Cai River Saltwater Intrusion Prevention Dam set for completion by year-end

The investor of the Saltwater Intrusion Prevention Dam project over the Cai River in Nha Trang is urging contractors to urgently mobilize machinery and equipment and accelerate construction to complete the project by the end of the year.

Progress accelerated

The construction site of the saltwater intrusion prevention dam on the Cai River in Nha Trang is bustling with activity around the clock. Workers and engineers are fully committed to accelerating progress while ensuring top quality and absolute safety for this key infrastructure project.

Nguyen Thanh Hien, Director of the Provincial Project Management Board (the project's investor), said, "Although land clearance for the project began in 2019, it was interrupted due to the Covid-19 pandemic. With the determination of the relevant agencies, all land clearance work for the project was completed and the land was handed over to the contractor for the construction by June 2025. With all challenges resolved, the project is now entering its final phase."

Completion scheduled in December

The project has completed reinforced concrete work for the main dam and boat lock, installed hydraulic cylinders, dam gates, and boat lock gates, and finished all 8 reinforced concrete bridge piers. Contractors are accelerating progress on several components, including riverbed reinforcement and embankment stabilization (95% complete); girder installation and reinforced concrete deck and superstructure of the traffic bridge (95% complete); technical infrastructure and ground leveling on both banks (90% complete); and the operation building (97% complete).

The construction has been 92%complete so far. Construction is progressing on the approach roads at both ends of the bridge, along with technical infrastructure, landscaping, and the completion of the SCADA system, electrical systems and lighting.

Operational training and trial runs are planned for November, with project completion and handover scheduled for December. To stay on track, the investor has deployed management staff to oversee on-site construction and instructed the supervision consultant and contractor to boost manpower, materials and equipment to accelerate progress and meet the deadline.

According Nguyen Thanh Hien, in addition to accelerating construction progress and ensuring project quality, the disbursement of public investment capital for this project is also very important. The management board has proactively developed a specific plan for each month and quarter, closely following the implementation progress and actual payment needs. The cumulative capital disbursement for 2025 up to October 24 is VND38.64/50 billion, reaching 77%. Full disbursement is expected by November.

This project was inaugurated to celebrate the 18th Congress of Khanh Hoa Provincial Party Committee, term 2020-2025, and is one of the province's key projects. The dam is being built 75 meters downstream from the railway bridge in West Nha Trang Ward with five sections, each 30 meters wide, including a navigation lock and a combined road bridge on top. The total length of the bridge is 400 meters, consisting of 9 spans; the bridge is 26 meters wide, designed for two-way traffic, with pedestrian walkways on both sides, 1.75 meters wide each.
