Dirt Road

 is a new tile introduced for the Wild West 2016 Event. They serve as another version of the normal Road tile. It is only available for players that unlocked it during the same event.

Trivia

 * Unlike normal roads, s cannot be placed over a River tile to create a bridge. Placing a Dirt Road over a river removes the river tile.
 * Stampy tends to gravitate to areas of dirt road, such as regions built during the Wild West event. As an African elephant, it makes sense that he would prefer a dirt road over hard asphalt.
