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.
