Long Highway map mod?

So I've been looking for a map with a long highway, and small intersections, similar to Dallas. I don't want like huge buildings and generally just want a map like Dallas or Los Angeles without the big city. If you play Roblox, There's a game called Southwest Florida and I like the map, I just want the highway to be longer. In short, I want you, the community, to help me find a map with a long highway, large sized streets, and large neighborhood where you can rip through the streets.

 

The St petersburg highway is a good highway. Or the 50k autobahn loop.
