This project is part of a larger development that includes the Ca Mau - Dat Mui expressway and the Hon Khoai dual-use port, which broke ground on 19/8. The main bridge will span 17.3 km, with a 0.87 km branch leading onto the island. The bridge deck will be 16.5 m wide.
The foundation will primarily consist of bored piles, with steel pipe piles used in deeper water. The bridge girders will be a combination of reinforced concrete and composite steel, with a 150 m steel arch span for the navigation channel. Military Engineering Command 12 (Ministry of National Defense) will construct the project. The total investment is over 25.7 trillion VND, and completion is expected by the end of 2028.

The bridge will connect to the over 80 km, four-lane Ca Mau - Dat Mui expressway, which also has two emergency lanes and a design speed of 100 km/h. This expressway has a budget of nearly 59 trillion VND and is also scheduled for completion in 2028.
In parallel, the Hon Khoai dual-use port is being built on the island. It will feature a 1,000 m long wharf, with a capacity of 20 million tons per year, capable of accommodating vessels up to 250,000 DWT. Upon completion, the port will expand to 686 ha and add container and liquid/gas terminals, handling vessels up to 150,000 DWT.
Upon completion, the bridge, port, and expressway will create a continuous north-south transport link to the southernmost point of Vietnam. This will boost the maritime economy and enhance national defense and security in the region. The bridge will be the longest sea-crossing bridge in Vietnam and the third longest in Southeast Asia.

Pham Thanh Ngai, Chairman of the Ca Mau People's Committee, stated that Ca Mau is the only province with three sides bordering the sea, possessing a vast maritime area and a strategic location in the heart of Southeast Asia. The Hon Khoai archipelago, located at the forefront and adjacent to international shipping lanes, has favorable natural conditions for developing a deep-water port.
Hon Khoai Island is approximately 4 km2, located 15 nautical miles (nearly 28 km) offshore. Its highest point is 318 m above sea level. Currently a military island, it has no civilian population.
