1. Motor Roads
In the hilly regions, motor roads are the main communication system. These roads are suitable for all types of traffic. Hence, this road can be used by all sorts of traffic. These roads can have one or more lane width.
2. Bridle Paths
Bridle paths are the main roads for pedestrian traffic, these paths are used by pedestrians and Mule traffic. Bridle paths serve as feeder roads to motor roads. General, they are 2 m to 3 m in length and 1 in 8 to 1 in 10 in slope. If these roads are to be used by a jeep, the width should be kept between 2.45m to 3.65m.
3. Village Paths
The village paths act as a connector between villages and other important areas in hilly regions. These are usually 1m to 1.2 m wide and may have a slope of more than 45 degrees. For these types of paths, the recommended value of the ruling gradient is 1 in 7.5 and the limiting gradient is 1 in 5.
As per Border Roads Organization, the hill roads are classified as
