The highest spiral overpass in southwest China's Chongqing

The photo shows Sujiaba overpass, the highest ramp bridge at 72 meters away above the ground, as seen in southwest China's mountainous Chongqing, on October 13, 2017. If you stick your head out of the car window while on the bridge, it feels like you are hanging in the air, just like riding in a roller coaster. [Photo: IC]
