Himachal PWD Studies NHAI's Landslide-Prevention Tech on Kalka-Solan Highway

A Himachal Pradesh PWD team conducted a two-day training session to study the National Highways Authority of India's advanced slope protection work on the Kalka-Solan four-lane highway. Officials learned about engineering techniques like slope anchoring, steel mesh, and hydroseeding used to prevent landslides and stabilize mountain roads. The training, attended by engineers from multiple zones, aimed to adopt these successful methods for state road maintenance. The visit follows a similar study by Uttarakhand PWD officials in December 2025, who also advocated for implementing this technology.

Himachal Pradesh PWD team studies NHAI's slope protection work on Kalka-Solan four-lane

Himachal PWD officials train with NHAI to study advanced slope protection techniques aimed at preventing landslides on mountain highways.

"This technology could prove effective in road maintenance and mountain stabilisation in the state. - Narendra Chaudhary"

Shimla, February 20

The Himachal Pradesh PWD team, impressed by NHAI's slope protection work, studied the ongoing slope protection work on the Kalka-Solan four-lane.

According to the release, the two-day training session was organised for the PWD officials. During this session, the PWD officials understood the importance of slope protection in the mountains and how it is performed. The team also learned about the materials and techniques used in slope protection.

On the first day, officers from the Shimla Zone attended the training session, while on the second day, officers from the Mandi, Kangra, and Hamirpur Zones participated in the training. During the training, NHAI provides the information to PWD officers on the importance and techniques of slope protection through site visits and presentations.

Assistant Engineer Sahil Rana, who arrived for training from the Shimla Zone, said that he had come to study the slope protection work being carried out by the NHAI. In the past few years, heavy rainfall has increased the problem of landslides in the mountains. To protect the mountains and keep traffic flow smooth, the NHAI is implementing slope protection measures, which have been very successful. The PWD team has arrived to study the technology behind this work.

Meanwhile, Kangra Zone Executive Engineer Narendra Chaudhary stated that NHAI has organised a training session on slope protection work, which is commendable. In a hilly state like Himachal, NHAI is using advanced technology to perform slope protection work, which has been very successful. This technology could prove effective in road maintenance and mountain stabilisation in the state.

Impressed by NHAI's work, in early December 2025, Uttarakhand PWD Secretary Dr. Pankaj Kumar Pandey, along with a team of Engineer-in-Chief, Chief Engineer, and other officials, visited ongoing NHAI projects in Himachal Pradesh.

During this visit, they studied mountain roads, slope protection, tunnels, and bridge construction. Impressed by NHAI's work, they advocated for the adoption of this technology in Uttarakhand.

Slope Protection is a process to prevent landslides in hilly and sloping terrains. It involves the use of various engineering and bio-engineering techniques to strengthen and stabilise vulnerable slopes. Commonly used methods include slope anchoring combined with steel mesh, jute matting, and hydroseeding to promote vegetation growth and long-term slope stability.

Finally some proactive steps! The monsoons every year are a nightmare for Himachal roads. Learning from NHAI's expertise is smart. But will the PWD have the budget and willpower to implement this on a large scale? That's the real question.

As an engineer from the Kangra zone mentioned in the article, I can confirm the session was very insightful. The combination of steel mesh and bio-engineering for long-term stability is something our state PWD needs to prioritize. Jai Himachal!

Good to see inter-departmental learning. But let's be honest, often these "study tours" become just formalities. I hope the PWD officials actually apply what they learned and we see tangible improvements on our state highways, not just reports.

Visiting from Canada and have driven in the Himalayas. The terrain is challenging. Using techniques like hydroseeding for vegetation is brilliant—it's sustainable and strengthens the slope naturally over time. More power to such initiatives!

Uttarakhand team visiting in Dec 2025? Is that a typo? Anyway, the tech sounds promising. Hope this knowledge sharing becomes a regular feature between central and state agencies. Our mountains need all the protection they can get.
