Interstate Highway System
The Interstate Highway System has been called the Greatest Public Works Project in History. From the day President Dwight D. Eisenhower signed the Federal-Aid Highway Act of 1956, the Interstate Highway System has been a part of our culture as construction projects, as transportation in our daily lives, and as an integral part of the American way of life. Every citizen has been touched by it, if not directly as motorists, then indirectly because every item we buy has been on the Interstate System at some point. President Eisenhower considered it one of the most important achievements of his two terms in office, and historians agree.
