A culvert is a structure that allows water to flow under a road, railway, or other obstruction. It is typically made of materials like concrete, metal, or plastic and is designed to manage water drainage and prevent flooding. Culverts can vary in size and shape, depending on the amount of water they need to handle and the specific location. Culverts are essential for maintaining the integrity of infrastructure and protecting the surrounding environment. They help direct water from streams, rivers, or drainage systems, ensuring that roads and properties remain safe and dry. Properly designed culverts can also support wildlife movement and reduce erosion.
