It's an urban freeway. Beware the speed limit : 70km/h, 50km/h or 30km/h at the ends. Its official name is "Voie Pierre Mathis".
When everything is all right, it's the easiest and fastest way to go from one end of the city to the other. But when a accident occurs, it becomes a trap from which it is long and difficult to exit, because of the traffic jams and the low number of exits.
