Almost every time a bus from one city or province enters into another (usually near the very end of the route), there is only the type of sign that the new area uses. This bus stop is in Gijang (기장군) which is the orange and blue sign. But the yellow and blue one is the Ulsan (울산) type. There are a few other stops in this area that have both of these types of signs. But I can't recall another place in Korea (although it probably exists) that has two differing signs from two areas.
