The Eisenhower Interstate System is a network of highways in the United States, established in 1956. It was created to improve transportation and enhance national defense by allowing for the rapid movement of military troops and equipment. The system spans over 47,000 miles and connects major cities across the country. Named after President Dwight D. Eisenhower, the system was inspired by his experiences with the German autobahn during World War II. The interstate highways are designed for high-speed travel, featuring multiple lanes and limited access points, which help reduce traffic congestion and improve safety for drivers.
