By connecting with tramway T2, the T1 extension project aims to facilitate peripheral travel in the Hauts-de-Seine département. It will reinforce the area’s public transport grid.

The project’s main objectives are to improve access to employment basins and local facilities, and to enhance mobility flows between communes.
