River

 Rivers are unique tile decorations. No items can be placed on top of rivers, excluding Roads. When a road tile overlaps a river tile (or vice versa), the two tiles create a bridge. A bridge can not be created with Pavement.

Trivia

 * Blinky can be seen in rivers, along with bobbing radioactive barrels.


 * There is a glitch in the game where barriers can be on rivers. The player must create a bridge over a river, then put the barrier on that and take away the bridge. If the player attempts to move the barrier from the river then, it will not be able to be placed back and the process must be repeated.
 * During the St. Patrick's Day Event, all river water turned from blue to green and then reverted back when the event was over.
