Streets how do you make em?

[Herc Driver]

I found it easy to use the large styrene signs like the "Garage Sale" or "For Sale" kinds you find at most home supply stores. For a small price you get a good sturdy sheet of styrene that cuts easily and accepts spray paint well. I used them for my roads around my layout with good results. I normally just spray them with a basic grey primer color and add weathering using chalks. Placing some tape under the roadway gives slight bumps and grade changes to the roads.
