This is a new map.
It has a fair bit of flat terrain for huge desert cities and a deep gorge through the middle.
Note: Most custom bridges wont go across the gorge from the very top, but you can either build a tunnel then a bridge over the water or make a road down the sides of the gorge.
This is also a 2K map.
Bulldoze the trees in the water.
