Close

The portion north of Chénéville in Papineau RCM is still unmarked on some maps, but it is signed on the road, and is very sinuous. On most of the Chénéville-Duhamel part, it is impossible to reach the 90 km/h speed. In fact it is most of the time a 50–70 km/h speed limit road. It is frequented by campers who go to the Lac Simon recreational center during the summer.
