On August 18, the Quxi River Double-Track Super Major Bridge, part of the new Chongqing-Wanzhou High-Speed Railway (referred to as the “New Chongqing-Wanzhou High-Speed Railway”), was successfully connected, laying a solid foundation for the full line’s timely opening.

The New Chongqing-Wanzhou High-Speed Railway is part of China’s “Eight Vertical and Eight Horizontal” high-speed rail network, specifically the Baotou (Yinchuan)-Haikou and Beijing-Kunming corridors. The line starts from Chongqing East Station, passing through Nan’an District, Banan District, Fuling District, Fengdu County, and Zhongxian County of Chongqing Municipality, and ends at Wanzhou North Station. The main line is 251 kilometers long with a design speed of 350 km/h.

The Quxi River Double-Track Super Major Bridge is located in Zhenxi Town, Fuling District, Chongqing, crossing the Quxi River, a tributary of the Yangtze River. It is approximately 953 meters long and is a key and challenging project on the entire line. The bridge is situated in a hilly river valley slope area with steep terrain, and adverse geological conditions such as dangerous rocks, falling stones, and landslide bodies.

To address this, the project construction team carefully planned and developed construction plans for the steel trestle bridge and the continuous beam. Before work began, specialists were assigned to meticulously inspect and accept processes such as template installation for the closure segment, rebar binding, and counterweight configuration for the closure segment. On-site safety and technical support were strengthened, and strict control was maintained over key processes to ensure orderly progress of the construction.

After the New Chongqing-Wanzhou High-Speed Railway is completed and opened, it will strongly promote convenient connections between the urban cluster of the Three Gorges Reservoir area in northeastern Chongqing and the main urban area of Chongqing, greatly facilitate travel for residents along the line, and drive economic and social development in the regions it serves.

Quxi River Double-Track Super Major Bridge

The Quxi River Double-Track Super Major Bridge is a modern railway bridge in China, a key infrastructure project built to support the nation’s expanding high-speed rail network. Its construction was a significant engineering feat, designed to carry two parallel rail tracks across the challenging terrain of the Quxi River valley.

Chongqing-Wanzhou High-Speed Railway

The Chongqing-Wanzhou High-Speed Railway is a major railway line in China that connects the megacity of Chongqing to the district of Wanzhou. It was constructed to drastically reduce travel time through the mountainous terrain of the Three Gorges region, opening in 2016. This engineering feat is a key part of China’s national high-speed rail network, significantly boosting regional economic integration and development.

Eight Vertical and Eight Horizontal

I am unable to identify a specific cultural or historical site known as “Eight Vertical and Eight Horizontal.” This term does not correspond to any major world heritage sites, monuments, or well-documented cultural locations in my knowledge base. To provide an accurate summary, I would need more specific details or the correct name of the place.

Baotou (Yinchuan)-Haikou

“Baotou (Yinchuan)-Haikou” refers to the Baotou–Yinchuan–Haikou Expressway, a major national transport corridor in China. This modern highway connects the industrial city of Baotou in Inner Mongolia through Yinchuan, the capital of Ningxia, and extends thousands of kilometers south to the tropical island province of Hainan and its capital, Haikou. Its construction in the 21st century is part of China’s ongoing infrastructure development to improve connectivity and economic integration across its vast territory.

Beijing-Kunming

“Beijing-Kunming” refers to the Beijing–Kunming Railway, a major railway line in China that connects the capital city in the north with Kunming in the southwest. Its construction began in the early 20th century and was completed in phases, with the final section through the mountainous terrain finished in the 1960s. This vital infrastructure project was historically significant for integrating the remote Yunnan province with the rest of the country.

Chongqing East Station

Chongqing East Station is a major railway station in Chongqing, China, which first opened in 1952. It has since been modernized and expanded, now serving as a crucial high-speed rail hub connecting the megacity to other major centers across the country.

Wanzhou North Station

Wanzhou North Station is a major railway station in Wanzhou District, Chongqing, China, that opened in 2010. It is a crucial hub on the Yichang–Wanzhou railway, a vital section of the massive Shanghai–Wuhan–Chengdu passenger railway line. Its construction significantly improved transportation in the mountainous Three Gorges region.

Yangtze River

The Yangtze River is the longest river in Asia and a cradle of Chinese civilization, with a history of human habitation and irrigation dating back millennia. It has served as a major transportation artery and economic lifeline for centuries, profoundly shaping the country’s culture, agriculture, and commerce. Today, it is also the site of the monumental Three Gorges Dam, the world’s largest power station.
