The Federal Interstate Highway System
Explanation:
When Eisenhower became president in 1953, he envisioned the construction of a nationwide interstate highway system that would link the country from coast to coast, and from north to south, connecting the main cities as well.
Eisenhower believed that such a system would greatly increase economic growth, and raise standards of living.
The Interstate Highway System was started in 1956 by the passing of the Federal Highway Act, and was only completed in 1992. It has had a cost of over 500 billion dollars, and has been mostly financed by an excise tax on fuel.
