As an important transportation hub in Changchun, the capital city of Jilin Province in northeast China, the Changchun Ecological Square connects three districts: Jingyue High-tech District, Economic Development District and Nanguan District. The overpass at Changchun Ecological Square sees a huge daily traffic volume of vehicles, enabling rapid commutes for people in the three major regions. Viewed from high above, the entire square is shaped like two giant shuttles stacked on top of a huge ring, symbolizing the economic vitality of the city.
