YuperTIL in Wytheville, VA, I77 and I81 cross so that when traveling on I77N, you are also on I81S but traveling West
Same with I-81 and I-64 between Staunton and Lexington. :)
Oh, I thought you meant that the two interstates overlapped. Not that one is south when the other is north both going in the same direction. That’s neat!
Here I am a lifetime Virginian, with uncountable trips through Wytheville, and never realized this.
Where I live, US 285 North goes East and crosses CO 470 East, that goes South.
I was just thinking about that silly interchange when I read that title!
Jinx!
In Berkeley, Ca you can be on 80 E, 580 W, and be driving North.
