Which company built the expressway from An Wei to Poyang?

I would like to ask which company built expressway from Anhui to Poyang. Anhui to Poyang expressway is invested and constructed by Chizhou Municipal Transportation Bureau. The name of Anhui-Poyang expressway Project is S27 East to Poyang expressway Chizhou Section Project. This project is located in Chizhou City, Anhui Province, and invested and constructed by Chizhou Municipal Transportation Bureau. The starting point of the route of this project is located in the southeast of Huayuan Township, and a landing hub is set to connect with Anjing Expressway. From north to south, the route passes through the south of Huayuan Township, the east of Guangang Town, the east of Nixi Town and the east of Zhaotan Town, crosses Longquan River and G236 in the south of Zhaotan Town, and then continues to drive south to the end of the project. The end point is located at the Anhui-Jiangxi border on the east side of Longquan Town, and connects with the Jiangxi section of Poyang Expressway from east to east. The total length of the route is about 49.620 kilometers.
