Which person was most responsible for the increased demand for highways

Dwight D. Eisenhower, is the right answer.

Explanation:

On 29 June 1956, Dwight Eisenhower, the then President of the United States, approved the Federal-Aid Highway Act. The act constituted a “National System of Interstate and Defense Highways of 41,000-mile” that would, according to him, reduce hazardous roadways,  traffic jams and incompetent ways, all the other stuff that appeared in the way of “rapid, reliable transcontinental journey.” For such reasons, the act of 1956 stated that the development of an extensive expressway arrangement was “indispensable to the interest of the nation.”
