Majority of economic activities depend in one or the other way on road transport. Constant efforts are there to improve the quality and safety of road transport by integrating new technologies, smart vehicles, efficient traffic signals, new road surfaces, etc. However, most of our roads pass through critical terrains prone to landslides and rockfalls making it unsafe for the commuters. The paper presents a case study of Rehabilitation / treatment of landslide mitigations at various locations of National Highway 58 at Chamoli district in the state of Uttarakhand, India. The engineering investigation, design and analysis considerations, selection criteria for the mitigation systems, drainage measures, construction and installation challenges, monitoring and maintenance adopted etc has been described in detail. The paper brings out the significance of Landslide susceptibility mapping along road corridors especially in the Indian Himalayas which will help the planners and decision makers in determining the severity of probable slope failure areas.
