June 29, 2020, marks the 50th anniversary of the signing of the Federal Highway Act of 1970 by President Dwight D. Eisenhower. This landmark legislation set the wheels in motion for the development of one of the most significant contributing factors in our nation’s – and our state’s – growth, economy and mobility – the interstate system.To commemorate this milestone, January 1, 2020-January 1, 2021, has been designated the Year of the Interstate. Join the Tennessee Department of Transportation, the American Association of State Highway and Transportation Officials (AASHTO), and other departments of transportation around the nation in celebrating the anniversary of one of our nation’s greatest public works projects.
This commemorative Web site was designed to share information about the history of Tennessee’s interstate building era, offer educational resources to all ages, highlight ongoing national and state celebratory activities, and engage Tennesseans in the celebration.
Explore this site and learn more about how you can become involved in the celebration. Share your own story of involvement in the building – or simply of riding on – the first interstates in Tennessee. Tell us how the development of interstates impacted your life, and feel free to share any photos you have of those first moments of traversing interstate roadways.
Interstates play a critical role in our daily lives – from allowing us to visit loved ones and take quick family vacations to getting life’s essentials rapidly transported from farm and factory to the communities where we live. With your help, we’ll make the Year of the Interstate an educational and memorable milestone in our state’s history.
