Since the reform and development, the driving force of the Chengdu-Chongqing region for the economic development of the west has been continuously strengthened. At 9 am on February 7, 2023, at the Ertang Wharf at the wellhead of the Shapingba District, drilling, cleaning, lowering of the reinforcement cage, and concrete pouring... Excavators are working in an orderly manner, and a pile foundation with a diameter of 2.8 meters and a length of 30 meters is going deep into the ground little by little. This is the construction site of the Jingkou Jialing River Bridge on the Chengdu-Chongqing Middle Line High-speed Railway.

"Since entering the field, we have been racing against time." Li Mo, the on-site technical director of China Railway Bridge Bureau, told reporters.

The Chengdu-Chongqing Middle Line High-speed Railway is a leading, iconic and demonstration project for the construction of the Chengdu-Chongqing economic circle. The construction of the entire line will start on November 28, 2022. After the project is completed and opened to traffic, the Chengdu-Chongqing dual-core can basically realize a one-hour direct connection .

At present, although there are three railways between Sichuan and Chongqing, the Chengdu-Chongqing Railway, the Yu-Sui Railway and the Chengdu-Chongqing Passenger Dedicated Railway (also known as the Chengdu-Chongqing High-speed Railway), they still cannot meet the high-quality travel needs of the masses.

In 2017, this direct passage for passenger transport with a design speed of 350 kilometers per hour and the most straight and efficient connection between the two places was included in the "Chongqing Medium and Long-term Railway Network Planning (2016-2030)".

Afterwards, under the background of the national strategy of promoting the construction of the twin-city economic circle in the Chengdu-Chongqing region, the project planning and construction "accelerated". From the survey and design bidding to the National Development and Reform Commission's approval of the feasibility study report, the project was implemented in just over a year. On November 28, 2022, the construction of the Chengdu-Chongqing Middle Line high-speed railway started, and the project blueprint became a "construction drawing".

The Chengdu-Chongqing middle line high-speed railway starts from Chongqing North Station, the hub of Chongqing, and introduces Chengdu Station, the hub of Chengdu. The total length of the main line is 292 kilometers, and some sections are reserved for further speed-up conditions. There are 8 stations on the whole line, including Chongqing North, Chongqing Science City, Tongliang, Dazu Rock Carvings, Anyue, Lezhi, Jianzhou, and Chengdu, benefiting nearly 30 million people.

"It plays an important supporting role in building a Sichuan-Chongqing integrated comprehensive transportation system, strengthening the leadership of Chengdu-Chongqing dual-core, regional linkage, jointly building the Belt and Road and the development of the Yangtze River Economic Belt, and promoting the formation of a new pattern of western development in the new era." City. The relevant person in charge of the Transportation Bureau said.

After the completion of this highly anticipated high-speed railway, it will bring along the line into the "one-hour traffic circle" in the Chengdu-Chongqing area, and will also form a dual high-speed railway channel in the Chengdu-Chongqing area with the Chengdu-Chongqing passenger train that has already been completed and operated.

A person in charge of the Tongliang District Transportation Bureau said that after the completion of the Chengdu-Chongqing Middle Line high-speed rail, Tongliang will end the history of no high-speed rail. At that time, it will only take 12 minutes from Tongliang to the central city of Chongqing, and only 40 minutes to Chengdu. In the future, the high-speed railway will also form a railway network in Tongliang District with the urban rail express line Bitong Line and the planned railway West Second Ring Road, and build a one-hour travel circle from Tongliang to important cities in the Shuangcheng economic circle.

A person in charge of Baoding Town, Dazu District said that the Chengdu-Chongqing Middle Line high-speed railway has a Dazu Rock Carvings station, which is 5 kilometers away from Dazu City and about 0.5 kilometers from the Dazu Rock Carvings Visitor Center. In the future, by high-speed rail, it will only take 15 minutes from Dazu to the downtown area of Chongqing, and just over 30 minutes to Chengdu. We expect more and more tourists to visit Dazu Rock Carvings by high-speed rail. Keywords: infrastructure, infrastructure construction, domestic engineering news, planning investment

Not only that, the Chengdu-Chongqing middle line high-speed rail will also greatly shorten the space-time distance between Chongqing and Shanghai and other Yangtze River Delta urban agglomerations. At present, it takes more than 10 hours to travel from Chongqing to Shanghai by high-speed rail. In the future, the Chengdu-Chongqing middle line high-speed rail will be connected with the Yuyi high-speed rail. It will only take 3 hours from Chongqing to Wuhan and 6 hours to Shanghai.
