Another step has been completed, so I can now add to this thread. Please have patience while the images load.

I created roads and bridges atop the terrain map in Adobe Illustrator, using different layers so that I could isolate both and export them separately. I worked in color, but turned the roads and bridges into a black and white alpha when i exported. It’s more useful to combine the roads with the squares and the foundations of the mansions since they have a similar texture.
