The T10 tram project was launched in 2016 by Île-de-France Mobilités, the public transport authority for the city of Paris and the surrounding départements, with the support of the French government, the Île-de-France region and the Hauts-de-Seine département. The aim was first and foremost to provide the 175,000 residents and 65,000 employees of the four municipalities served with a fast, reliable and universally accessible alternative to the car. The T10 tramway operates 7 days a week, from 5.30am to 0.30am, with a train every 6 minutes at peak times. It is also connected to other lines in the Greater Paris public transport network (RER, tramway, bus). As with most infrastructure of this type, the development of the new line has been combined with a major upgrade of public spaces, including the renovation of roadways, the planting and widening of pavements and the creation of cycle routes.

Artelia provided support to the project owner, from project design through to the commissioning of the infrastructure, for the various components of the development: urban integration, transport system, rehabilitation and rerouting of networks, modification and creation of engineering structures, organisation, steering and coordination, supervision of tests, communication support, sustainable development management, etc.). A special effort has been made to ensure the sustainability of the project, with safe and clean stations, the creation of planted platforms along the entire route and the planting of around 1,000 trees.
