What is the cost of the project and how is it financed?

The cost of extending the T10 tram into a tunnel is estimated at €730 million, including €110 million for land and €30 million for rolling stock. At this stage of the studies, it is an estimate at the feasibility stage of more or less 20%, which will have to be refined and which may evolve according to the development choices that will be made in the context of subsequent studies.
