Work on the new Thi Cau Bridge linking Bac Ninh and Bac Giang provinces in northern Vietnam started Monday.
The current Thi Cau Bridge is used for both railway and cars. The new bridge is built to separate that traffic, and the old bridge will be for trains only.
It is one of the three new bridges to be built as part of a project to separate these kinds of traffic.
Currently Thi Cau is one of the 10 bridges used by both trains and other vehicles, which caused traffic jams and posed high traffic risks.
The new Thi Cau Bridge will be 30 meters from the existing one, aims to separate road and railway traffic to ensure traffic safety and prevent congestion, according to the Railway Management Board for Region 1.
The management board also started the reinforcement of the current bridge.
The new bridge will be 572 meters long and 16 meters wide, designed for traffic speeds of 60km/h. It is set for completion in late the first quarter of 2013. The total cost is VND466 billion, or some US$22.3 million.
