At the same time, it is difficult for some highways to adapt to the economic and social development and the travel needs of the people, and slow traffic on some sections has become a norm, limiting the overall efficiency of the road network. The relevant person in charge of the Provincial Department of Transportation stated that in order to alleviate the traffic pressure on national and provincial main roads and optimize the road network structure, it is urgent and imperative to carry out expansion and transformation of relevant highways.
One way, two lanes have become four lanes, the road is wider, the speed is faster, and the efficiency is also higher. "Xiao Jin, a truck driver who has been driving on the Beijing Shanghai Expressway all year round, told reporters in the Gaoyou service area. From the north of Jiangsu to the central and south of Jiangsu, it is now possible to quickly reach Shanghai by connecting the Shanghai Wuhan Expressway from the Zhengyi Link to the east, or by connecting the Jiangyi Expressway and the Shanghai Chengdu Expressway southward along the Wufengshan Yangtze River Bridge to Shanghai or Zhejiang.
Deng Dongsheng, Secretary of the Jiangsu Traffic Control Party Committee and Chairman, stated that the Beijing Shanghai renovation and expansion project is the largest investment scale, longest construction distance, and highest functional positioning project in the single project of Jiangsu's new era expressway. As the "backbone" of the province's expressway sector, the completion of the project plays an important supporting role in the implementation of strategies such as the development of the Yangtze River Economic Belt, the integration of the Yangtze River Delta, and the "1+3" key functional areas in Jiangsu. Jiangsu Traffic Control will further focus on scientific control, digital scheduling, precise rescue, and quality services, continuously improving the public's sense of "fast and smooth" and "quality service" experience.
After the opening of the expansion project of the Xinyi Jiangdu section of the Beijing Shanghai Expressway, the effect was immediately successful. "The relevant person in charge of the Provincial Department of Transportation stated that from the projects completed in recent years, the expansion and renovation have played a positive role in improving the level of highway traffic service and promoting regional development. For example, at the end of last year, the expansion project of the Liucun Interchange to Tongjing Town section of the Ningma Expressway renovation and expansion project passed the handover inspection, and the section was fully opened and put into use. In addition, the previously completed and opened Liucun Interchange to Youfangqiao overpass section of the Nanjing section of the Ningma Expressway renovation and expansion project achieved full opening. The expanded Ningma Expressway can only increase its traffic by nearly three times, which not only facilitates residents along the line, but also tightens the metropolitan area.
At present, the renovation and expansion of Jiangsu expressways have entered a concentrated period of accelerated construction, and the ongoing renovation and expansion projects are being pushed forward rapidly.
