Once Upon a Time in America (6.29.09)
On this day in United States history in 1956, President Dwight D Eisenhower signs the Federal-Aid Highway Act, making it law.
This act essentially created the U.S. Interstate Highway System.
Up to that point, it was the largest public works project in our nation’s history.
Eisenhower mostly supported it because he felt that if our country was ever invaded, the military would need to be able to transport troops and equipment quickly throughout the country.
Here is some Interstate Highway Quick Facts for you:
The Interstate System measures 46,876 miles (as of 2006).
They are funded partially by the federal government but owned, built, operated and maintained by the states or toll authorities.
From 1974 to 1987 the maximum speed limits on an interstate was 55 mph but currently ranges from 65 to 75 mph depending on the state. In fact, part of I-10, I-20 (western Texas) and I-15 (central Utah) have speed limits of up to 80 mph.
The highest traveled interstate (volume-wise) is I-405 in Los Angeles, California.
The longest interstate is I-90 which runs for over 3000 miles from Seattle, WA to Boston, MA.
