Overview
There are 70 primary interstate highways in the Dwight D. Eisenhower National System of Interstate and Defense Highways (commonly known as the Interstate Highway System, or IHS) is a network of freeways in the United States. The oldest parts of the interstate system date back to the 1950s, and the planning for the system began prior to World War II.
