Interstates, IIRC, are designed so that every fifth mile is a straight line without any curves, so that a plane could land on the highway in an emergency—or if air bases/airports were all nuked in a future atomic holocaust.

You are correct.

I never knew that. That's a fascinating piece of trivia.

Illinois has a LOT of interstate highway (I-24, I-39, I-55, I-57, I-64, I-70, I-72, I-74, I-80, I-88, I-90, I-94, I-155, I-255, I-270, I-280, I-290, I-294, I-355, and I-474.

I’ve think I’ve trucked on every mile of it, except the Chicago Skyway.

Probably 75% of those miles are straight enough, wide enough, and flat enough for regional jets or smaller.
