General Colin Powell summarizes the impact and significance of the Interstate Highway System on its 50th anniversary. He discusses how the original visionary for a national road network laid the groundwork over 100 years prior. Eisenhower's experience traveling across the country and seeing Germany's autobahns inspired his pivotal role in establishing the Interstate system in 1956. The system transformed America economically and socially, allowing for new mobility, industries, and connectivity while also serving important national security purposes during Powell's military career.
