After 14 months of construction, the Khanh Binh Bridge—the longest bridge on the Van Phong-Nha Trang Expressway—has been successfully completed.
Located at Km 346+756 of the Van Phong-Nha Trang expressway, the Khanh Binh Bridge has four lanes with a width of 17.5 meters, and a total length of nearly 700 meters, comprising 17 spans. The project was completed at VND 206 billion.
The bridge spans Provincial Road No. 8 and a mountainous valley in the northeast of Khanh Binh Commune, Khanh Vinh District, Khanh Hoa Province. Construction began on July 20, 2023, immediately after the site was handed over. The original contract scheduled a 34-month timeline for the bridge.
Previously, challenges arose due to the difficult terrain and the presence of thousands of square meters of forest, requiring changes in the project scope. Site clearance delays extended the project by 7 months.
The M2 pier's location in high mountains posed transportation difficulties, and geological discrepancies required additional drilling to adjust the bored pile lengths. These complications risked slowing down the overall progress of the Van Phong-Nha Trang Expressway.
Vinaconex contractor worked closely with Project Management Unit No. 7 (project’s investor) and Tram Huong Forestry One Member Co., Ltd. (forest owner) to coordinate site clearance. With approval from the Department of Agriculture and Rural Development and Khanh Hoa’s People’s Committee, the necessary areas were cleared, allowing construction to resume.
The presence of telecommunications infrastructure and a 22KV power line crossing the N2 span also created obstacles. Vinaconex collaborated with Khanh Vinh Power Company to relocate these utilities, ensuring a safe construction environment and minimizing delays.
As the largest bridge on the expressway and a critical link for the project, the timely completion of Khanh Binh Bridge is expected to boost the overall progress of the Van Phong-Nha Trang Expressway project.
The contractor has deployed multiple teams working around the clock, including nighttime shifts. After 14 months of intensive work, the installation of the 17th-span girder has been completed, marking a major milestone—the completion of Khanh Binh Bridge. Currently, over 90% of the bridge's total construction volume has been achieved.
According to Engineer Tran Minh Tan, project commander, the contractor has mobilized machinery, equipment, and two teams to construct the bridge deck, one team to install expansion joints, and another for assembly tasks. As the rainy season approaches, all teams have been working simultaneously to maximize productivity.
Following the completion of Khanh Binh Bridge, the contractor quickly moved on to deck construction, railing installation, and concrete pouring, with plans to begin asphalt paving soon. The aim is to finish the bridge by December 31—10 months ahead of the promised timeline.
The Van Phong - Nha Trang Expressway project, spanning 83 kilometers through four districts—Van Ninh, Ninh Hoa, Dien Khanh, and Khanh Vinh—has a total investment of over VND11,800 billion. Construction commenced in January 2023.
At present, 30 construction sections are operational (21 road sections and 9 bridges), employing nearly 1,400 workers and utilizing around 800 pieces of equipment. The project has already achieved 70% of its contracted construction value and is projected for completion by April 30, 2025 (8 months ahead of schedule).
