US Interstate Highway Myths - But Are Great To Believe Anyway...

GARAGISTRY'S VERSION OF LEGENDS & LIES...
At one time or another, most everyone believes urban legends to be true, whether there is proof or not. While reviewing information concerning this weekend's 60th Birthday Celebration of the US Highway System, we found some interesting "facts" that, unfortunately, are not so...  But they live on, and doing our patriotic duty this weekend, we're pleased to provide you "the truth" about many of the Interstate Legends...

Myth 1.  President Eisenhower conceived the Interstate System.
Fact:  The Interstate System was first described in a Bureau of Public Roads report to Congress, Toll Roads and Free Roads, in 1939. It was authorized for designation by the Federal-Aid Highway Act of 1944, with the initial designations in 1947 and completed in 1955 under the 40,000-mile limitation imposed by the 1944 Act. President Eisenhower didn’t conceive the Interstate System, but his support led to enactment of the Federal-Aid Highway Act of 1956, which established the program for funding and building it.

Myth 2.  President Eisenhower supported the Interstate System because he wanted a way of evacuating cities if the United States was attacked by an atomic bomb.

Fact:  President Eisenhower’s support was based largely on civilian needs - support for economic development, improved highway safety, and congestion relief, as well as reduction of motor vehicle-related lawsuits. Based on what he witnessed in Germany with their Autobahn System during WWII, he understood the military value of the Interstate System, as well as its use in evacuations, but they were only part of the reason for his support.

Myth 3.  Defense was the primary reason for the Interstate System.

Fact:  The primary justifications for the Interstate System were civilian in nature. In the midst of the Cold War, the Department of Defense supported the Interstate System and Congress added the words “and Defense” to its official name in 1956 (“National System of Interstate and Defense Highways”). However, the program was so popular for its civilian benefits that the legislation would have passed even if defense had not been a factor.

Myth 4.  The Interstate System was launched by the Interstate Defense Highway Act of 1956.

Fact:  No such legislation passed in 1956 or any other year. Nevertheless, this title appears widely throughout the media instead of the correct title: The Federal-Aid Highway Act of 1956.


Myth 5.  One in five miles of the Interstate System is straight so airplanes can land in emergencies. (G: Our Favorite Myth...)
Fact: This myth is widespread on the Internet and in reference sources, but has no basis in law, regulation, design manual - or fact. Airplanes occasionally land on Interstates when no alternative is available in an emergency, not because the Interstates are designed for that purpose.
{However, many miles of the Autobahn in Europe are designed to be tactical runways and have been used for military takeoffs and landings during training exercises for years.}

Myth 6.  Interstates are intended to serve only traffic going from State to State.

Fact:  The Interstate System serves interstate, regional, and intra-State traffic, and was always expected to do so. In fact, many routes, including beltways and spurs, are located entirely in one State and serve primarily intra-State traffic.  

Myth 7.  Beltways are designed to carry Interstate traffic around cities.

Fact:  Beltways do help traffic avoid cities, but also are intended to serve metropolitan traffic moving from main highway to main highway.





Myth 8.  Congress should have put the money into mass-transit instead of the Interstate System.
Fact:  This was not an option in 1955 and 1956 when the congressional debate took place.  At the time, transit was provided mainly by private companies. No one in the industry, in State and local governments, or in Congress imagined that the Federal Government would support these companies financially. In fact, the only thing the American Transit Association asked Congress to do was exempt buses from the gas tax.  Congress did so.

Myth 9.  Interstate numbers must be consistent with the numbering plan.

Fact:  The numbering plan is helpful in choosing numbers for added routes. However, in an irregularly shaped country, consistency is not possible. The numbers are consistent for the most part, but irregularities have occurred for a number of reasons, such as addition of a route where a consistent number is not available or withdrawal of a route without concurrent renumbering of routes linked to it. These inconsistencies have no effect on motorists who “navigate” based on maps, new GPS technology, personal knowledge or directions, and other means, not the numbering plan.

Myth 10.  The only man-built object astronauts can see from space is the Interstate System.

Fact:  From an altitude of about 155 miles (250 kilometers), under the best of conditions, the unaided eye of an astronaut can see many built objects on Earth if he or she knows where to look. The Interstate System is not visible as a network, but astronauts using binoculars can see roads, cities, dams, airports, and other objects.

We'll keep looking for more "myths".... and if you know of one, please share it with us.
