Normally, villagers construct a simple bamboo bridge to cross, which is destroyed by the river each year. During the dry season with little water, villagers can wad across the river. When it comes to the rainy season, the river floods, so there are frequent tragedies and deaths resulting from pedestrians drowning.

The Need – Apart from approximately 2000 villagers needing to wad across the river for access to the county and beyond, approximately 300 students have to cross the river to go to school.
