The Nanpu bridge is the world’s fourth longest cable stayed bridge. This is also the first girder bridge of Shanghai with a structural composition of steel and concrete. Before the year 1991, people used to communicate between Puxi and Pudong with the help of the ferry service. After the construction of the bridge completed in the year 1991, it connected Puxi to Pudong.
As per the reports, in the year 1991; the daily traffic was about 14,000 to 17,000 vehicles a day, and it increased to 120,000 vehicles per day as recorded in the year 2006. 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. The bridge is divided into six vehicle lanes with sidewalks of two meters wide, on both sides along the bridge.
