ANSWER THE MINISTER OF ROAD TRANSPORT AND HIGHWAYS (SHRI NITIN JAIRAM GADKARI) (a) to (f) The details of National Highways (NHs) damaged during the 2025 monsoon season due to landslides, flashfloods and cloudbursts in Himachal Pradesh along with status of restoration of traffic, status of temporary and permanent restoration works including status of sanction and the timeline for permanent restoration is annexed. The primary reasons for such damages include breach of embankments, landslides, slips, damages of protection work, culverts, etc. due to rainfall, floods, erosion, drainage / associated hydraulic conditions, etc. Government encourages the adoption of innovative technologies or methods to enhance the durability and reduce the maintenance requirements of NHs (depending upon factors such as rainfall, terrain type, soil category, etc.). Such technologies or methods include stabilization of subgrade, geosynthetic reinforced layer(s) in sub-base / base, concrete roads / white-topping, perpetual pavement, High performance bituminous mixes, modified bitumen / bituminous mixes, Fiber Reinforced Concrete, Cement Grouted Bituminous Mixes, etc. Automated and Intelligent Machine-Aided Construction has been adopted which ensures cloud-based maintenance records and quality work. Various initiatives taken for developing disaster resilient NHs infrastructure including NHs in Hilly States/Union Territories with specific focus on excavation / cutting / stabilization of slopes includes: -i. Memorandum of Understanding (MoU) signed with Tehri Hydro Development Corporation India Ltd (THDCIL) for specialized landslide treatment measures for the States of Uttarakhand and Arunachal Pradesh. ii. Decision taken in November, 2024 for implementation of cost-effective long term remedial measures of landslide prone areas in hilly regions as per Expert Committee Report. iii. Decision taken to henceforth ensure implementation of slope cutting and stabilization works in the first instance to be followed up by road construction works for NHs in Hilly/Mountainous terrain. Road works are to commence only after protection measures are completed section-wise. iv. Finalization of a comprehensive policy circular in November, 2025 for additional augmented and systematic remedial measures to address concerns regarding construction of NHs in Hilly Regions. v. MoU signed with Defence Geo-informatics Research Establishment (DGRE) for Technological collaboration of Geo-hazard mitigation measures on National Highways. vi. MoU signed with Geological Survey of India (GSI) on Geological investigation for tunnels and sharing of data for Geohazard Studies. vii. MoU signed by National Highways Infrastructure Development Corporation Limited (NHIDCL) with National Institute of Rock Mechanics (NIRM) for broad area of collaboration in geotechnical Investigation scrutiny for tunnel projects, road projects, review/ proof check of design and drawings of tunnel during DPR /construction stage, checking of adequacy of instrumentation and monitoring devices, tunnel safety audit, formulation of scientific investigation based on rock mechanics and rock engineering for work package, training to officials, etc.viii. MoU signed with NIRM for peer review of Detailed Project Report for Shillong – Silchar Greenfield high-speed corridor. Initiatives have also been taken through funding a research scheme to IIT Roorkee for Development of Guidelines for the Assessment of Hillslope Instability using Instrumentation & Real Time Monitoring; an MoU has also been signed separately for study of Interferometric Synthetic Aperture Radar (InSAR)-based landslide monitoring and early warning system along a 100-km stretch of the Chardham Pilgrimage Route, Uttarakhand. It is also planned to install Early Warning & alert System capable of detecting landslide, land sinking, water table movement and communicating the location and daily status of the rockfall area covered with Protection Meshes / Rockfall barriers in Parwanoo-Solan section of NH-5 in the State of Himachal Pradesh. Funds under NDRF and SDRF are not earmarked for restoration of NHs damaged due to disasters.ANNEXURE ANNEXURE REFERRED TO IN REPLY TO PART (a) TO (f) OF LOK SABHA UNSTARRED QUESTION NO. 1879 FOR ANSWER FOR 11.12.2025 ASKED BY SHRI ANURAG SINGH THAKUR REGARDING IMPACT OF MONSOON ON NHS IN HIMACHAL PRADESH.
