The national highways are always considered as the economic backbone of the country and have often assisted development work all along their routes. The National Highway (NH-1D) is the most strategic and the only all weather surface link between the two districts of Ladakh region (Kargil and Leh). The area under investigation experiences high vehicular traffic, particularly between March and August, as in the remaining months the Kargil and Leh districts?remain cutoff?from each other due to bad weather. In recent years, frequent occurrences of slope failures along the highway primarily affect the smooth functioning of the traffic movement which severely affects the life of the people of the area. Strategically, this road network is very important and plays a significant role in transportation and other activities. In order to ensure the stability of road network in the area, it becomes extremely important to understand the triggering mechanism of these failures. The present study made an attempt in this direction and the Slope Mass Rating (SMR) method has been used for slope stability analysis at different locations. The stability of the slopes was also assessed using kinematic analysis conjointly with SMR to identify the types of failure and its potential failure directions associated with each slope. The result obtained after calculating RMR from the selected facets ranges from 11 to 89 with lower values indicating presence of potentially unstable areas. Results have shown that in a total of 20 facets, 65.28% belong to wedge failure, 22.26%?belong to toppling failure and 12.45% belong to plane failure.
