2.2.Eisenhower Interstate Highway System:

In 1956, Congress passed the Federal-Aid Highway Act of 1956, also known as the National Interstate and Defense Highway Act which created a funding mechanism for the Dwight D. Eisenhower Interstate Highway System (Interstate System) and in September, 1956, Kansas became the first state in the nation to start construction of an Interstate Highway. Approximately fifty-thousand (50,000) miles of the Interstate System have since been completed and the Interstate System continues to be the largest public works project in history. Designed to be bi-directional for normal use, the Interstate System is capable of one-directional flow in the event of mass evacuation or military necessity. While the Federal Government owns some of the ground underlying the Interstate System, states and local municipalities own the vast majority through funding received from Federal grants. Interstate System speed limits range from fifty-five (55) to eighty (80) mph.
