Who championed the formation of the interstate highway system in the United States?

The formation of the interstate highway system in the United States was championed by Dwight D. Eisenhower. His advocacy for a nationwide system of interconnected highways was largely influenced by his experiences during World War II, particularly the efficiency of the military transport routes. Eisenhower recognized the need for a robust infrastructure to facilitate both military and civilian transportation.

Under his presidency, the Federal-Aid Highway Act of 1956 was signed into law, which provided the necessary federal funding to construct this vast network of highways. This effort not only improved national defense capabilities but also spurred economic growth by enhancing the movement of goods and people. The interstate system has since become a critical component of America’s transportation infrastructure, influencing land use and urban development across the country.
