The Longzhouwan tunnel, an important transverse link in the southern part of Chongqing's main urban area, was opened to traffic on Nov. 5, 2019, according to China Construction Fifth Engineering Corporation. The opening of the Longzhouwan tunnel will further improve the traffic pattern in the southern part of the main urban area and speed up the integrated development of the metropolitan area.

In addition, the tunnel has been decorated with paintings of blue sky and white clouds, which, aside from beautifying the tunnel, will help effectively relieve driver fatigue.

This project is the first bridge-tunnel Public-Private Partnership (PPP) project built in the main urban area of Chongqing. The total investment of the project is nearly 4 billion yuan. The full length of the main project line is about 8,000 meters, including three tunnels, four flyovers, a bridge, and an undercrossing tunnel. The total length of the main line is about 4 kilometers, not including the ramp of the undercrossing tunnel. The design speed of the project is 60km/h, with three lanes in both directions.

This project will improve the transportation network in the southern part of the main urban area. Longzhouwan tunnel and its east-west extension line can realize inner and outer ring connections through rapid transformation, accelerate the development pace of Banan district, and improve the traffic network pattern in the southern part of Chongqing's main urban area.

Longzhouwan tunnel is the primary channel connecting the Chongqing-Hunan expressway, Chongqing-Guizhou expressway, circum-city expressway and Yunan Avenue S106. It is also an indispensable fast channel connecting the economic development zone, Banan Economic Park, logistics base and Jiang Jin Luohuang Industrial Park. After the completion of the project, the Chongqing highway logistics base will be promoted to realize multimodal transport.
