Guwahati : Incessant rainfall triggered multiple landslides along the Silchar-Haflong National Highway in Dima Hasao district on Wednesday, disrupting traffic and underscoring the fragility of the ??? route ahead of the monsoon season.

Officials said the first landslide occurred at Dalaichung, between Jatinga and Harangajao, after continuous rainfall loosened soil from adjoining hillsides, sending debris onto the roadway. Vehicular movement was temporarily suspended before authorities cleared the stretch and restored traffic later in the afternoon.

However, fresh rainfall in the evening triggered another landslide at the same location. Falling trees further blocked the highway, once again halting traffic. Restoration work was launched with assistance from local residents.

The repeated disruptions come amid ongoing infrastructure upgrades on the corridor. A 25-km four-lane stretch between Jatinga and Harangajao is currently under construction as part of the Silchar-Saurashtra East-West Corridor project. However, work on two railway overbridges at Dalaichung remains incomplete, delaying full operationalisation.

Earlier, on April 14, the National Highways Authority of India (NHAI) had indicated that even partial opening of a two-lane section would not be possible before June due to pending overbridge construction.

Meanwhile, residents of Dalaichung village have reported damage to agricultural land, plantations and homes, attributing the losses to ongoing construction activities. Alleging lack of compensation from NHAI, locals have halted construction work since Tuesday.

Authorities said efforts are ongoing to restore normal traffic flow, but recurring landslides have heightened concerns over commuter safety and preparedness along the route as the monsoon approaches.
