A major accomplishment of President Eisenhower was the beginning of what?

A major accomplishment of President Eisenhower was the beginning of the Interstate Highway System, which he initiated in 1956 with the Federal-Aid Highway Act. This vast network of highways transformed American transportation by facilitating efficient movement of goods and people across the country, boosting the economy and suburban growth. The project was inspired in part by the need for national defense and was influenced by the German Autobahn system. Eisenhower's vision helped shape modern America's infrastructure and mobility.
