The People's Committee of the northern mountainous province of Dien Bien has formally submitted a proposal to the Prime Minister and the Ministry of Construction (MoC), seeking investment for the Moc Chau – Son La – Dien Bien – Tay Trang Border Gate expressway section.

This initiative aims to complete the Hanoi – Hoa Binh – Son La – Dien Bien Expressway in accordance with the approved master plan.

The Hanoi – Hoa Binh – Son La – Dien Bien Expressway project, spanning approximately 450 km, will be implemented in phases. The Hanoi – Moc Chau (in Sơn La province) section (119 km) is currently under construction, with completion expected by 2028. However, the Moc Chau – Son La – Dien Bien – Tay Trang Border Gate section (305 km) has yet to receive investment funding.

According to the adjusted master plan, the Son La City – Tay Trang Border Gate section (200 km, 4 lanes wide) has been designated a priority investment project for completion before 2030.

Previously, the MoC submitted a report to the Ministry of Finance, outlining progress on the 2021-2025 medium-term public investment plan and detailing funding priorities for the 2026-2030 period. The proposal included the Moc Chau – Son La – Dien Bien – Tay Trang Border Gate section as a strategic infrastructure project requiring priority investment.

The Provincial People's Committee emphasized that this expressway aligns with the national master plan and is crucial for boosting socio-economic development, enhancing national defense and security, and strengthening connectivity in the Northwest region of the country, particularly in Dien Bien province.
