Wellsville Canyon – Bad Roads for RVs is on U.S. Highway 89/ U.S. Highway 91, two miles north Dry Lake. It is steep and should be avoided in the winter. This is part of the descent from Sardine Summit.
Of course, you could say that RVs should avoid traveling in the winter in the Rocky Mountains and I would agree. It goes double for steep roads in the winter.
The beginning of the descent starts as the road turns east into Wellsville Canyon between Cart Hill and Murrys Hill and ends in the town of Mount Sterling.
In the summer, U.S. Highway 89/ U.S. Highway 91 is merely a steep road but I think you should know what you are getting into before you go there. Really the road is very a nice four-lane divided highway and overall the grade alone isn’t a good enough reason to not travel on U.S. Highway 89/ U.S. Highway 91 in Wellsville Canyon.
In the winter expect snow and ice. The road is maintained well but melting snow will run across the road and turn to ice nightly making for very hazardous driving.
Expect large vehicles to be traveling at very slow speeds relative to traffic or speed limits.
