Federal Highway Act of 1956June 29, 2006, marked the 50th anniversary of the signing of the Federal Highway Act of 1956 by President Dwight D. Eisenhower. This landmark legislation provided initial funding for construction of the National System of Interstate and Defense Highways.
Too often taken for granted, the Interstate Highway System is responsible for dramatically improving our mobility, highway safety, quality of life, and commerce.
This Web site represents a compilation of countless resources about the building of the interstate system, with an emphasis on Iowa's role in that historic era. Read stories from individuals who helped construct the system, glance through the photo gallery, learn about the invention of the world-famous slipform paving machine or explore the Iowa interstate completion map to find out when the route nearest your community was finished.
You'll also discover highlights from the 50th anniversary celebration, including stops by the American Association of State Highway and Transportation Officials' national motor convoy at Living History Farms in Urbandale and the I-80 Truckers Hall of Fame Museum in Walcott. Also featured are photos from the very popular Iowa pictorial postmark cancellation event held June 29.
Have a great time exploring this site and learning a little bit more about Iowa's transportation history.
