As the two major cities in the west, Chengdu and Chongqing are about 300 kilometers apart. For the two major cities to integrate and develop, transportation infrastructure is essential.

At present, Chengdu-Chongqing, Chengdu-Chongqing-Chongqing and Chengdu-Chongqing expressways have been opened, and the fourth expressway, Chengdu-Chongqing Expressway, is under construction. On January 7, reporters from West China Metropolis Daily and Cover News interviewed two experts from Sichuan Highway Planning Survey and Design Research Institute Co., Ltd. (hereinafter referred to as "Sichuan Highway Design Institute Company") and analyzed from the perspective of highway network planning. The existence of the four expressways will bring benefits to the development of the Chengdu-Chongqing Shuangcheng Economic Circle.

Three high speeds have been opened to greatly reduce the space-time distance between the two places

Liu Jiashun, Chief Engineer of the Fourth Branch of the Sichuan Highway Design Institute, has participated in the construction of Chengdu-Chongqing Expressway, the earliest expressway connecting Chengdu-Chongqing. He told reporters that the Chengdu-Chongqing Expressway was the first expressway in the early stage of the country's reform and opening up, and the first expressway in Sichuan Province. The advantages are complementary and develop in synergy. "He said that the Chengdu-Chongqing Expressway is 340 kilometers long and the car runs for about 4 hours, greatly reducing the space-time distance between the two places.

Liu Jiashun said that strictly speaking, the Chengdu-Chongqing Expressway has low technical standards and limited capacity, which also lays a foundation for the subsequent construction of expressways in Chengdu-Chongqing.

According to him, in 2007, the second expressway connecting Chengdu and Chongqing, Chengdu (Du) Sui (Ning) Expressway was officially completed. The distance from Chengdu to Chongqing was reduced to 310 kilometers, and the car operation required 3 hours.

In 2017, the third expressway that directly connected Chengdu-Chongqing—Cheng'an-Yu Expressway was officially completed. This is also the shortest highway passage between Chengdu and Chongqing. The total length is about 280 kilometers, and the car will run for about 2.5 hours. It has also shortened the space-time distance between Chengdu and Chongqing to the extreme, which has strongly promoted personnel exchanges and logistics development between the two places, and promoted the economic development of the two places and along the line. "Liu Jiashun said.

Article 4 High speed is under construction and will serve the development of the Twin Cities Economic Circle

And another expert who has been engaged in road planning and design for many years, Qiao Jianqiang, Dean of the Third Branch of the Sichuan Highway Design Institute's Survey and Design Institute, took out a map of Chengyu District and told reporters that in addition to Chengyu, Chengsuiyu, and Chenganyu, three highways have been opened. The fourth expressway, which directly connects Chengdu and Chongqing, is under construction. The high-speed survey and design work is the overall responsibility of the branch.

"As the fourth directly connected expressway between Chengdu and Chongqing, Chengdu Ziyu Expressway is connected to the new airport expressway at the Three-Round Jiangyuan Interchange. It first passes Jianyang and then Ziyang and connects to Taonan District of Chongqing." Qiao Jianqiang said In terms of planning and design, the Chengdu-Zhejiang-Chongqing Expressway is of great significance. It not only connects the two major cities of Chengdu-Chongqing, but also connects the Tianfu International Airport currently under construction with Chengdu and Chongqing urban areas. Residents of the two places pass this highway. , You can take the flight more conveniently.

Undoubtedly, this will be another busy highway between Chengdu and Chongqing. "According to the plan, the Chengdu-Zhejiang-Chongqing Expressway is planned to be open to traffic this year (2020)," he said.

Qiao Jianqiang introduced that between Chengdu and Chongqing areas, there are four expressways that directly connect the two places, and they are not counted as detour routes such as the Chengdu-Chongqing Economic Zone ring road. In Chuzhou, Neijiang, Guang'an, and Dazhou, adjacent to Chongqing, there are expressways connected to each other, including the Rong (Chang) -Qing (Zhou) Expressway just opened.

Qiao Jianqiang believes that, including the three expressways that have been opened and the Chengdu-Zhejiang-Chongqing Expressway under construction, from the perspective of the planning and design of the expressway, the space-time distance between the two places will be further shortened to facilitate the exchanges between the residents of the two places. Secondly, the intensive highway construction has also created excellent external conditions for logistics exchanges and economic exchanges between the two places.

With the development of highway encryption network, including east-west direction and north-south direction, the road network is denser and more areas pass through. It also more closely integrates the two places of Chongqing, especially the convergent development of urban agglomerations. A solid foundation has been laid for the development of the urban economic circle.
