Route description
In, Route 4 is a huge half-constructed road through a desert north of Castelia City. There are exits at the north and south. It starts off with a paved road which ends abruptly after fifty steps. Along the paved road are a number of large, half-done construction sites. To the west of the paved road by Castelia City's exit there is a large plot of deep sand and a cliff next to the ocean, with two fishing there. To the north of the cliff-lined sea there is an another half-done construction site. In the middle of the route, there are two paved roads; one that goes north towards Nimbasa City, and the other facing west and eventually north, leading to the Desert Resort. Over the path to Nimbasa City, just north of the incomplete intersection, there is an overhead freeway going east and west. Trucks can be seen passing over the freeway at high speeds.

Two years later, the road connecting Nimbasa City and Castelia City has changed substantially, and differs dramatically depending on the version that is played. In Black 2 the construction of a settlement along the road has been completed, along with the road having been completed. In White 2, the construction was abandoned after ancient ruins were discovered and excavated.

In both Black 2 and White 2, in the house at the most eastern or western part of the street, there is an NPC who will heal the player's party.

The route cannot be fully traversed until the player has defeated Burgh. In Black and White, a halfway along the paved road will turn the player back if the player does not have the badge from Castelia Gym. In Black 2 and White 2, several block the route halfway along the paved road; after the player has obtained three Badges, Colress will appear in front of the Crustle; after losing a battle against the player, he will operate his machine on the Crustle to make them disperse.
