Currently, contractors are speeding up the construction progress of Dong Viet Bridge, striving to open it to technical traffic in early September, nearly 4 months ahead of schedule (December 24, 2024).
Mr. Nguyen Dinh Thang - Deputy Commander of the Dong Viet Bridge Project Joint Venture said that at this time, the bridge and the approach road are being constructed on schedule. Contractors are focusing on constructing the railing system, completing the embankment, median strip, concrete pavement, and installing the lighting system.
On the Hai Duong side, the construction unit of the Dong Viet bridge approach road connecting to National Highway 37 is paving asphalt concrete, while carrying out drainage, tree planting, talus reinforcement, and traffic safety system construction including installation of signs, line painting, guardrail installation, and marker posts, etc.
The Dong Viet Bridge project started construction in June 2022 with a total investment of nearly VND 1,500 billion. The project is invested by the Bac Giang Provincial Management Board of Investment and Construction of Transport and Agricultural Works. This is the largest cable-stayed bridge in Bac Giang province, crossing the Thuong River to connect with Hai Duong province.
When completed, Dong Viet Bridge will help people travel conveniently and safely. The project is expected to promote the circulation of goods between Bac Giang and Hai Duong provinces, develop tourism, and create favorable conditions to attract investors to industrial parks and clusters in Bac Giang province.
Dong Viet Bridge is over 730m long, with a 22.5m wide bridge deck. The main bridge consists of 2 cable-stayed spans, one flat deck, and the approach bridge consists of 14 Super T spans.
Dong Viet Bridge is built on a permanent bridge scale using reinforced concrete and prestressed reinforced concrete structures.
The cable bundles are installed parallel to the construction of the cantilever box girder section with a distance of 9m/bundle. 24 cable bundles in 2 cable-stayed spans are the main load-bearing structure of Dong Viet Bridge.
Inside each cable-stayed structure there are many cables bundled together to ensure the bridge can safely withstand the designed load.
The approach road to the bridge on both sides is about 7.86km long, with a level II delta road scale, 22m base, 21.5m road surface.
