Qiwan Avenue will undergo a rapid transformation this year, and the plan is currently made public. An interchange, four underpass tunnels and an overpass bridge will be built to speed up the traffic flow of Qiwan Avenue, in addition to six east-west crossings for pedestrians.

The Qiwan Avenue Rapid Transformation Engineering starts at Sanjiao Expressway, crosses over the North Outer Ring Interchange connects with the Qijiang River Tunnel, and intersects with 21 roads including Haojiang Road West, Shiji Avenue, Kanghua Road, Sunwen Road East, Zhongshan Road, Bo'ai Road and Xingwen Road, and then finally connects with the Jinzishan Tunnel and ends at Tanzhou Expressway.

The engineering stretches across 9.796 kilometers, including a 856-meter tunnel section under Qijiang River in the Shiqi Headquarters Economy Zone. Qiwan Avenue will be constructed as a two-way eight-lane urban arterial road, with a speed limit of 60 km/h.

The plan includes a 2,090-meter-long tunnel under Qijiang River. It is the longest tunnel in the rapid transformation engineering. In addition, Qiwan Avenue will cross over Bo'ai Road and Xingwen Road through bridges, with a total bridge length of 727 meters.
