An arterial road is a major road that carries large amounts of traffic over long distances, connecting different areas or neighborhoods. These roads are designed to handle high volumes of vehicles and typically have multiple lanes in each direction. Arterial roads are key routes that provide access to smaller streets, local roads, or highways, helping to move traffic efficiently through cities, towns, or regions. They are usually found in urban or suburban areas and play a crucial role in the transportation network by linking various parts of a city or region.
