Overcoming the sun and rain, determined to reach the finish line on time

At the construction site of the road bridge across the Red River border of Bat Xat (Lao Cai, Vietnam) - Ba Sai (Yunnan, China), these days, the construction atmosphere is bustling and urgent. The operating sounds of machinery and equipment along with the hurried work pace of nearly a hundred engineers and workers are working day and night through the sun and rain to ensure the construction progress of the Project.

The project started in March 2025, starting at Km0+015.61 (project route), in Ba Sai area, Ha Khau district, Yunnan province (China) and ending at Km0+440.71, Ban Vuoc border gate area, Bat Xat commune, Lao Cai province. The total global length is 330 meters, of which the Chinese side is 165 meters long, including abutment M1 and piers T6 to T7; the Vietnamese side is 165 meters long, including piers T8, T9 and abutment M2. The main bridge across the Red River is a low-tower cable-stayed bridge, consisting of three spans, 230 meters long, prestressed reinforced concrete beams, constructed using the balanced cantilever method combined with cable-stayed. The bridge tower is 20 meters high from the bridge deck, the global width is 35.3 meters.

The construction process on the Vietnamese side faced many challenges due to complex geological conditions and a bridge pier located in the middle of the Red River. The bored pile system is up to 60 meters deep and 2 meters in diameter, requiring high technology and specialized equipment. In addition, the prolonged rainy season causes strong currents, greatly affecting the progress and labor safety.

Mr. Do Tuan Cuong - Head of Project 2, Lao Cai Province Traffic Construction Investment Management Board said: “The current progress is slower than the original plan due to geological and weather factors. To overcome this, the Project Management Board has asked the contractor to increase equipment, organize overtime, and mobilize experienced technical staff to directly monitor the site. When the underwater structure - including the base, piles and pier body - is completed, the construction progress of the upper structure will be guaranteed. The goal is still to complete the project by September 2026, as agreed with the Chinese side.”

Construction strictly follows technical procedures to ensure labor safety.

At the construction site, Trung Chinh Construction and Trading Co., Ltd. - the construction unit on the Vietnamese side - is mobilizing maximum human resources, equipment and materials. There are currently two main construction teams: T9 pier on the shore and T8 pier base under the river. Talking to reporters, Mr. Ho Xuan Hung, technical officer of Trung Chinh Construction and Trading Co., Ltd., shared: "To ensure progress, we coordinate closely with the investor, focusing on speeding up the items. Workers work all day and night to ensure progress. In the next phase, we will mobilize more workers to ensure the project is completed as planned."

Construction is closely monitored according to regulations.

According to the Project Management Board, to date, the Vietnamese side has completed pier M2, all bored piles of pier T8 and T9, the project implementation value has reached about 17% of the total contract value. The contractor is focusing on constructing pier body T8, T9, striving to complete the entire underwater structure in 2025, creating favorable conditions for the construction of the upper structure in 2026.

Engineers and workers are working day and night through the sun and rain to ensure the project's construction progress.

The Project Management Board requires construction units to strictly comply with technical procedures, ensure labor safety, environmental sanitation and fire prevention. The construction area is equipped with signs, lighting systems and 24/7 safety monitoring. All materials and components are periodically inspected to ensure quality according to technical standards.

The contractor representative said that they will continue to apply advanced construction techniques to ensure labor safety, progress, quality of the project and compliance with technical requirements of both Vietnam and China.

The construction atmosphere is bustling and urgent.

When completed, the bridge will connect Ban Vuoc Border Gate Economic Zone (Vietnam) with Ba Sai Zone (China), forming a vital traffic route in the Kunming - Lao Cai - Hanoi - Hai Phong - Quang Ninh economic corridor, opening up new development space for the northern border region.
