What is the main purpose of road intake structure?

The main purpose of a road intake structure is to collect and divert surface water runoff from roads and surrounding areas to prevent flooding, erosion, and damage to the road infrastructure. It helps to control the flow of water, filter out debris and sediment, and direct the water to a suitable drainage system or watercourse. Additionally, road intake structures can help improve water quality by reducing pollutants and contaminants from entering water bodies.
