Description
Co Chien Bridge is a
cantilever bridge using
prestressed concrete. It is 1,599 meters long and 16 meters wide, with four lanes of traffic with posted speeds of 80 kph.
It crosses the Co Chien River connecting the Mo Cay Nam district of
Ben Tre province with the Cang Long district of
Tra Vinh Province Tra or TRA may refer to:

* Tra (gene), in ''Drosophila melanogaster'' encodes the protein female-specific protein transformer
* Tra gene, a transfer gene

along Vietnam's National Highway 60.
It 3.6 kilometers downstream from the Co Chien Ferry Terminal that it was designed to supplement.
The architecture of the Co Chien Bridge consists prestressed reinforced concrete as well as reinforced concrete, using a balanced cantilever main span structure. The structure consists of 24 simple 40-meter spans using
Super T girders.
History
In 2011, Co Chien Bridge was chosen one of the four key projects prioritized as part of a larger effort to develop transportation infrastructure in the Mekong Delta and one of the key bridges of Vietnam's National Highway 60 (alongside the Rach Mieu, Ham Luong, and Dai Ngai bridges).
It would be developed under the
Build-operate-transfer model with a budget of 3,798 trillion
VND.
Construction began in 2013.
In 2012, the bridge took a major pivot when it was decided to scrap plans for a
cable-stayed bridge and opt for cantilever bridge, making for a major shift in the construction calendar and budget.
The cantilever bridge was completed in 2015, after 21 months of construction and 15 months ahead of the schedule (not including work on the cable-stayed design) at a cost of 2.3 trillion VND(US$106.2 million)
Effect

, boosting tourism and land development.
Additional roads have been planned to feed into the bridge, which have stalled due to a dearth of sand for construction in the region.
By 2017, the increase in traffic has also seen an increase of potholes in the roads leading to the bridge.
