HCMC – A proposed sea-crossing bridge linking Can Gio with Vung Tau in HCMC will span 14.06 kilometers, including a nearly-4-km undersea tunnel, under a revised design plan submitted by the project’s investor consortium.
The Can Gio–An Hung–Dien Thinh–Lam Vien consortium has proposed extending the undersea tunnel from 3.1 km to nearly 3.85 km, according to a document sent to the HCMC government and the city’s Department of Finance.
Under the revised design, the entire bridge length remains unchanged, connecting the Can Gio coastal urban area with the Sao Mai–Ben Dinh planned area in Vung Tau. However, the immersed tunnel, precast and submerged beneath the seabed, would be lengthened from 2.1 km to 3 km.
The bridge above the sea surface would also be extended by 200m to more than 8km, while approach roads at both ends would be shortened to around 1.9km. The adjustment is aimed at optimizing construction in complex seabed geological conditions.
The project is designed with six lanes for motor vehicles. The tunnel section would be 30.2 meters wide, while the bridge section would measure 26.25 meters across.
Total investment for the project is estimated at more than VND93 trillion, including over VND9.26 trillion in loan interest costs during construction. The investor consortium said it would mobilize the entire funding for site clearance and construction, while the State would make payments through land allocation and partial budget support under a build-transfer (BT) contract model.
The consortium has also requested a special mechanism allowing investor selection under exceptional procedures so that investment approval and contract signing can be completed in the second quarter of this year. Construction and land clearance are expected to begin in the third quarter of 2026, with the project slated for completion after three years of construction.
Once operational, the route is expected to cut travel time between the two sides. The project is also seen as a strategic transport link connecting the Can Gio coastal tourism area, Long Son Industrial Park, and the Cai Mep–Thi Vai deep-water port cluster, while easing congestion on National Highway 51.
