I got Texas for American Truck Sim, and its mostly the interstates with some highways, but what was really wacky was that every interstate seems to have a side road and all the exits are just on offs to these side roads that run paralell the whole way and lots of bridges.

I am probably not even describing it in a productive way. I just know it is weird next to every other interstate I have seen in the game, and been on IRL.
