Le Bac Village in Thu Bon Commune lies in the middle of the river and is currently connected to National Highway 14H by a single concrete road that crosses a spillway.
Residents said the village is cut off by floods eight to 10 times a year, with rising river levels making the only access road dangerous or impassable.
When floodwaters reach the second warning level, the road can be submerged by three to four metres of water, isolating more than 1,500 residents from nearly 400 households, including over 400 students.
Nguyen Hat, 63, a lifelong resident, said students have been among those most affected during the rainy season, often having to travel by boat to attend school when weather and river conditions allow.
Some parents have had to carry rice across the river for children staying away from home so they can continue attending school until floodwaters recede.
Hat said the new bridge would make it much easier for villagers to travel to school, work and local markets.
Another resident, Ho Ky, 45, said the existing concrete road is usable mainly during dry weather as it becomes flooded with fast-flowing water during heavy rain.
The village also has nearly 200 hectares of farmland, making reliable transport links important for farming and trade.
Major components of the Le Bac Bridge, including the main structure, lighting, railings and approach roads, have been completed.
Nguyen The Duc, chairman of the Thu Bon Commune People's Committee, said the bridge and its approach roads were undergoing final work and would open this month.
