If … Aside from their value as a scenic and often historic resource, unpaved roads have the advantage of lower construction costs than paved roads, require less equipment and skilled operators, and generate lower speeds than their paved counterparts. Yet, like paved roadways, dirt and gravel roads require regular maintenance to keep them passable
