The T9 tramway line and its 19 stations spread on 10.3 km along a metropolitan axis and join 6 different municipalities in southern Paris : Paris, Ivry-sur-Seine, Vitry-sur-Seine, Thiais, Choisy-le-Roi and Orly.

Lighting design scheme for public spaces following the route aims to develop an inclusive nightscape concept in order to support mobility respecting nighttime urban landscape.

The goal of that project is to create gathering atmospheres for a rediscovery of the public spaces and a new way of living by night through game, interactions and joy.

The place located below A86 highway bridge in Choisy-le-Roi offers a lighting scenography using red and warm yellows hues in reference to bricks walls which are identical features in suburbs houses.
