Construction of roads causes interference in the environment, resulting in number of ecological changes. Site facilities associated with road structures, including drainage system of a lane, play a significant role among environmental impacts. It affects particular elements of the environment, causing changes in existing ecosystems, in terms of, among others, surface and groundwater, soil, landscape and lively nature.
