Changjiu Expressway This is the first expressway built in Jiangxi Province, and it is also a fully enclosed, fully interconnected, high-grade and multi-functional modern trunk highway in expressway. At present, it is designed as two-way eight lanes (only four lanes are built), which is very rare in intercity expressway (speed limit 100 km). Changjiu expressway is a world-leading expressway in information technology, with 6 interchanges, 3 separated interchanges 13, 4 river-crossing bridges and 9 passages 19. There are 2 main toll stations and 3 ramp toll stations. Changjiu Expressway has narrowed the distance between two megacities (Nanchang-Jiujiang). It will accelerate the integration process of Changjiu region and promote the rapid and coordinated economic development around Poyang Lake.
Overview information
brief introduction
Changjiu Expressway is the first expressway in Jiangxi Province, connecting Nanchang and Jiujiang. 1996 65438+ 10 opened to traffic. At present, most of expressway is a part of expressway, Yin Fu.
Changjiu expressway is the starting point of Jiangxi, Guangdong and expressway and an integral part of the national trunk line from Beijing to Fuzhou. It is connected to the foot of Lushan Mountain in the north and Jiujiang City, an important city in the middle and lower reaches of the Yangtze River, which is known as the thoroughfare of nine provinces, and Nanchang City, which is known as the world's dynamic city and international garden city. It is a fully enclosed, fully interconnected, high-grade and multifunctional modern main road in expressway. At present, it is designed as a two-way eight-lane expressway, which is very rare in intercity expressway. There are 6 interchanges, 3 separated interchanges 13, 4 river-crossing bridges and 9 passages 19. There are 2 main toll stations and 3 ramp toll stations.
Changjiu expressway is an important passage connecting Changjiu cities planned by the Ministry of Communications. It is a part of the National expressway Network and one of the radial trunk highways in Nanchang. Total length138km. The total investment of the project is 65.438+0.59 billion yuan, the subgrade width is 24.5 meters, the design speed is 654.38+000 kilometers per hour, the pavement is imported medium-grained asphalt concrete, the design load is 20% steam curing, -654.38+0.20, and it is fully enclosed and fully interconnected with two-way eight lanes (four lanes in some sections). There are 8 large bridges, 85 medium and small bridges, 2 large interchanges, 1 simple interchange 1 1, 3 management offices1,and 6 toll stations1. The traffic management system of the whole line adopts the latest international modern technology and is divided into four subsystems: toll collection, monitoring, communication, computer room decoration, power supply and lightning protection.
Before the Nanchang Games, Changjiu Intercity High-speed Railway will be opened to traffic one after another, bringing the distance between the two megacities closer. It will accelerate the integration process of Changjiu region and promote the rapid and coordinated economic development around Poyang Lake.
The development of history
We are now driving the Changjiu expressway from Nanchang to Jiujiang, which was built in 1989 and is one of the earliest expressway in China. Completed and opened to traffic in June 1996. But at that time, because Jiangxi's finance could not hold on, only one side was built, and the other side was later repaired by the state. 1996 65438+1On October 28th, Changjiu Expressway was completed and opened to traffic, achieving a zero breakthrough in the construction of expressway in Jiangxi. Since the completion of Changjiu expressway, it has played a great role in promoting regional economic development.
Historical significance
The opportunity brought by the construction of Changjiu Expressway echoes the important strategic deployment of the country to develop Pudong and open up along the river. Jiangxi Provincial Party Committee and Provincial Government made a strategic decision to build Changjiu Industrial Corridor. This has changed the overall economic framework of Jiangxi Province. After 10 years of construction, Changjiu Industrial Corridor has become the most dynamic area in Jiangxi Province.
After entering the new century, in the process of implementing the core strategy of industrialization and the main strategy of opening to the outside world in Jiangxi, how to strengthen the agglomeration, radiation and driving force of Changjiu Industrial Corridor and build the economic engine of Jiangxi's rise has once again attracted people's attention.
With the agglomeration and radiation capacity of Nanchang and Jiujiang greatly enhanced, Changjiu Industrial Corridor has ushered in new development opportunities.
To speed up the construction of Changjiu Industrial Corridor, it is necessary to reflect the requirements of "high starting point, high level, multi-orientation and openness", and build Changjiu Industrial Corridor into a new urban agglomeration with economic prosperity, industrial development, social civilization, cultural prosperity and beautiful environment in Jiangxi Province, an export-oriented economic demonstration zone with strong international and domestic competitiveness in the central region, an important advanced manufacturing base in the Yangtze River Economic Belt and an important strategic fulcrum for the coordinated development of the eastern, western and eastern economies.
Nanchang's economy and society have developed continuously and rapidly, with the secondary industry accounting for more than 50% of GDP, and the industrial-led economic growth pattern has taken shape initially; Jiujiang's economic development is also accelerating, the process of industrialization and urbanization is obviously accelerated, and the open economy is developing rapidly.
At the same time, the industrial cluster effect is also emerging, which makes the industrial foundation of Changjiu Industrial Corridor more solid. An industrial system supported by automobile, aviation and precision manufacturing industry, characteristic metallurgy and metal products industry, Chinese patent medicine and biomedicine industry, electronic information and modern household appliances industry, food industry, fine chemical industry and new building materials industry has been initially formed.
The whole province1580km expressway will fully form the "four-hour economic circle" in the province and the "eight-hour economic circle" in Changsha, Zhuhai and Fujian. In addition, Nanchang Changbei International Airport is built in the corridor, and there are more than 240 routes leading to major cities at home and abroad. Jiujiang Port is also an important hub port for east-west water transport and land-water transit between north and south, with the annual passenger traffic and cargo throughput ranking second and fourth respectively in Yangtze River Port.
