Route 4 connects Scraper City and West City. It is the shortest route of the region, with only a few kilometers in length. To the west, the outer arms of the Color River's delta are barely visible. To the east, the vision onto the far farmland is blocked by the highway between the big cities. Due to the wind mostly blowing from the West, the odor from the West Island Dump can be smelled in this town. The route is usually traversed by manual workers and motor bikers.
