Unpaved rural roads are a source of water and air pollution. If rural roads are unpaved, loose soil can be carried away from the roadway by water, wind, traffic, or snowmelt, causing soil erosion. More erosion can occur if there is a large amount of water runoff or if the road soil is poorly compacted. Most of the eroded soil ends up in streams and rivers, where it can collect and cause flooding, destroy aquatic habitat, and harm water quality. Unpaved roads in forests are also a major source of erosion from forested lands.

As traffic travels on unpaved roads, it grinds up the road’s dirt surface and creates coarse particulate matter and dust emissions. In rural agricultural areas, heavy agricultural equipment not only emits particulate matter when it is used on the farm, but also grinds up the soil surface of unpaved roads, causing more particulate matter pollution.

Safety concerns for drivers on rural roads include slippery surfaces, soft shoulders, no center line markings, and narrow road surfaces.
