A culvert is a structure used to allow water to flow under a road, railway, or other infrastructure. It can also be used to divert water from one area to another. Culverts are usually made from concrete, metal, or other materials and come in different sizes depending on the amount of water they need to handle. They are commonly found in places where there is a stream or river that needs to be crossed, or where water needs to be managed for irrigation or flood control.
