abstract
The newly-built Nanchang-Ningdu expressway Shang Gang-Ningdu section project is a planned construction project in Several Opinions of the State Council on Supporting the Revitalization and Development of the Former Central Soviet Area such as Gannan, and it is an important section of the "four vertical, six horizontal and eight radial" highway network in Jiangxi Province. Because it is parallel to the existing Jiangxi-Guangdong corridor, it will share the vertical traffic flow between the north and the south of our province and alleviate the increasingly tense traffic pressure between the north and the south. Improve the bottleneck of insufficient access to the vertical expressway in the south-central region of our province, enhance the access and supply capacity of the provincial capital and the Pearl River Delta region, meet the needs of the open development of Poyang Lake Ecological Economic Zone, and promote the economic development in the south-central region of our province.
