LACHEN, NORTH SIKKIM — In a race against time and the elements, the Indian Army has launched "Operation Him Setu" to rescue approximately 1,600 tourists stranded in the high-altitude region of Lachen. A massive landslide, triggered by incessant rainfall and sudden geological shifts, has severed the primary artery connecting North Sikkim to the rest of the state, leaving hundreds of travelers trapped behind a wall of debris and black ice.

The crisis escalated late Wednesday evening, April 8, 2026, when a major section of the road near the Taram Chu Bridge collapsed. This specific stretch had only recently been restored following previous monsoon damage, highlighting the extreme geological instability of the region. With the road effectively gone, a long queue of tourist vehicles was left immobilized between Lachen and the landslide zone. Troops from the Trishakti Corps were mobilized immediately, braving sub-zero temperatures and visibility-clogging mist to reach the stranded families.

Operation Him Setu—named for the "Snow Bridge" logistics required in such terrain—has focused on creating a human corridor. Recognizing that heavy machinery will take days to clear the massive boulders, engineers from the Border Road Organization (BRO) and Army units have constructed temporary footbridges and stabilized footpaths across the landslide face.

"Our priority is moving the vulnerable—children and the elderly—first," a senior military official stated from the site. "We are manually escorting tourists across the breach, while our technical teams work to stabilize the ground beneath us, which remains active and prone to secondary slides."

For the 1,600 individuals involved, the experience has been one of extreme hardship. The Army has converted transit camps into emergency shelters, providing hot meals, medical check-ups, and satellite phone access for tourists to contact worried relatives.

Many travelers reported being stuck in their vehicles for over 12 hours before help arrived. "The sound of the mountain coming down was terrifying," said one rescued tourist. "The Army arrived with blankets and tea when we thought we would be spending the night in the car with no heat."

The recurring nature of these disruptions has sparked a wider conversation regarding the sustainability of high-altitude tourism in the Eastern Himalayas. This latest incident comes just over a month after a similar washout, prompting calls for more sophisticated geological monitoring systems.

Strategic analysts suggest that "hard infrastructure" like asphalt roads may no longer be sufficient for the changing climate of the region. There is an increasing push for a "dynamic permit" model, where real-time geological sensors and weather data dictate travel permissions on a day-to-day basis.

As of Thursday afternoon, approximately 600 tourists have been successfully evacuated to Mangan, with the remaining 1,000 expected to be moved by nightfall if weather conditions hold. The Border Roads Organization is working in double shifts to create a temporary bypass, but they warn that the terrain remains highly saturated and unstable.
