Within a few years the nation would see construction begin replacing a network of two-lane U.S. highways with the multi-lane, high-speed interstate system we know today.  This system that has become the backbone for America’s prosperity and quality of life. The American Association of State Highway and Transportation Officials has been there every step of the way and in this video AASHTO communications director Lloyd Brown, shows you where you can find out more information about this historic anniversary.
