BorisS1990, that is awesome pictures. That's kind of inspiration I need! I love how you planned it out a bit and then laid it out. Sometimes I just can't lay it out the way I want to. I guess that's why you kept playing with the intersection until you had it flow right.
I remember an old article on how to use the different roads to make the maps flow as well. Obviously, main highways gets you from city to city and then you have your access roads and main roads. Something like that. I think I'm looking to get something like that and then going from there. I'll be playing around later today and maybe I'll take some pictures to share!
