India handed over the first consignment of components for a 70-metre Bailey bridge to Nepal's Road Division at Hetauda on 12 September 2026.
The bridge is meant to restore connectivity at Betrawati in Nuwakot district, cut off by the flash floods of 26 August 2026 in the Bhote Koshi-Trishuli valley.
Most of Nepal's existing Bailey inventory consists of shorter spans, too short for the wider gaps the floods carved out.
The bridge is part of an Indian relief effort of more than 130 tonnes of material flown in on at least eight Indian Air Force aircraft since 26 August.
A glacier collapse and landslide in the Langtang area set off flash floods down the Bhote Koshi-Trishuli valley; India's first C-130J relief flight leaves the same evening with 10 tonnes
A C-17 delivers 37.5 tonnes of tents, blankets, hygiene kits, solar lamps, dewatering pumps, kitchen sets, generators, medicines and food
India's eighth relief aircraft carries 35 tonnes, including NDRF and forensic equipment and replenishment for Indian Army teams
First consignment of the 70-metre Bailey bridge handed over at Hetauda for installation at Betrawati
A portable, prefabricated modular steel truss bridge developed in Britain in 1940-41 for wartime use. Its panels are light enough to be carried by truck and lifted by hand, so a span can be built without cranes or special tools, yet carry tanks.
Simple Analogy: A steel Meccano set for rivers - standard panels bolted into whatever span the gap needs.

The Bhote Koshi rises across the border in Tibet, enters Nepal through the Rasuwagadhi crossing area and becomes the Trishuli, which flows south-west past Betrawati in Nuwakot district before joining the Gandaki system. Hetauda, where the components were handed over, lies south of Kathmandu in Makawanpur district. Langtang National Park, where the glacier collapsed, sits along Nepal's northern border with Tibet.
