“Les navettes de l’agglo” is a service of free shuttle buses in several cities of Paris-Saclay. It completes the stops list served by commun buses.
In the context of this scheme, 3 lines have been installed at Gif-sur-Yvette (lines M, N and O). To facilitate the travels of the inhabitants of the quartier de Moulon, the M line is now passing each Sunday morning (market day). It links the Mail Pierre Potier to the market, by way of rue Joliot-Curie.
For the lines N and O, they are allowing you to move around Gif-sur-Yvette and Bures-sur-Yvette the Wednesday and are accessible by bus (line 11).
Those shuttles can accommodate 20 people maximum and are wheelchair accessible.
