I would dare to say today, that unpaved roads are in better shape, (as far as holes and bumps), than paved roads across the nation on the average. Paved roads still win the the Dust category. "I do not drink officer. I'm just avoiding all the paved road rot."
The best paved freeways today, are also private turnpike freeways. They may be some of the best roads in the world that are over several decades old that are maintainers by any government. I praise this man for developing the coal industry as a private company. That is about it.
