Vinh Phu Bridge Project

The Vinh Phu Bridge adopts mixed cable girder technology (extradosed), a modern structural solution that combines cable stays and saddles, reflecting the application of advanced scientific and engineering innovations. This approach ensures both aesthetic appeal and technical excellence.

The project was managed with a high degree of transparency and strong inter-agency collaboration. Authorities from both Vinh Phuc and Phu Tho provinces were actively involved throughout the planning and implementation stages. Independent assessments were carried out by expert institutions, including the University of Transport, which served as the verification consultant, and the Ministry of Transport, which conducted the project appraisal. Oversight was also provided by the project investor and a dedicated supervision consultant. Notably, the local community participated in the monitoring process, contributing to enhanced accountability and transparency.

Sustainability and environmental protection were key priorities in the bridge’s design and execution. The bridge has a projected service life of 100 years, in accordance with international standards, ensuring long-term structural safety and durability. An artistic LED lighting system was installed to enhance energy efficiency and reduce maintenance needs. The bridge’s long-span design limits the number of in-river pillars, minimising disruption to water flow and helping to prevent riverbank erosion. Environmental impacts were carefully managed throughout construction, with a comprehensive monitoring plan in place. Construction waste was collected and repurposed for land levelling, domestic solid waste was sorted and directed to local landfills, and oil-based waste was safely stored and treated as hazardous material.

Before the bridge was constructed, residents on both sides of the Lo River depended on the Duc Bac ferry, which operated in areas with curved fairways that were prone to accidents. The ferry was not only inefficient but also presented significant safety risks. The completion of the Vinh Phu Bridge brought an end to ferry operations, significantly improving traffic safety and efficiency. On the Phu Tho side lies Viet Tri City, while the Vinh Phuc side is home to Duc Bac commune, a previously underdeveloped rural area. The new bridge has created a vital transportation link between these regions, fostering economic development, especially in Song Lo District.

In addition to its functionality, the bridge is architecturally symbolic. The extradosed design, which resembles two people leaning against each other, represents the spirit of brotherhood and solidarity between Vinh Phuc and Phu Tho provinces. This design is not only new to the area but also deeply meaningful, as the two provinces were once united as Vinh Phu.

The project aligns with FIDIC’s core values. In terms of integrity, it was managed with openness and accountability. Key documents such as the pre-feasibility study, feasibility study, environmental impact assessments, and project implementation plans were made publicly available. This ensured that decisions and progress were transparent to all stakeholders, including the public.

In terms of quality, the project met stringent national and international standards. Design quality management was implemented through an ISO 9001-certified system. The construction applied balanced cantilever techniques to reduce disruptions to river navigation, allowing the Lo River waterway to continue operating during the works. The bridge's modern structure and symbolic design further enhance its value as a piece of civil infrastructure.

The project also embodies sustainability through its durable, long-life design, its environmentally conscious construction practices, and its use of energy-saving LED lighting. It has significantly improved regional connectivity and quality of life while preserving the natural environment.

The Vinh Phu Bridge stands as a testament to high-quality engineering, environmental responsibility, and the enduring spirit of partnership between two provinces.
