Severe Weather Causes Landslides on National Highway 315(A)

Jorhat, June 24: Continuous rainfall has led to several landslides along National Highway 315(A), raising concerns about potential disruptions in road access between Assam and Arunachal Pradesh.

Three landslide incidents have been reported along the highway that connects Joypur in Assam's Dibrugarh district to Deomali and Khonsa in Arunachal Pradesh's Tirap district.

This particular stretch, which traverses Dehing Patkai National Park, underwent widening and reconstruction in recent years.

However, the persistent rainfall over the past week has compromised the stability of the hill slopes, resulting in sections of the road collapsing into deep gorges at three critical points near the Kathalguri Beat Office within the Joypur Forest Division.

One of the landslide-affected areas is situated near a particularly dangerous U-turn on the highway.

Consequently, nearly half of the roadway has collapsed in certain areas, significantly narrowing the path and posing increased risks for travelers.

"The continuous rain over the past week has caused landslides along the Joypur-Deomali highway. The situation is quite perilous. If the rain persists, larger portions of the road could collapse," remarked a commuter.

Currently, while vehicle movement is still possible, authorities have implemented traffic restrictions from 6 pm to 6 am as a safety precaution.

This highway is crucial for residents of Khonsa, Deomali, Namsang, and other regions in Tirap district, who rely on Assam for access to markets, healthcare, and essential services.

Every day, hundreds of commuters travel this route to reach Dibrugarh and Tinsukia via Joypur and Naharkatia.

Although the National Highways Authority has set up safety barricades along the affected areas, there are ongoing concerns that further erosion could completely disrupt road connectivity between Dibrugarh in Assam and Tirap in Arunachal Pradesh.

This situation arises amid a broader weather alert for the region.

Earlier today, the Assam government issued a heightened alert due to extremely heavy rainfall and flash floods in Arunachal Pradesh's Lower Subansiri district.

Authorities have cautioned about a potential rise in river levels across several downstream districts in Assam over the next 24 to 48 hours.

Teams from the State Disaster Response Force (SDRF), National Disaster Response Force (NDRF), and other emergency response units are on standby for deployment if conditions worsen.
