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. The main span of the new bridge was manufactured in the
Wuchang District of
Wuhan. It was sealed and was towed over 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 makes it the largest
box girder bridge in the world, displacing the previous record holder, the
Stolma Bridge. 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. ==Incidents==
