Introduction of Changtong Expressway?

Changtong Expressway refers to the expressway from Nanchang to Tonggu County in Jiangxi Province, which is the Jiangxi section of Changsha-Nanchang Expressway. It is the most convenient passage from Nanchang to Changsha, nearly 100 kilometers more than Pingxiang Shanghai-Kunming Expressway. Zhong Da Consulting consulted various building websites and got relevant information about Changtong Expressway:

Nanchang-Tonggu Expressway is one of the local encrypted expressways in Jiangxi Expressway Network 18, and it is a fast passage between the central region and the developed coastal areas in the east, with a total length of about 170 km. The proposed project is Fengxin-Tonggu section of Nanchang-Tonggu Expressway. Most of the lines are in Yichun City, which shortens the time and space distance between Fengxin County, Jing 'an County, Yifeng County and Tonggu County, and greatly improves the hierarchical structure of the highway network in Yichun City.

Changtong Fengjing Expressway

English name: ChangTongExpressway

Chang-Tong (Fengjing) Expressway, namely Nanchang-Tonggu Expressway, is one of the local encrypted expressways in Jiangxi Expressway Network 18, and it is a fast passage between the central region and the developed coastal areas in the east, with a total length of about 170 km. The construction of this project is of great significance for alleviating the transportation pressure of Shanghai-Kunming Expressway, promoting economic exchanges between coastal economically developed areas and central areas, improving traffic conditions in various regions, and accelerating the process of economy, industrialization and urbanization in Jiangxi.

According to the requirements of the Jiangxi Provincial Party Committee and the provincial government, the Nanchang-Tonggu Expressway (Jiangxi-Hunan boundary) started construction in August this year. Changfeng Expressway, with a total length of 35.63 kilometers, is a section of Hangzhou-Chongqing Expressway in the waterway transportation development plan of the rising highway in central China. There are many bridges and tunnels in the whole line, and the bridge-tunnel ratio exceeds 25%. The project has the characteristics of high construction standard, difficult construction and high environmental protection requirements. The completion of Changfeng Expressway will greatly shorten the time from Nanchang to Fengxin, integrate into Nanchang's "half-hour economic circle", develop the regional economy of Jiangxi Province, and promote the economic take-off along the line and in the eastern part of Jiangxi Province.

2 Nanfeng Expressway Project Introduction Editor Nanchang-Fengxin Expressway is about 36.25 kilometers long, starting from K0+450 in Qingxi Village, Wangcheng Town, Xinjian County, connecting with planned Nanchang Chengxi Expressway (connecting Misheng Bridge), intersecting with Nanchang West Outer Ring Expressway, passing through Wangcheng Town, Shibu Township, Shibi Town, Anyi County, Huangzhou Town, Ningbu Township and Ganzhou Town, Xinjian County, and ending at K36+.

This project is the front section of Nanchang-Tonggu Expressway, and it is an important local encrypted expressway in the planning of expressway network in the rising area of central China and expressway network in Jiangxi Province. Nanchang-Tonggu Expressway is one of the local encrypted expressways in Jiangxi Expressway Network 18, and it is a section of expressway between the central area and the eastern coastal developed areas, namely (Hangzhou)-Dexing City-Nanchang-Tonggu County-Liuyang City-Changsha-Yiyang-(Chongqing). It connects Liuyang (Hunan-Jiangxi border) to Huayuan (Hunan-Chongqing border) expressway in the west and Dexing-Nanchang expressway under construction in the east, which, together with Dexing-Nanchang expressway, forms another convenient and fast passage across Jiangxi. Its construction has played a very important role in alleviating the transportation pressure of the Shanghai-Kunming Expressway and promoting the economic ties and exchanges between the economically developed coastal areas and the central region, and has been included in the waterway transportation development plan of the rising highway in central China organized by the Ministry of Transport.

The implementation of this project is not only the need of expressway network construction in central China and our province, but also a useful supplement to the national expressway network. Its construction shortens the time and space distance between the counties along the project and Nanchang City, and will be integrated into the "half-hour economic circle" of Nanchang City, which is conducive to the economic development of these areas, improving regional traffic conditions, alleviating regional traffic pressure, enhancing the radiation-driven role of Nanchang, the provincial capital, and enhancing the tourism advantages of Meiling-Tengwangge Scenic Area and Sanclaw Lun Scenic Area. And the development advantages of the five counties in coordinating the construction of Poyang Lake ecological economic zone, so as to further play the ecological advantages of Jiangxi.
