The fact that this road was built in the previous century makes it part of that second category.
In general, we seem unwilling to invest in American road infrastructure. I'd be willing to bet that potholes, the unexciting normal kind you don't even notice in a car, cause more loss of life and loss of money than any particular dramatic road.
At least where I live potholes are the natural result of freeze-thaws cycles.
Smart person, I would never travel on that road even if the long way is 8 hours longer. And driving in winter ? You have to be crazy.
