President Dwight D. Eisenhower helped to create the formation of the interstate highway system and the Federal Aid Highway Act of 1956 authorized its construction.
It took 35 years to create this system, totaling 47,856 miles built – making it the world’s second longest after China’s. This was one of the largest public works projects in American history during that time.
One of the uses of the highway system was for national defense. In case there was a ground invasion on American soil, the U.S. Military would be able to transport troops across the country efficiently.
Additionally, this act helped improve road conditions, such as cracked bridges, potholes, and mud. President Eisenhower traveled across the country in 1919 in the U.S. Army’s Transcontinental Motor Convoy and witnessed the terrible condition America’s roads were in. Also, it took 2 months to travel.
