Location

Original Bridge

Construction of the original bridge began in November 1977. The bridge cost RMB 64.68 million and was opened to traffic on the 1st of July 1980. The bridge was the first road bridge over the Yangtze River in Chongqing. The bridge carried two lanes of traffic in each direction.

Second Bridge

In 2003 construction began on the second four lane bridge to the west of the existing bridge to meet growing traffic demands. The new bridge was completed in 2006 at a cost of approximately US$40 million.[3] The main span of the new bridge was manufactured in the Wuchang District of Wuhan. It was sealed and was towed over 1,000 kilometres (620 mi) upstream to Chongqing. Placement of the piers due to the close proximity to the existing bridge necessitated a longer span; the bridge's main span of 330 metres (1,080 ft) makes it the largest box girder bridge in the world, displacing the previous record holder, the Stolma Bridge.[4] When the bridge was opened southbound traffic was moved onto the new bridge and all four lanes of the original bridge were used for northbound traffic.
