What is curb in road?

A curb is a raised edge that runs along the side of a road or sidewalk. It is typically made of concrete or stone, and is designed to keep pedestrians and vehicles separated. Curbs play an important role in managing stormwater runoff by directing water to storm drains instead of allowing it to flow freely across the pavement.

In urban areas, curbs often serve as a boundary between different types of transportation infrastructure, such as sidewalks and bike lanes. They also provide a physical barrier that protects pedestrians from traffic.

Curbs may be smooth or angled, and can be higher or lower in different parts of the road. They may also be painted or striped to indicate parking zones or other regulations. It is important for drivers to be aware of curbs and their height, as hitting them can cause damage to vehicles.

Overall, curbs play an important role in the safety and function of roads and sidewalks in urban areas.
