Do you know how the Interstates in the USA are numbered? Do you see a pattern here?

East West are even numbers and North South odd numbers.

Not only that, but the mile markers start at the west and south points of each state and are highest at the north and east points of each state. Kinda handy to know.

The interstate name numbers represent the approximate percentage of the amount of the country to the west or south of the given highway.

E/W even, N/S odd. Mile markers start from the south and/or the west.

This is from memory, so correct me if I'm wrong. I remember that the interstates were promoted as escape routes from cities in case of nuclear attack. Reality is that half of the people in this country would be dead within minutes of a full-scale launch by Russia, faster than most people could even get to the interstate highways in their cars. Many, if not most of the rest, would have no place to go, and many, if not most of them, would die soon after the attack from the secondary effects. I also seem to remember a documentary describing how General Motors promoted the interstates as a means to increase travel by cars.

The odd/even pattern for N/S and E/W highways was established when the "US Highway" numbering system was developed in the 1920s by agreement among the states (not by Federal action.) The interstates just picked up the same system for direction, but reversed the numbering order - US Highway numbers increase East to West and North to South, while Interstates are the opposite.

I seem to recall reading that the Constitutional excuse for making highways a Federal matter was National Defense - providing a network of roads adequate to move military men and equipment rapidly as needed. I think there is (or at least was) a requirement that there be 2-mile long straight flat sections of interstate at regular intervals that could be used as aircraft runways if needed.

THAT is very interesting.... never considered that. Planned or coincidence ?

Bingo!
Next time you're driving down I-95, and around Fayetteville, NC note the girders under the overpasses.
They have twice or more support than most others. Fort Liberty (aka Ft. Bragg) near by.
Just my observation.

One mile of straight highway out of every five.
