Vietnam’s Ministry of Transport is set to significantly upgrade and expand over 10,600 kilometers of National Highway 1, a crucial north-south artery, with a substantial investment of approximately 10,650 billion VND (roughly $426 million USD). This ambitious project will focus on modernizing 12 sections of the highway and three key interchanges across eight provinces, enhancing connectivity and facilitating economic growth in the southern region of the country. The primary objective is to transform the existing two-lane roads into four-lane highways, significantly increasing traffic capacity and improving travel times.

The extensive upgrade initiative, which has received preliminary review and approval from the Ministry of Transport, will target vital sections of National Highway 1 passing through the provinces of Nam Dinh, Quang Ngai, Gia Lai, Dak Lak, Khanh Hoa, Tay Ninh, Dong Thap, and Vinh Long. This strategic enhancement aims to address current traffic bottlenecks and prepare the infrastructure for projected increases in freight and passenger movement. The decision to invest in these specific sections underscores their importance in the national transportation network and their role in connecting major economic hubs and agricultural regions.

Project Scope and Technical Specifications

The 12 targeted sections for upgrading and expansion are strategically located to address critical chokepoints and areas with high traffic volume. These include segments within Nam Dinh city, the city of Quang Ngai (specifically around the Bac Khac 2 bridge), and multiple locations in Gia Lai province such as Bung Xay, Pho Son, Ngo May, and An Nhon. Further enhancements are planned for Dak Lak province, encompassing Buon Ma Thuot city and the surrounding areas of Ban Thach, and in Khanh Hoa province with the Dien Khanh section. Finally, the project will also encompass upgrades in Vinh Long province itself.

The technical specifications for these upgraded sections are designed to meet modern highway standards. They will be developed to Class 3 highway standards, accommodating speeds of up to 80 km/h. The width of the carriageway will be expanded to four lanes, with the overall roadbed widening to 20.5 meters and the pavement surface extending to 14 meters. This substantial increase in width and lane capacity is expected to dramatically improve traffic flow, reduce congestion, and enhance road safety.

Key Interchanges and Strategic Connectivity

In addition to the highway segments, three critical interchanges will also undergo significant development. These include the Long Kim and Binh Nhat interchanges in Tay Ninh province, and an interchange serving the Tan Huong Industrial Park in Dong Thap province. The Long Kim and Binh Nhat interchanges are slated for a continuous flow design, prioritizing direct access onto National Highway 1, a significant improvement for traffic management. The interchange at Tan Huong Industrial Park will be designed as a grade-separated interchange, a crucial element for managing high traffic volumes and ensuring efficient movement of goods from the industrial zone to the national highway network. This specific interchange aims to streamline the flow of goods to the Tan Huong industrial zone, replacing the current system of traffic signals that often cause congestion and delays.

Investment Breakdown and Funding Sources

The total investment for this comprehensive upgrade project is estimated to be approximately 10,650 billion VND. This substantial sum is allocated across several key areas: around 6,020 billion VND will be dedicated to construction costs, 2,950 billion VND will be used for land acquisition and resettlement efforts, and the remaining funds will cover project management, supervision, and contingency expenses.

The project is planned to be financed through the national budget, aligning with the government’s commitment to infrastructure development. The envisioned timeline for the project is ambitious, with construction slated to commence in the third quarter of 2027 and completion targeted by the end of 2030. This phased approach aims to ensure efficient utilization of resources and minimize disruption to existing traffic flow during the construction period.

Background and Strategic Importance of National Highway 1

National Highway 1, also known as National Route 1A, is the backbone of Vietnam’s transportation system. Stretching over 2,300 kilometers from Lang Son province in the north to Ca Mau province in the south, it is the longest highway in Vietnam. It plays a pivotal role in connecting the country’s major economic centers, including Hanoi, Ho Chi Minh City, Da Nang, and Can Tho, facilitating the movement of goods and people across the nation.

The highway’s strategic importance cannot be overstated. It is a vital component of the North-South economic corridor, essential for national defense, economic development, and social integration. Historically, National Highway 1 has undergone numerous upgrades and expansions to keep pace with Vietnam’s rapidly growing economy and increasing transportation demands. However, many sections, particularly those south of Hanoi, have long been characterized by two-lane carriageways, leading to chronic congestion, reduced travel speeds, and increased accident rates, especially during peak hours and holidays.

The current upgrade project directly addresses these long-standing issues, particularly for the southern sections of the highway. The focus on the Nam Dinh to Vinh Long corridor signifies a strategic prioritization of the southern economic region, which is experiencing significant industrial and agricultural growth. Enhancing this stretch of National Highway 1 is expected to unlock further economic potential by reducing logistics costs and improving the efficiency of the supply chain.

Broader Implications and Economic Impact

The upgrade of National Highway 1 is anticipated to have a far-reaching impact on Vietnam’s economic landscape. By increasing the capacity and efficiency of this critical transport artery, the project will:

• Boost Economic Growth: Reduced transportation costs and improved transit times will make Vietnamese businesses more competitive, encouraging investment and trade. It will facilitate the movement of agricultural products from fertile southern regions to markets nationwide and internationally, and streamline the import of raw materials for manufacturing.
• Enhance Regional Connectivity: The improved highway will better connect provinces, fostering greater economic integration and reducing regional disparities. This will be particularly beneficial for the eight provinces directly involved in the upgrade, stimulating local economies and creating employment opportunities.
• Improve Road Safety: Modern, wider highways with better design standards are inherently safer. The reduction in traffic congestion and the implementation of higher design speeds are expected to lead to a decrease in accidents.
• Support Tourism: Enhanced accessibility to various tourist destinations along the route will likely boost the tourism sector, further contributing to economic development.
• Strengthen National Infrastructure: The project represents a significant investment in Vietnam’s national infrastructure, demonstrating the government’s commitment to modernizing its transportation network and supporting sustainable development.

The completion of these upgrades will ensure that National Highway 1 meets its planned capacity as a modern, efficient, and safe corridor, significantly boosting the operational efficiency of the North-South transport corridor. This initiative is a testament to Vietnam’s forward-looking approach to infrastructure development, aiming to lay the groundwork for sustained economic prosperity and improved quality of life for its citizens. The project’s success will be a critical factor in Vietnam’s continued trajectory as a significant player in the regional and global economy. The strategic expansion of this vital highway network is a clear indication of the government’s focus on building robust infrastructure to support its long-term development goals.
