CONSTRUCTION NEEDS AFTER 1964

There is no foreseeable period in the future when there will be no highway needs. Population growth and other factors in the expanding economy of the United States give every indication that highway travel will continue to increase in the years beyond 1964. Admittedly any attempt to gage with exactness the trend of such future travel, and its attendant highway needs, involves certain hazards. But the alternative of ignoring these future needs is even more hazardous. Sound and defensible long-range highway planning must be based on the best current estimates that can be made of future conditions.
