The Department of Construction of Khanh Hoa Province, central Vietnam, has recommended that the Provincial People's Committee include a tunnel project (through Cu Hin Mountain) in the public investment plan for the 2026–2030 period.
According to the report, the Provincial Management Board for Agricultural and Transport Project Investment has been designated as the primary investor for the project.
The total investment capital is estimated at approximately VND3.751 trillion (nearly $143 million), with implementation scheduled for 2026–2030.
The project will have a total length of 5.2 km, featuring a tunnel section of approximately 4.5 km. The route is set to begin at the intersection of Nguyen Tat Thanh Street in southern Nha Trang and terminate at Provincial Road DT.657I in Cam Lam Commune.
In terms of scale, the road will have an average cross-section width of 20 m. The tunnel itself is designed with two parallel tubes positioned roughly 30 m apart, with each tube measuring 8 m in width.
According to the Department of Construction, once completed and operational, the project will provide an additional transport link between Cam Ranh International Airport and Nha Trang, significantly shortening travel times.
Furthermore, the tunnel is expected to support the growth of local industry, tourism, and service sectors.
