What is gradient road?

Gradient roads are roads that are constructed with steep inclines or gradients on them. The purpose of building such roads is mainly to overcome elevation changes that present challenges to transportation and to reduce travel time or distance. These roads are more common in mountainous areas or in places where the terrain is hilly or undulating.

Whilst gradient roads can make travel on high terrain easier, they can also present significant problems to drivers. The steep grades can be difficult to navigate and can place a lot of strain on vehicles, particularly those with smaller engines or heavy loads. In addition, they require specialized design and construction techniques to create a surface that is safe and able to cope with heavy traffic and bad weather conditions.

In order to regulate gradient roads, most countries have established regulations and standards for their construction. These regulations may take into account factors such as the maximum gradient allowed, the width of the road, and the curvature required to ensure safe navigation. The safety and maintenance of gradient roads is an important consideration due to the risks of accidents, landslides, erosion, and general wear and tear.
