Culvert is a buried structure, similar to bridges, consisting of single or multi-span construction with a minimum length of 3m for each span. Two horizontal slabs are cast monolithically with two or more vertical side walls, with a maximum span of 6m.
A culvert is a section next to a road, or a cut in the area underneath it, and its sole purpose is to allow water to drain. If culverts are not used by roads, water would end up pooling, creating a hazardous problem that people would have a hard time avoiding.
