US interstates: facts about 50 years of road construction

America's Interstate Highway System has been called an economic and democratizing force that's the envy of many other countries. The system, which is celebrating its 50th anniversary, bears the name of President Dwight D. Eisenhower, who signed the Federal Highway Act of 1956 that got the ball – and the earthmovers – rolling. In 1994, the American Society of Civil Engineers classified it as one of the Seven Wonders of the United States, along with such landmarks as the Golden Gate Bridge and Hoover Dam.
