If you've driven on an interstate highway, you can thank the New York World's Fair of 1939.

The theme of the 39 Fair was the world of tomorrow,

and millions of people came to pay 75 cents to take a look. One of the most popular attractions at the World's Fair was part of the

General Motors exhibit called Futurama. Sensational is the Futurama that projects you into 1960, the Highways and Horizon show.

Each day people waited for hours to see the Futurama exhibit.

They wanted to sit and plush traveling sound chairs.

These moved you around a conveyor belt called the carry-around.

This 18-minute ride led you around the nearly one-acre model

of what cities were going to look like 20 years in the future.

This would have been 1960 to the people who came.

And what did those cities of the future look like?

A quarter of a mile high, skyscrapers tower,

with convenient rest and recreational

facilities for all. On many of the buildings are landing decks for

helicopters and auto gyros.

They were going to be filled with sleek skyscrapers,

streamlined cars, and highways, and highways.

They were supposed to connect the whole country, and these highways were beautiful.

Enormous cloverleaf interchanges, elevated ramps, triple-decker lanes,

and this Futur exhibit was one of the first times

at the American public, and remember they were still recovering from the Depression,

was introduced to the idea of enormous multi-lane highways that were going to crisscross the nation.
