The Nanpu bridge is the world’s fourth longest cable stayed bridge. In addition, 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. Furthermore, this is in order to reduce the amount of land used. The designers did a great job at using the smallest amount of space as possible.
Designed by a collective approach was this bridge. Shanghai Urban Construction Design Institute, Shanghai Engineering Design Institute and Shanghai Urban Construction College designed it. Yangpu Bridge's sister bridge is this one. Also, this bridge is also one of the main bridges in Shanghai.
The methodology used is Composite beam structure. Furthermore, the bridge crosses the Huangpu river. Also, the bridge is divided into six vehicle lanes with sidewalks of two meters wide, on both sides along the bridge.
I think this bridge and interchange is one of the coolest I have ever seen in the world. One day I would love to visit it. What do you think of this interchange? It seems like it could be very much too handle for many people. Older folks are some of the people who may not want to drive on this.
