A major landslide mitigation effort has begun in Kodari along the Arniko Highway, aiming to reduce long-standing risks to both infrastructure and nearby communities.
According to the Department of Roads, the project is designed to protect more than 250 households that have been facing escalating danger from a large, active landslide for nearly a decade. The site, located at the 113-kilometer section of the highway, has progressively worsened over the past 8–10 years, threatening to severely damage the road and surrounding settlements.
The initiative, led by the Charikot Road Division Office, involves an investment of approximately Rs 47 billion and is described as Nepal’s largest slope stabilization project. The work follows local protests during last year’s monsoon season, when residents blocked the highway demanding a long-term solution.
Officials say the project incorporates advanced engineering measures, including deep anchoring up to 30 meters, grouting, and construction of reinforced MSE walls to stabilize the terrain. Drainage systems will also be developed to manage water flow, which has been identified as a key factor accelerating soil movement.
Authorities have linked the landslide’s scale to erosion caused by the Bhotekoshi River, noting that extensive foundation work and structural reinforcements are required to halt further damage. Plans also include horizontal drilling and installation of drainage pipes, along with the construction of large wells to channel trapped water away from the slope.
The design has been prepared in consultation with senior geotechnical experts in Nepal, with the goal of completing major works before the upcoming monsoon season to prevent further deterioration.
Construction contractor TSN Construction has already mobilized equipment at the site. The company says the project presents significant engineering challenges but confirms that round-the-clock operations are underway with substantial local cooperation.
Despite progress, delays in administrative procedures have slowed the pace of work, according to the contractor. However, all available resources are expected to be deployed to ensure key sections are completed ahead of the rains if no further disruptions occur.
