Nanchang: Five Bridges Together to Accelerate Development

As the only provincial capital city adjacent to the Yangtze River Delta, Pearl River Delta and Haixi Economic Zone, Nanchang is the central city of the middle reaches of the Yangtze River and the node city of the "Belt and Road". The answer given by Nanchang is: insist on traffic first, speed up the construction of a comprehensive three-dimensional transportation system with "internal smoothness and external communication", and promote Nanchang to become an important strategic fulcrum for building a new development pattern in the country. The column "Work hard, strive for progress, race against time and fight for economy" is broadcast today: "Nanchang: Five Bridges Together to Promote Development and Speed Up".

High-standard planning guides high-quality construction. Last year, Nanchang City issued the Action Plan for Building a Strong Traffic City (2022-2025), constantly optimizing the urban road network, continuously unblocking the external communication channels, and planning and promoting a series of bridges and access projects across the Ganjiang River. Fuxing Bridge, Hongzhou Bridge, Longxing Bridge, Changnan Bridge and Tianxiang Bridge started planning and construction one after another, and "five bridges are on the same frame" above the Ganjiang River.

Longxing Bridge, located in Yangzi Island, consists of three river-crossing bridges: the main branch, the middle branch and the south branch of Ganjiang River, with a total length of 18.95 kilometers, including 4.957 kilometers in the joint construction section of highway and railway, and the upper layer is a two-way eight-lane urban expressway. The middle of the lower floor is a double-track high-speed railway; Both sides are two-lane urban main roads. Longxing Bridge is one of the key and difficult control projects of Changjiu High-speed Railway Project. It is an integral part of the Beijing-Hong Kong (Taiwan) channel in the national "eight vertical and eight horizontal" high-speed railway main channel and an important part of the North Second Ring Road of our city. Adding an important river-crossing passage in the north of the city will greatly alleviate the pressure of crossing the river of Hero Bridge and Ganjiang Bridge.

Cha Weixiong, director of the Institute of Transportation and Economics of East China Jiaotong University, said that the construction of Longxing Bridge not only strengthened the development on both sides of the Nanchang River, but also improved the construction of the urban ring road. The main frame of the high-speed rail in Nanchang, which is shaped like a rice, is declared complete. Let Nanchang metropolitan area fully integrate into the scope of the Yangtze River Golden Waterway Economic Belt.

At the same time, Nanchang’s "14th Five-Year Plan" put forward the urban spatial development orientation of "Nanchang to the south". The important passage in the south of Nanchang is being accelerated.

Reporter Yuan Changsheng saw at the scene that the scenery of "one river and two banks" is beautiful, and the construction of "Shuanglong Sleeping Wave" in the middle of Ganjiang River is in full swing. Fuxing Bridge and Hongzhou Bridge are important passages in the south of Nanchang, which not only run through Honggutan and Nanchang County, but also release the development space of Nanchang County, Honggutan and Xinjian District, and optimize the industrial development along the line. They are important links in Nanchang’s development strategy of "eastward, southward, westward, northward and zhongxing", showing the acceleration of "Hongzhou" and "revival".

Fuxing Bridge starts from the west side of Sanqingshan Avenue in the west and ends at the east side of Fusheng West Road in the east. The main line is about 4.7 kilometers long and the design speed is 60 kilometers per hour. After the completion of Fuxing Bridge, the distance between Jiulonghu Group and Liantang Group was shortened from 30 minutes to only 1 minute. The main line of the bridge is planned to be connected in January 2024, and it will be completed and opened to traffic in June 2024. At present, the cast-in-place construction of the pier on the west bank of the river-crossing section of Fuxing Bridge has been completed 100%, and the construction of the capping beam on the east bank has been completed more than 95%. The hoisting construction of the steel beam of the main bridge is under way. The steel structure of the main bridge of Fuxing Bridge is designed with 98 sections of steel beams, and the basket-shaped arch is designed with an inward inclination of 6 degrees. The constructor uses three-dimensional modeling technology to determine the posture of each section, and the installation error of each section should be calculated in millimeters. So far, 29 sections have been completed.

Xu Zhiwen, the site technical director of steel structure of Fuxing Bridge Project, said that under the premise of ensuring the installation accuracy and construction safety of steel structure, the investment in personnel and equipment should be increased, and efforts should be made to complete the construction task of steel beam of the main bridge of Fuxing Bridge as soon as possible.

Hongzhou Bridge, 3 kilometers south of Fuxing Bridge, starts from the west side of Dongxiang Road in the east and 350 meters west of Sanbaishan Road in the west. The main line is 3.94 kilometers long, of which the river-crossing section is 1.5 kilometers, connecting the East Outer Ring Road to the east and the West Outer Ring Road and Changli Expressway to the west. After completion, it can effectively relieve the pressure of shengmi bridge and Chaoyang Bridge crossing the river and divert the passenger and freight traffic pressure from Xiangyun Avenue to Changnan Avenue and South Outer Ring Road.

During the Spring Festival this year, more than 200 builders stayed in Changchun for the New Year. Facing the freezing temperature and biting cold wind, the builders on the river worked hard. At present, the pile foundation of Hongzhou Bridge has been completely completed, and the pile caps and pier columns are about 50% completed. We are racing against time to construct the main tower of Changzi, and strive to be completed and opened to traffic in September 2024.

Nie Kai, technical director of the West Coast Work Area of Hongzhou Bridge Project of China Railway Bridge Bureau, told the reporter that the workers ensured safety and quality, grabbed sunny days, fought rain and snow, and sprinted for the early completion of the main tower.

Along Fuxing Bridge on Fuzhou Street, to Donglian Road and Zhenxing Avenue, Nanchang city is unimpeded in the east-west direction. From Pingxiang Street to Hongzhou Bridge, take Xiaolan Avenue and Chenghu North Avenue, and the economic circles on both sides of the river will be more closely linked. The three bridges will connect the future science city on the west bank of the Ganjiang River with the Changnan area on the east bank of the Ganjiang River, Yaowan Wharf, Nanchang South Station and Nanchang land port, and the three-dimensional transportation system of public transportation, railway and water will be seamlessly connected, leading to the sea and witnessing the acceleration of "Hongzhou".

Cha Weixiong, director of the Institute of Transportation and Economics of East China Jiaotong University, analyzed that the development of the two sides of the Yangtze River in Nanchang will no longer be a bottleneck for the development of Nanchang, and at the same time, the two sides will be more closely connected and the traffic in Nanchang will be smoother. And the integration of the old industrial parks with the emerging industrial production level will make the development behind Nanchang more powerful and driving.

Bridges are the witness of Nanchang’s urban development, the symbol of Nanchang’s economic take-off and the vision of Nanchang’s future development. Bridges are an important part of Nanchang’s dynamic territory, an important carrier of harmonious coexistence between people and the city, and an important epitome of the mutual reflection of history and modernity. Now from north to south, Longxing Bridge, Hero Bridge, Ganjiang Bridge, Planning Erqi Tunnel, Bayi Bridge, Honggu Tunnel, Nanchang Bridge, Chaoyang Bridge, shengmi bridge, Dongxin Ganjiang Bridge, Fuxing Bridge, Hongzhou Bridge, Shatian Ganjiang Bridge, Fushan Ganjiang Bridge, Changnan Bridge, 15 river-crossing passages, a picture of "people walking and things flowing smoothly".
