Good to know: Significant construction works for this extension
The extension of T3b to Porte Dauphine required significant urban restructuring, with two simultaneous construction projects:

- Structural reinforcement above the RER C, using a new bridging slab, to ensure that the RER galleries can support the future weight of the tramway.
