A sufficiency rating was made of the State Highway System of Idaho. The following three general categories were selected for evaluation: condition, safety, and service. A rating of 100 is perfect; a rating of 65 is considered tolerable. A rating of less than 65 indicates a highway is likely to be seriously deficient in important respects. The 1973 study covered 4,876.45 miles of State Highways in rural areas and 168.64 miles in cities less than 2,500 population. Of these roads, 1,501.10 miles rated less than 65 and 3,375.35 miles rated 65 and higher. In cities with population 2,500 and over, 177.82 miles of State Highways were rated of which 41.27 miles rated less than 65, and 136.55 miles rated 65 and higher. Tables are presented in this report which show ratings and other data in detail for the State Highways. Through use of these tables, roadway sections requiring attention can be quickly identified. Used in conjunction with other information, construction priorities can be economically and fairly established.
