Eventually to cost nearly $90 billion, the Interstate Highway System will connect all U.S. cities of 50,000 and larger, eventually carry 25% of all highway traffic. The article traces the explosive growth of U.S motor vehicle ownership—8,000 in 1900 and 110 million today. Traffic congestion grew to awful levels. Motor vehicle deaths approached 60,000 a year, and 50% of all accidental deaths. The German autobahns and the Pennsylvania and other turnpikes showed there was a new breed of highway that could help. Too, a massive highway program would spark the economy. Started in 1956, the Interstate system today is about 80% complete, with the motor vehicle a major driving force in sparking the world's mightiest economy. Economic and social impacts are reviewed. First of a series.
