The development of climate-resilient road infrastructure in the Himalayan region continues to face challenges due to unstable slopes, difficult terrain and frequent natural disasters. The Union road transport and highways minister highlighted that multiple measures are being implemented using global best practices and advanced technologies. These include partnerships with institutions such as THDC India Limited, the Geological Survey of India and the National Institute of Rock Mechanics for landslide management, geological studies and tunnel safety. Real-time monitoring systems, early warning tools and improved survey techniques are also being integrated to strengthen long-term infrastructure safety in hilly regions.

The Union road transport and highways minister, while addressing a workshop on resilient national highway infrastructure in hilly terrain, stated that continuous efforts are being made to strengthen construction practices by adopting global best practices along with modern engineering technologies.
He noted that the government has entered into memorandums of understanding with THDC India Limited for specialised landslide treatment work in Uttarakhand and Arunachal Pradesh. In addition, collaboration with the Geological Survey of India has been established for geological investigations and data sharing, particularly for tunnel and corridor-based infrastructure projects.
Further cooperation with the National Institute of Rock Mechanics has been focused on geotechnical scrutiny, design validation, tunnel safety audits, instrumentation-based monitoring and capacity building to improve technical expertise in sensitive zones.
It was also informed that a policy-level decision has been taken to ensure slope stabilisation is given priority before the start of road construction in mountainous terrain. This approach is aimed at improving durability and reducing long-term risk to infrastructure and commuters.
Support is also being extended to the Indian Institute of Technology Roorkee for developing detailed guidelines on hillslope instability, with an emphasis on real-time monitoring systems to improve early detection of risks.
Separately, an agreement has been signed for the deployment of InSAR-based landslide monitoring systems along a 100-km stretch of the Char Dham route in Uttarakhand, aimed at strengthening early warning capabilities in one of the most sensitive pilgrimage corridors. The Char Dham project, which has been under phased development over recent years, has repeatedly required engineering interventions due to recurring slope failures and monsoon impacts.
Large-scale topographical surveys using LiDAR and UAV technologies are also being carried out. These are being integrated with landslide susceptibility mapping and historical data to improve the preparation of detailed project reports for future infrastructure development in hilly areas.
