Floodwaters Wash Away Bridges, Disrupt Connectivity Across Arunachal Pradesh and Assam
Villages remain isolated after floods washed away bridges in Northeast.
Relentless monsoon rains continue to batter Arunachal Pradesh and Assam, triggering flash floods, landslides and widespread damage to roads, bridges and public infrastructure, leaving thousands of people stranded and disrupting transport across the Northeast. Authorities said at least four people have lost their lives in Arunachal Pradesh over the past week, while more than 45,500 people have been affected by floods in neighbouring Assam as the region grapples with one of the season's most severe spells of rainfall.
The situation remains particularly grim in Arunachal Pradesh, where 12 districts have reported extensive damage caused by continuous downpours. Flash floods and landslides have washed away stretches of highways, damaged bridges and cut off several remote villages, making it difficult for rescue teams and essential supplies to reach affected communities. Officials are monitoring the situation closely as heavy rainfall continues to hamper restoration work and increase the risk of further landslides in vulnerable hill areas.
A major rescue operation was conducted in Lower Dibang Valley district after four people became stranded on an island in the swollen Sisiri River near Dambuk. An Indian Air Force helicopter was deployed to evacuate the stranded individuals to safety as rising water levels made conventional rescue efforts impossible. Elsewhere in the district, continuous rainfall caused severe damage to the strategic Roing-Anini road, with multiple sections of the highway and several bridges washed away by flash floods. The road serves as a crucial transport link for remote areas, and its disruption has significantly affected connectivity and the movement of relief material.

In Anjaw district, rescue teams are continuing operations after an excavator operator was feared killed when a massive boulder crashed onto the machine during highway construction work near Sarti village on Sunday night. The incident underscores the dangers posed by unstable slopes during the monsoon season, with authorities warning that persistent rainfall has considerably heightened the risk of landslides across the state's mountainous terrain. Emergency personnel have been working in challenging conditions to search the affected area while ensuring the safety of rescue workers.
Flood conditions have also worsened in Assam, where overflowing rivers and incessant rainfall have inundated large stretches of agricultural land and residential areas. According to officials, more than 45,500 people have been affected across several districts, with floodwaters damaging homes, roads and public infrastructure. Local administrations have activated disaster response mechanisms, including relief camps and evacuation measures, to assist displaced residents. Authorities are also monitoring river levels closely as continued rainfall upstream threatens to aggravate the flood situation.
Disaster management agencies in both states have urged residents living in vulnerable areas to remain alert and follow evacuation advisories where necessary. Restoration of damaged roads and bridges is expected to take time because of ongoing rainfall and difficult terrain, while relief agencies continue to prioritise rescue operations, delivery of essential supplies and rehabilitation of affected communities. With the monsoon expected to remain active over the coming days, officials have warned that the flood and landslide situation could deteriorate further, particularly in low-lying and landslide-prone regions of Arunachal Pradesh and Assam.
