Access Ramp to the Nanpu Bridge, Shanghai
The Nanpu bridge is one of the two major bridges crossing the Huangpu River in Shanghai. Because of the strategic importance of the river as a navigation axis (Shanghai is the world's largest port in terms of tonnage) the bridge was set at a significant height, which required extensive access ramps. To minimize the spatial imprint of the ramp, it was built as a spiral on the Shanghai side of the bridge.
