Puqian Bridge (铺前大桥) is an under-construction cable-stayed bridge east of Haikou City, Hainan, China.[2][3] It will cross the entrance to Dongzhai Harbor and is being built to provide quicker access to Wenchang, a large, administrative division of Hainan province. (The area of Wenchang contains the city of Wenchang further south.) The bridge is expected to reduce travel time from Haikou to Wenchang City from 90 minutes down to around 20 minutes.[4]

Location

Location map

The eastern end of the bridge terminates at the town of Puqian with the western end at a small island named Beigangdao (literally "north port island") containing a few villages including Hou Xi Village. A road bridge is being constructed to connect the short distance between the western end of the island and a peninsula, the western shore of Dongzhai Harbour. Another main road is being constructed from the tip of this peninsula westward to the Nandu River. There it will connect to the Haikou New East Bridge that serves as the beginning of the Haidian No. 5 East Road which leads through Xinbu Island and into Haidian Island, part of Haikou City.

Construction

Main pylon

The Puqian Bridge is a single-pylon, double-plane, steel box girder, cable-stayed bridge.[5] The entire length of the bridge will be 5,600 metres long and 32 metres wide. The main span will consist of two, 230-metre sections, one on each side of the pylon.[1] The deck will be steel with a flat, closed box cross section 37.3 metres wide and 3.3 metres deep.[6] The surface will contain a two-way, six-lane road.[5]

Because the Puqian Bridge crosses over a geological fault line, it is being built to withstand earthquakes.[4]

Timeframe

Construction of the Puqian Bridge began on March 7, 2015 and is scheduled for completion by the end of 2018.[7] The estimated cost is 3.01 billion Renminbi ($440 million).[4]
