what do you mean by this? nearly any road that isn't just one lane will have lines
When its clear someone lives in a city not a town.
I've done a few roads for smaller towns/neighborhoods, and one of my favorites was a very gentle hill (like 1f per 16studs, I think) and it gently wound back and forth - but not at a specific interval, like there could be a sharp turn followed by two very gentle turns, some turns may not turn as far, ect. What I personally loved about the road was the sidewalk was a little bit away from the road, like 6-8 studs, and grass that dipped to make like a small trough was in between, and it didn't make a clean line along the street, so if you looked at the road when it was going straight, the grass would look staggered along the edge - it'd come in 3 studs, then 2 studs, then 1, then 2, then 2, then 1, then 2, then 3, then 3, then 2...
Anyways, I like where you're going with these roads, if you're going for the dreaded grid. I'd really suggest to stop worrying about making road
[pieces and just make the road itself. Maybe set up your town/neighborhoods size, and just start making roads.
Just my thoughts.
