Rasuwa Flood Leaves Trail of Destruction: Roads, Bridges and Hydropower Projects Swept Away

The full scale of destruction left by Wednesday’s sudden Bhote Koshi flood is becoming clearer as authorities and rescue teams reach parts of northern Nepal that were initially cut off.

The flood tore through communities along the Bhote Koshi and Trishuli river corridors, damaging or destroying homes, markets, roads, bridges, hydropower facilities and other critical infrastructure.

The worst destruction has been reported in Rasuwa, particularly around Timure, Rasuwagadhi and Syapru Besi, but the flood’s impact has extended downstream into Nuwakot and Dhading.

Officials are still assessing the damage, meaning the figures are expected to change as more affected areas become accessible.

A 42-kilometre road link to China damaged

One of the most significant infrastructure losses is the road connecting central Nepal to the Rasuwagadhi border crossing.

The Department of Roads said the entire 42-kilometre stretch between Betrawati in Nuwakot and Rasuwagadhi in Rasuwa has been damaged at multiple locations.

Several concrete bridges along the route were also swept away.

The road is a critical connection to Nepal’s northern border and an important route for trade with China. Its destruction has effectively disrupted access to the Rasuwagadhi crossing.

Authorities said they were still assessing the complete extent of damage, while information from another section between Syapru Besi and the border was also awaited.

The latest destruction is particularly significant because parts of this same corridor were still being upgraded after previous flood damage.

Bridges swept away

The flood’s force has destroyed or severely damaged bridges along the river system.

Bridges serving road connections, settlements and hydropower projects have been affected, leaving some communities isolated and making ground-based rescue operations difficult.

The destruction of bridges has also complicated efforts to bring heavy machinery and relief supplies into the worst-hit areas.

The exact number of damaged bridges is still being assessed, but the Department of Roads has confirmed that several concrete bridges on the 42-kilometre Betrawati–Rasuwagadhi route were washed away.

Timure market area devastated

Timure, near the Nepal-China border, suffered some of the most severe destruction.

The flood moved through the settlement with enormous quantities of water, mud and debris, damaging buildings and commercial areas.

Aerial assessments showed extensive destruction across the area, with sections of the settlement difficult to recognise after the flood.

The local helipad was also swept away.

That created an immediate problem for rescuers: a helicopter sent to Timure was unable to land because there was no longer a safe landing area. The pilot reported that much of the village was barely visible from the air.

Homes and settlements swept away

The destruction was not limited to public infrastructure.

Homes and other private buildings along the river were swept away or heavily damaged as the flood surged through settlements.

An aerial assessment from the affected corridor showed destruction extending from Rasuwagadhi toward Bidur in Nuwakot, with floodwaters reaching significantly above the normal river level in some areas.

Residents were forced onto higher ground, while some people remained stranded on rooftops awaiting evacuation.

Officials said the full number of damaged and destroyed homes was still being compiled.

Markets and businesses hit

Commercial areas located beside the river suffered extensive damage.

Markets in Timure and Syapru Besi were among the areas affected, with buildings, shops, vehicles and stored goods exposed to the flood.

The sudden nature of the event left little time for residents and businesses to move property to safety.
