Majority of citizens privilege natural environment in “space” along the Han River.However, expressway along the river cuts the city into parts, because Seoul Metropolitan Government makes the urban planning for traffic than pedestrians.As closer to the Han River, the number of closed buildings increases, making the street environment more desolate.
