Changes

When drawing roads, you can press M to raise them and N to lower them. Each M key stroke will raise the road by 6 meters. For the first 2 key strokes, the road will be on top of a retaining wall. After 3 or more M key strokes, bridges will form underneath the roads. These roads can be constructed above pre-existing roads and other structures. First few N key strokes will create a trench for the road to lie on. The next few N key strokes will create a tunnel for the road. Underground tunnels allow the player to construct roads underneath pre-existing roads and structures.  *By using the raise and lower road tools, players can construct multiple roads on top of each other.
