Devilspine Canyon is a map with many elevation challenges but also a few areas for a rather large sprawl. It has beautiful vistas, waterfalls, creek beds, towering bridges, lush forest land, tons of resources, long winding freeways and rail, all built with painstaking detail.

For those new to the game. There are several areas that have highway off ramps acting as roads. These are just placeholders to show where the roads can go. You can choose to upgrade them where they are to any other type of road or just bulldoze and make your own.
