Full Answer

Highway systems are generally supported by federal funding and state governments. These funds provide improvement in the condition of roads and bridges. Tax revenues and tolls are also used to contribute to up-keeping the conditions of highways.

President Dwight D. Eisenhower is often referred to as the "Father of the Interstate System." Although the concept of an interstate highway system was first proposed in a report to Congress in 1939, it wasn't until Eisenhower took office in 1953 that he made the revitalization of national highways a goal for his first term. During his time in the military, Eisenhower had witnessed the efficiency of Germany's Autobahn highway system firsthand, and he believed that the United States needed an equally effective roadway system.
