Important significance

Yongchuan, as the central city in western Chongqing, is the bridgehead and important strategic fulcrum for the implementation of Sichuan-Chongqing economic cooperation. Luzhou, Yibin, Zigong and Neijiang are important industrial bases in Sichuan Province. They are closely related to Yongchuan in transportation, industrial development, logistics, people flow and information flow, and are the key breakthrough areas and strategic platforms for Chongqing and Sichuan to implement Sichuan-Chongqing economic cooperation. Therefore, the construction of Yongchuan Yangtze River Highway Bridge is the need to implement Sichuan-Chongqing economic cooperation and build the traffic circle of Sichuan-Chongqing Golden Triangle. The construction of Yongchuan Yangtze River Highway Bridge will help Chongqing to speed up the construction of the shipping center in the upper reaches of the Yangtze River. Yongchuan Port Area of Chongqing Port has good conditions for deep-water wharf construction, and it is one of the five key ports planned and constructed in Chongqing. The construction of Yongchuan Yangtze River Highway Bridge can realize a high-speed and fast land-water combined transport system.

After the completion of the bridge, Chengdu-Chongqing Expressway, Chongqing-Luzhou Expressway, Chongqing-Guizhou Expressway and Yongchuan Port Area of Chongqing Port will be closely connected in series, which will help to create a new convenient sea passage in western Chongqing, accelerate the construction of the shipping center in the upper reaches of the Yangtze River in Chongqing, and realize a high-speed and fast land-water combined transportation system in Chongqing. At the same time, it will also connect industrial production bases, mineral resources development bases, modern agricultural development zones, tourism trade and various resource factor markets in Yongchuan, Jiangjin, Luzhou, Hejiang, Chishui and Guizhou in a wider field and at a higher level, which is of great significance to promoting the rapid economic development of southwest Chongqing, southeast Sichuan and northwest Guizhou.
