# Stuff You Should Know - US Interstate Highway System

Josh and Chuck dive into the fascinating history of America's massive interstate highway system, exploring how a network of over 48,000 miles of super-engineered roads came to exist and completely transformed the country. They trace the journey from early 20th-century dirt roads and the Good Roads Movement through FDR's vision and Eisenhower's decisive push to finally build these defense highways in 1956, uncovering the military strategy, economic stimulus, and PR campaigns that made it all happen. Along the way, you'll learn about colorful characters like Carl Fisher and the Lincoln Highway, why there's no Interstate 50, and the surprising amount of research and testing that went into making these roads both safe and standardized.
