The Gangola–Lhuntse SNH improvement project (Package II, 12.86 km) involves upgrading the highway to enhance safety, traffic flow, and road durability. The works include earthworks, pavement rehabilitation, subgrade stabilization, drainage improvements, and utility coordination. Upon completion, the upgraded road will improve connectivity, reduce travel time, enhance safety, and support regional socio-economic development while maintaining environmental and safety standards.
The improvement of Gangola–Lhuntse SNH faces challenges such as uneven terrain, weak subgrade, and sections requiring pavement rehabilitation and stabilization. Adverse weather, particularly heavy rainfall, may delay construction and affect pavement quality. Limited access to construction materials, site logistics, and coordination with utilities can impact timelines. Traffic management along the operational highway, ensuring worker safety, and minimizing environmental and social impacts are additional challenges.
Challenges can be mitigated through proper site investigation, pavement rehabilitation, and subgrade stabilization. Scheduling construction during favorable weather, timely procurement of quality materials, and efficient logistics will maintain progress. Traffic management plans, utility coordination, and environmental protection measures—such as dust, noise, and erosion control—will minimize disruptions. Continuous supervision, monitoring, and quality assurance will ensure durable and timely completion.
