Overcoming the limitations of the embankment foundation.<\/strong><\/p>\n\n\n\n

Dr. Phan Huu Duy Quoc, Chairman of the Board of Directors of Construction Corporation No. 1 \u2013 JSC (CC1) and Deputy Secretary General of the Vietnam Concrete Association, believes that elevated bridges are an inevitable choice if the delta and the livelihoods of tens of millions of people are to be protected. In reality, traditional highways built on embankments are facing three major bottlenecks in the Mekong Delta: material shortages, negative impacts on the ecosystem, and risks from climate change. Sand resources from the upper Mekong have decreased to only 1\/10 of what they used to be. Massive river sand mining causes erosion, while the use of untreated sea sand leads to salinization of arable land. Furthermore, these high-embankment roads inadvertently become "dikes" dividing the delta, hindering water flow, preventing sediment deposition, and disrupting the natural balance. In the context of rapidly rising sea levels and subsidence, these embankment roads face the risk of damage and require costly maintenance.<\/p>\n\n\n\n

According to Mr. Quoc, if only the initial construction cost is considered, elevated bridges seem more expensive. However, considering the project's lifespan \u2013 including maintenance, depreciation, natural disaster risks, and opportunity costs due to delays \u2013 elevated bridges are superior. The structure is less prone to damage, does not require subsidence compensation, has a design lifespan of 100 years, and is almost immune to major floods and saltwater intrusion.<\/p>\n\n\n\n

Expressways like the Chau Doc - Can Tho - Soc Trang route can "pass through" hundreds of canals and waterways without disrupting the terrain. This is a unique advantage that embankment roads struggle to achieve, especially when a rapid and synchronized infrastructure network needs to be completed.<\/p>\n\n\n\n

Dr. Pham Viet Thuan, from the Institute of Resource and Environmental Economics in Ho Chi Minh City, commented: "Vertical bridges demonstrate a superior advantage in areas with weak soil conditions like the Mekong Delta and should be implemented immediately. Around the world, many countries such as China, Thailand, and Singapore have been implementing this approach for a long time."<\/p>\n\n\n\n

From technical solutions to strategic vision<\/strong><\/p>\n\n\n\n

Many experts believe that elevated bridges will help shorten construction time and minimize maintenance costs later on. However, without a comprehensive strategy for the Mekong Delta, infrastructure development will be fragmented, with each area having its own style, lacking coordination and efficiency.<\/p>\n\n\n\n

Hoa Binh Construction Group Co., Ltd. is currently implementing a short-slab girder bridge solution on high-strength prestressed concrete (PRC) piles \u2013 a technology optimized to adapt to weak soil conditions, within depths of less than 30m. PRC piles are made from C80 prestressed centrifugal concrete, reinforced for increased ductility and lateral load resistance, with diameters of 700-1,000 mm. C60 concrete girders with ribs, spans of 9-12 m, are lightweight, easy to lift and install, and do not use bearings or expansion joints, thus reducing maintenance costs. The C35 concrete bridge deck is cast in place, seamlessly connected to the girders, enhancing durability and stability.<\/p>\n\n\n\n

Dr. Phan Huu Duy Quoc stated: \u201cCC1 is leading a Bridge Solutions Research Group comprising 10 domestic and international companies. The solutions proposed will be highly flexible and suitable to the actual conditions of each region, adapting to all types of terrain and geology. This initiative not only creates practical value for transportation infrastructure projects but also demonstrates a commitment to contributing to the sustainable development of the country. At the same time, it becomes a great source of inspiration for the business community in the construction industry, promoting cooperation and innovation.\u201d<\/p>\n\n\n\n

If elevated bridges are considered a national infrastructure strategy for the Mekong Delta, the benefits will extend far beyond transportation. They will boost the domestic construction materials and bridge engineering industries, promote technology localization, and create a "Make in Vietnam" supply chain from high-strength concrete to girder structures and construction equipment.<\/p>\n\n\n\n

Several projects have demonstrated the feasibility of elevated bridges. The current challenge is to move from experimental sections to simultaneous implementation, linked to the overall regional transport plan, connecting with waterways and roads, logistics development, and urban-rural integration.<\/p>\n\n\n\n
