Hung Duc Bridge with a total investment of more than 1,200 billion VND on the North-South Expressway, Dien Chau - Bai Vot section, nearly 4.1 km long, crossing Lam River is under urgent construction, expected to close on March 10 and be completed in early May.

The project has a total of 31 road bridges, including 23 bridges on the main route and 8 direct overpasses. Hung Duc Bridge is nearly 4.1 km long, this is the longest bridge on the North-South Expressway, Dien Chau - Bai Vot section.

Hung Duc Bridge is designed to be 17.5 m wide, with 4 lanes, a hard median in the middle and a design speed of 80 km/h.

The bridge was started in May 2022 by a consortium of contractors Dai Hiep Company Limited, Thai Yen Investment and Construction Joint Stock Company, Hoa Hiep Company Limited and Cienco 4 Group Joint Stock Company.

According to Dan Viet reporters, construction units are currently concentrating maximum machinery and human resources on the Hung Duc bridge construction site to complete it in early May. The bridge has a large design and complex structure, so many workers must concentrate highly to work.

Workers are focusing on cleaning the bridge surface to prepare for the next steps.

Mr. Tran Dinh Phong (of Thai Yen Company) said: "Despite the hot sun and sweat, everyone always encouraged each other to work hard to ensure the project's progress."

Some workers use the shadows of large steel blocks to work.

According to the project company representative, the most difficult part of the construction of Hung Duc Bridge is the process of pouring concrete for the bridge abutments under the riverbed. Because Lam River has a deep bed and high water level. If the construction is not completed on schedule, the flood water from the river will greatly affect the construction.

Supplies, materials, machinery... are all transported by river. Currently, the contractor must mobilize modern machinery and large barges to serve the project in the best way.

Engineer Nguyen Quang Trung - Commander of Hung Duc Bridge project (Cienco 4 Group), said: "The unit in charge of construction from pier M0 to pier T13 has now completed the bridge deck and cast the cantilever from pier T1 to T13, and is casting the railing and median strip. Sections T15, T16 and T14 are completing the connection points, and can be closed in the next few days." Photo: PV

There are only 2 more connection points to complete, and they can be closed in the next few days.

The bridge box girder is designed with several points of descent to check the bridge's electrical lines during use.

The most difficult part is the construction of bored piles and piers in the middle of the river, which must be done quickly to overcome the flood. Each piers has 20 piles, more than 50 m deep. Currently, many bridge spans have been connected, the construction volume has reached 92-95%.
