Floodwaters swept away a 300-meter-long iron bridge over the Kemi River in Assam's Dhemaji district on Sunday, June 28, 2026 [1, 2].

The collapse of the bridge has severed the primary road link between the Kemi-Purana Jelom area and Jonai Sadar. This disruption isolates local residents from essential services and transport hubs during a period of severe weather.

The bridge was carried away by powerful currents resulting from heavy rainfall and intense riverbank erosion [3, 4]. The structure connected Kemi and Oyan within the Dhemaji district, serving as a critical piece of infrastructure for the region [1, 2].

Local authorities said the destruction of the bridge is part of a wider pattern of flood-related damage in the area. Related flood disruptions in the region have affected nearly 16,000 people [5]. The loss of the iron bridge further complicates rescue and relief efforts as villages remain cut off from the main administrative centers.

Infrastructure failure in the Kemi River basin highlights the ongoing vulnerability of the region to seasonal monsoon surges. The sudden loss of the 300-meter span [1] leaves residents of Kemi-Purana Jelom without a direct route to Jonai Sadar, forcing a reliance on alternative, often precarious, water-based transport.

The collapse of critical infrastructure during the monsoon season underscores the systemic risk posed by riverbank erosion in Assam. When primary transit points like the Kemi River bridge fail, it creates a cascade of logistical failures that hinder emergency response and exacerbate the isolation of rural populations, potentially increasing the humanitarian toll of seasonal flooding.
