Sichuan News Network, Chongqing, September 22 (Reporter Qiao Yongzhen)“Tale of Two Cities”: The Second Stop of the 2020 Chongqing Trip for National Online Media Reporters Arrived at the Chongqing High-Tech Zone to Visit the Science City Traffic Infrastructure Construction of West Chongqing (Chongqing). Several construction projects of the Western Science City (Chongqing) are understood to have advanced rapidly this year. In terms of transportation construction, under the leadership of the Chongqing Municipal Party Committee and the Municipal Government, the Chongqing High-Tech Zone Management Committee, which focuses on scientific issues, accelerates the pace of infrastructure construction and improves the structure system of the road network. , Linking the backbone of Chengdu-Chongqing development and moving towards the strategic goal of “Chongqing to the west, Chengdu to the east, Chengdu and Chongqing to meet.”
1. The original highway expansion project of Chengyu Expressway (Chongqing section)
The Chengdu-Chongqing Expressway runs through the interior of Chengdu and Chongqing. It is an extremely important transportation link between the two central cities of Chengdu and Chongqing and the major cities and counties of the two places. Since the completion of the Chengdu-Chongqing Expressway in 1995, it has fully demonstrated the importance of expressways in the transportation industry. The important position and function of the Chengdu-Chongqing economy has provided a solid guarantee of interconnection for the rapid development of the Chengdu-Chongqing economy and has become the “golden chain” for the social and economic development of the “Circle Chengdu-Chongqing Twin Cities Economy “. As the difference in traffic volume between the central areas of the two main cities of Chengdu and Chongqing continues to increase, the maladjustment of the Chengdu-Chongqing Expressway increases day by day, and it is difficult to meet the transportation needs of regional economic development and the construction of emerging industries. In order to continue to play the prominent role of Chengyu Expressway in the Chengyu “A Tale of Two Cities” chorus and improve its traffic capacity and service level. Currently, the road is planned to be expanded from the original four two-lane lanes to eight two-way lanes, and the design speed is increased from 80 km / h to 100 km. / h. The project is currently in engineering feasibility studies and construction is expected to begin next year.
2. High-speed train of Chengyuzhong Line
The Chengdu-Yuzhong Line High-Speed Railway is located within Sichuan Province and Chongqing City. The line will head east from Chengdu Hub of Chengdu Station, and will enter Chongqing Hub Chongqing North Station after Chengdu City Planning East New City, Lezhi County and Anyue County of Ziyang City, the Dazu District, Tongliang District, and Chongqing City Science City Station. The length of the main line of the line is about 292 km, of which the length of the line in Sichuan province is about 191 km, the length of the line in Chongqing city is about 101 km, the operating speed is 350 km / h and the long-term reserved pre-control is 400 km / h. The project is currently undergoing engineering feasibility studies and construction of the early start site in Chongqing is expected to begin next year.
3. Road construction
Within the City of Sciences, a total of 10 railway lines, five express lines and five general lines are planned, with a total length of about 288 kilometers. Among them, the existing railway lines in operation are Line 1 and Line 6 of the Metro, with a current mileage of 20.5km in the area; The project under construction is Metro Line 5 (Jiang Jump Line) with a mileage of 24km in the area, and the total mileage is completed. 60%; Line 7, Line 15, Line 17 and Line 27 have been included in the fourth round of Chongqing Rail’s construction plan, and all design bidding work has been completed, of which Lines 15 and 27 They are in preliminary design. The railway line 27 has started the land acquisition works in accordance with the time required by the Municipal Construction Committee and is scheduled to begin construction this year, line 15 is expected to begin construction next year and lines 7 and 17 advance in an orderly manner.
4. Mountain tunnel
Drive through the “westward obstruction” of Jinyun Mountain and Zhongliang Mountain. A total of 35 mountain tunnels are planned in the east-west direction of Science City, of which 19 pass through the Zhongliang Mountain Tunnel and 10 have been opened to traffic. The University City double-track tunnel and Taojia Tunnel are scheduled to begin construction in late November 2020, and the Baishiyi Tunnel is under pressure by 2020. Construction will begin before the end of December, and the Tuzhu tunnel is scheduled to go live before the end of October 2021; 16 of the Jinyun Mountain tunnels have been opened to traffic and the Jinfeng Tunnel is scheduled to begin construction at the end of November 2020. The Six Flags Tunnel will endeavor to complete in July 2021 before it begins.
5. Internal road network
One is to accelerate the construction of key arterial roads. The Hi-Tech Zone actively promotes the construction progress of key projects to help further open the traffic bottleneck of development to the west of Chongqing. Among them, the construction of Science Avenue (Phase 1) has begun; the main line of the western extension of the Huayan Tunnel was opened to traffic in June, and is planned to be full by the end of October 2020 Open to traffic; Hangu Interchange has completed the north-south connection line traffic conversion and is scheduled for completion in January 2021; The Xianglushan Tunnel, a controlled project on Pingshan Avenue, was completed ahead of schedule, and the project is scheduled to be completed in late October 2022. The second is to advance the preliminary study of the skeleton of the road network. The high-tech zone is accelerating the preliminary study of the skeletal road network, such as the Seven Vertical Lines, Yanshan Avenue, Xinsen Avenue and the eastern extension of Shanhu Avenue. Yanshan Avenue and Xinsen Avenue have carried out plan design work and plan to begin construction next year. The third is to promote the construction of unconnected passageways and sub-branch networks. The high-tech zone has systematically solved the network of roads and unconnected branches, has drawn up a special construction plan, and is accelerating the implementation in batches every year according to the priority and traffic demand.
“In order to promote the development of the transportation network, we are actively overcoming the transportation infrastructure bottleneck and carrying out the planning and construction of key infrastructure projects such as rail transit networks, tunnels and bridges, and we finally built a transportation system that is ‘integrated into a network, fast on the outside and smooth on the inside.’ Chongqing High-tech The competent person in charge of the district said that in the future, the exchange of various items such as talents, resources and industries will be more convenient and will strongly help accelerate the development of the economic circle of two cities in Chengdu-Chongqing.
