When the Eisenhower Interstate Highway System was built, it was specified that one mile in every five must be absolutely straight. Why ?

The myth is so the interstate could be used as a runway for planes. There's plenty of places along interstates where the 1 in 5 is not true.

One interstate equipment is time-commemorated via fact the Eisenhower Interstate highway equipment (or extra wisely,The Dwight D. Eisenhower national equipment of Interstate and protection Highways.) it rather is a equipment interior the better national highway equipment.

So, in cases of national emergency, those straight parts can be used as aircraft runways.
