## 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.
