A mountain road can be defined as one that crosses a land with a cross-slope of 25% or more. When the road follows a river path, the mountains with a cross slope of less than 25% can be divisions along the road. Even these sections are also called mountain roads. Therefore, setting up a hill road must consider the ground land
In the mountainous areas, there is a wide range of climatic conditions, difficult and dangerous terrains, topography and vast elevation areas. The area is largely populated and lacks the basic infrastructure facilities available in the plain terrain. Therefore, for the overall development of other regions, a strong stable and potential road should be present in the hilly areas.
