de-France.
