On the Road...

There are enough roads in the U.S. to stretch from the earth to the moon 8 times!

The U.S. interstate system has a total length of over 46,000 miles, but that is only a small fraction of the total number of roads in the country. Transportation engineers have helped to build almost 4 million miles of road in the United States. That's enough to stretch from the earth to the moon 8 times.  And the concrete used to construct the Interstate System alone could build a wall nine feet thick and 50 feet high around the world’s equator.

Brief history of the Lincoln Highway, one of the first in the country.
