Introduction

The Himachal Kisan Sabha has raised serious concerns regarding structural safety in Shimla, specifically demanding an independent investigation into recent geological issues linked to the under-construction twin-tube tunnel between Bhattakufar and Chalonthi (IGMC). The organization is particularly alarmed by the emergence of cracks and a large pothole that have appeared above the tunnel site, which they believe are a direct result of tunneling activities associated with the Parwanoo–Shimla four-lane project.

Concerns Raised by Kisan Sabha

Dr. Kuldeep Singh Tanwar, the state president of Kisan Sabha, emphasized the potential dangers posed to thousands of residents living in densely populated areas such as Cemetery, Shanti Vihar, and Chamiyana, which are situated directly above the tunnel alignment. The organization is calling for a thorough investigation by experts from either IIT Mandi or IIT Roorkee to assess the situation.

Recent Incidents Highlighting the Issue

On November 22, a significant incident occurred when a deep cavity formed suddenly, causing the tire of an HRTC bus to sink into it. This alarming event resulted in a student falling into the cavity, underscoring the severity of the situation. Following this incident, cracks have been reported in several structures, including:

  • Chamiyana Cooperative Society building
  • Pickup Union office
  • Multiple residential homes

According to Dr. Tanwar, these cracks indicate a possible impact of underground excavation on surface structures, raising concerns about the stability of the area.

Call for Independent Investigation

The Kisan Sabha has made a formal request for a third-party study by experts and scientists from reputable national institutes. They are seeking to determine whether the tunneling, blasting, or excavation activities have destabilized the hill mass. Dr. Tanwar stated, “Only an independent assessment by institutions like IIT Mandi or IIT Roorkee can provide a credible, scientifically grounded explanation for the developing cracks and subsidence.”

Government Response and Demands

In light of these developments, the Kisan Sabha has urged the state government to halt construction activities until the independent study is completed and its findings are made public. Dr. Tanwar expressed that negligence in tunnel construction could jeopardize entire settlements located above the tunnel alignment, emphasizing the need for transparency throughout the construction process.

Future Actions by Kisan Sabha

The Kisan Sabha has indicated that they will escalate their agitation efforts, especially if the government does not initiate a neutral scientific investigation promptly. The organization plans to rally support from affected residents to ensure their voices are heard and to advocate for the safety of their communities.

Conclusion

The situation surrounding the Shimla four-lane tunnel project highlights the complex relationship between infrastructure development and community safety. As the Kisan Sabha pushes for an independent investigation, the outcomes could have significant implications for both the residents of Shimla and the future of similar construction projects in the region.
