In the Constitution, Congress is charged with providing for the general welfare of the country’s citizens. Historically, this has meant improving transportation, promoting agriculture and industry, protecting health and the environment and seeking ways to solve social and economic problems.
In 1956, Congress passed the Federal-Aid Highway Act, popularly known as the National Interstate and Defense Highways Act, authorizing federal funding for the extension and construction of a robust network of interstate highways. This project was one of the largest public works in U.S. history establishing key transportation infrastructure that impacted lives of all Americans — changing communities, access and economic possibilities and also providing key routes for evacuating urban centers — a critical national defense issue in the Cold War era.
Analyzing primary source material, students discuss the origins and reasons for the National Interstate and Defense Highways Act. Then, they work with historical and contemporary maps as they consider the impact this important congressionally funded project. While intended for 8th grade students, the lesson can be adapted for other grade levels.

Primary source material:
When introducing maps, consider reviewing some general numbering systems for roadways. For example, interstate highways created in 1956 have a number starting with “I.” Older federal highways start with “US.” State or local roads may have other identifying characteristics. Also, for the most part, odd numbered highways run north-south and even numbered routes run east-west.
