Which person was most responsible for the increased demand for highways?

The person most responsible for the increased demand for highways in the United States was President Dwight D. Eisenhower. His advocacy for the Federal-Aid Highway Act of 1956 led to the creation of the Interstate Highway System, which aimed to improve national defense and facilitate interstate commerce. Eisenhower's vision for a vast network of highways transformed transportation, making it more accessible and efficient for both people and goods. This initiative significantly contributed to the growth of suburban areas and the automobile culture in America.
