Phuoc An Bridge, costing 4,900 billion VND, has the longest main span in Southeast Asia.

According to the reporter of Construction Newspaper, by the end of May, Phuoc An Bridge, which has the longest main span in Southeast Asia, is gradually taking shape after nearly 2 years of construction. On the construction site, the towering bridge piers have firmly stood on the Thi Vai River connecting the two banks of Dong Nai and Ba Ria - Vung Tau.

Currently, workers are focusing on constructing the bridge piers, spans, and decks. Some locations are completing the foundation tower segments, digging, filling, and leveling… The construction scene is bustling from dawn to late at night, sometimes having to work continuously through the night to increase work output.

According to the Regional Traffic Project Management Board and the Agricultural Sector, this project is divided into 5 main packages, the overall progress is being well controlled, ensuring according to plan. In packages 38 and 39, workers are speeding up the installation of girders and construction of bridge towers. Up to now, many main bridge towers have reached the middle of the river. The total output of these two important packages has reached more than 52%.

In package 38 from the beginning of the route to pier T36-T37, the contractor has completed 100% of reinforced concrete piles, bored piles, retaining wall modules and completed the construction of 26 piers/piers. At the construction site, the bridge spans have gradually appeared with 11/37 SuperT spans installed and many bridge decks taking shape, the output reaching about 60%.

The viaduct spans from the approach road in Ba Ria - Vung Tau province to the main bridge have also been installed, workers continue to speed up the construction of the bridge deck, working day and night to complete the tasks in turn.

Package No. 39 of the main bridge over the river, which plays the most important role in the project, has also achieved a production output of over 47%. The two main pillars T38 and T39, tens of meters high, are completing the tower body segments in turn, of which pier T38 has reached 10/15 segments.

According to the Project Management Board, the contractor is mobilizing about 350 engineers, workers and many super-gravity cranes up to 350 tons, 250 tons, and various types of tower cranes for construction. This bridge has a total length of nearly 4.4km, with the main bridge section being over 3.5km long, connecting from Phu My (Ba Ria - Vung Tau) to Nhon Trach district (Dong Nai) with the starting point connecting to the Cai Mep - Thi Vai inter-port route (Ba Ria - Vung Tau province) and the end point connecting to the route to Phuoc An port (Nhon Trach district).

The distance between the two main pillars of Phuoc An bridge is up to 250m, the largest in Southeast Asia to date. The project started construction in June 2023 with a total investment of nearly 4,900 billion VND and is expected to be completed in 2027. Of which, the central government will support 2,000 billion VND and the rest is from the budget of Ba Ria - Vung Tau province.

Phuoc An bridge has a main pillar with a navigation clearance of up to 55m, designed with a cable-stayed structure, using load-bearing steel to create solidity. Up to now, together with Binh Khanh - Phuoc Khanh bridge on Ben Luc - Long Thanh expressway, it has the highest clearance in the country. Allowing ships with a tonnage of up to 30,000 tons to travel without any obstacles or difficulties.

When completed, the bridge will connect Cai Mep - Thi Vai port area with Ben Luc - Long Thanh expressway and Ho Chi Minh City - Long Thanh - Dau Giay expressway (shortening the distance of transporting goods to the Southwest by nearly 30km). At the same time, Phuoc An bridge also helps reduce the load on Highway 51, which has been overloaded for many years, connecting the entire group of seaports No. 4, the largest group of seaports in Vietnam, with the Southeast region. The bridge creates a synchronous traffic system, helping to transport goods in the region faster and more conveniently.

With experience and expertise in the field of infrastructure construction, especially technical solutions for weak soil and road and bridge structures, Okasan Livic Vietnam can provide suitable solutions for the Phuoc An Bridge project. The application of lightweight EPS materials and foundation reinforcement solutions can help increase durability and minimize risks for the project.
