One of the attractive characteristics of the bridge is the circular design that is being implemented in order to reduce the amount of land used. The famous Nanpu bridge was designed by the collective approach of Shanghai Urban Construction Design Institute, Shanghai Municipal Engineering Design Institute and Shanghai Urban Construction College. The Nanpu bridge is also called as the sister bridge of the Yangpu bridge, which is also one of the main bridges in Shanghai. The construction methodology implemented in the bridge is known as the composite beam structure. The bridge crosses the Huangpu river.
