New vs. Old

Sometimes, existing roads can be used. Construction of new roads may be more costly and damaging than upgrading existing roads. Any roads already present should be evaluated to determine if they are properly located for long-term needs, have adequate drainage, are suited for the expected use and meet maintenance requirements. Many times, existing roads are in inappropriate locations. Roads may closely parallel streams, have little or no vegetation between the road bank and a stream or go straight up a draw or gully. Roads in these locations probably should be relocated. Other considerations are grade, curves or switchbacks and safety concerns such as blind corners.

Permanent roads can be seasonal or all-season. Seasonal are usually not surfaced, are more narrow and are used when the surface is solid or frozen. All-season roads are usually designed for year-round use but may have some restrictions.
