Even a well-engineered road system is bound to disturb some aspect of the native biota and wildlife. In order to determine what roads are necessary to the public, a cost-benefit analysis should be done. If the costs are outweighed by the benefits the road should be built. Many benefits can occur with the construction of a new road, or rehabilitation of an old one. One is commodity-related benefits.
Roads are a necessary means of transport for goods such as timber, cattle and minerals.
If roads are closed, a domino effect may be felt in the economy. For example, one study determined that reducing road densities would lead to greater reliance on helicopter logging systems, which would increase logging costs by about 2.5 times. This cost increase would lead to a decrease in current timber sales, which leads to an economic downturn. People pay taxes in order to use their National Forests. If a lot of roads are closed, the public will be disgruntled to see that an increase in taxes over the years has led to a decrease in service by our National Parks.
