Traffic is moving again on the Galchhi–Devighat–Trishuli section of the Rasuwagadhi corridor. Emergency repairs have reopened the road, and the Department of Roads is pushing to restore full access to the Nepal–China border point.

That is progress. It is not a solution. Two of the three priority crossings on this corridor still have no bridge. One needs a 76-metre span. At the other, the river has doubled in width. Until those gaps are closed with long-span modular steel bridges, the corridor stays in temporary mode — and every week in temporary mode has a price.

What the Flood Left Behind

On Bhadra 10 (26 August 2026), floods on the Trishuli river cut the main route between Kathmandu Valley and Rasuwagadhi. The Department of Roads reports 69 kilometres of road and 37 motorable bridges damaged or destroyed in a single event.

• 33 bridges were completely washed out. Bailey bridges were planned for immediate installation at Devighat, Betrawati and Trishuli Bazaar.
• Only one is complete: a 60-metre span at Devighat, installed by the Nepali Army in five days.
• Betrawati still needs 76 metres of span. Foundation work has started and materials are being moved in. Around it, roughly 4 kilometres of road were destroyed, 3.2 kilometres cleared, and the last 800 metres rebuilt through steep, unstable ground.
• Trishuli Bazaar is harder still. The river was 60 metres wide before the flood. It is now over 120 metres, and engineers are still deciding the span.

A 73-metre bailey bridge over the Phalakhu river restored the direct Nuwakot–Rasuwa link only after six weeks of severed connection.

The Cost of Waiting Is Measured in Billions

The post-flood damage assessment puts permanent reconstruction at NPR 73.34 billion — permanent works only, with no allowance for the daily cost of detours. For freight moving to and from Rasuwagadhi, a severed bridge means longer hill routes, lower axle limits and unpredictable transit. A temporary bridge is therefore not a cost. It is a way of stopping the loss while the permanent structure is designed, tendered and built.

The Real Shortage Is Long Spans, Not Bridges

The Department of Roads has stated the constraint clearly: it holds 10 bailey bridges of 50 metres in stock, while the damaged sites need more than 70 metres. That is why spans are being sourced from China, India, the United States and other markets on an emergency basis.

The requirement is not simply “a bridge”. It is a long single span, delivered as modules, moved on mountain roads, and assembled without heavy plant.

How Modular Steel Bailey Bridges Close the Gap

Our steel bailey bridges are built for this job. Here is what each design decision means for a road authority under time pressure.

Long single spans — 12–60 metres standard, up to 91 metres with the D-type. A 76-metre crossing can be spanned with no intermediate pier. That keeps the flood channel clear and removes the pier that scouring would attack first.

Cantilever launch, no intermediate pier, no field welding. All connections are pin-jointed and assembled with hand tools. Local crews can erect the bridge — no specialist welders, no heavy crane fleet on a landslide-prone approach.

Emergency deployment in 24–72 hours. An assembly team can be on site within three days of confirmation. Where six weeks of closure has just been measured in lost trade, days matter.

Load capacity designed to your axle load. Nominal classes include HL-93, HS20-44 and HS25-44, extendable to 50 t, 80 t, 100 t or higher and anchored to local axle-load regulations.

Deflection of L/800, fatigue tested at 1,000,000 cycles, calculated to AASHTO LRFD. Built to stay serviceable under thousands of daily load cycles, with hot-dip galvanizing to ISO 1461 for a monsoon climate.

Detachable and re-usable: 10,000 tonnes of annual capacity, 500+ bridges delivered in 30+ countries. When the permanent bridge opens, the modules can be recovered and moved to the next site — an asset concrete cannot provide.

Built to the Standards Your Tender Specifies

Specifications differ by market, and a supplier should meet the buyer’s documents. Our engineering team aligns design and fabrication documentation with the system named in the tender:

• US-practice specifications — AASHTO LRFD design, HL-93 / HS20-44 / HS25-44 load classes, ASTM galvanizing.
• European-practice specifications — EN 1090-2 EXC3 execution, welders qualified to EN ISO 9606-1, galvanizing to ISO 1461.
• Other systems, such as AS 5100, on request.

Behind that sits a plant that accepts third-party scrutiny: Bureau Veritas-certified welding, inspection through SGS, CCIC or CNAS, and management systems certified to ISO 9001, ISO 14001 and ISO 45001 — so certification files, inspection reports and load documentation arrive complete.

Proven in Nepal: A 51.816-Metre HD200 Three-Row Reinforced Bailey Bridge

This is not our first crossing in the region. We have successfully completed the on-site installation of one of the two customized HD200 three-row single-layer reinforced steel bridges in Nepal, marking another solid milestone in our overseas infrastructure layout in the South Asian market.

The project uses a high-performance HD200 three-row single-layer reinforced bailey bridge structure, tailored to Nepal’s complex mountainous terrain and harsh construction conditions:

• Single span: 51.816 metres
• Clear lane width: 4.2 metres
• Standard load capacity: 40 tonnes

The reinforced structural design improves the bridge’s stability, durability and traffic bearing capacity, meeting local daily cargo transport and passenger travel demand while adapting to long-term outdoor conditions in a mountain climate. Two units were customised for this package and the first has now been erected on site.

A Local Partner, Not Just a Supplier

Government buyers are rightly cautious about buying a bridge they cannot maintain or redeploy. Our delivery model includes local crew training, on-site supervision during erection and technical transfer, so the department’s own people learn to assemble, inspect and later relocate the structure.

Questions Road Authorities Ask Us, Answered

Q: We need a 76-metre crossing and the river may widen further. Can you deliver that as a single span? 

A: Yes. Our standard single-span range is 12–60 metres, and the D-type reinforced configuration reaches 91 metres in a single span (in-house type test report 2017-QL-025). That covers a 76-metre crossing and gives span flexibility for a channel that has already moved from 60 to 120 metres.

Q: How fast can a bridge be on site and erected? 

A: Emergency assembly teams can be deployed within 24–72 hours of confirmation, using cantilever launch, pin-jointed modules and hand tools — no special plant required.

Q: What load can the bridge carry, and do we need field welding?

 A: Capacity is designed to your traffic and regulatory axle loads — nominal HL-93, HS20-44 and HS25-44 classes, extendable to 50 t, 80 t, 100 t or more. The Nepal HD200 project was specified at 40 tonnes with a 4.2-metre clear carriageway. No field welding is required: all connections are pin-jointed.

Q: What compliance documentation comes with the bridge? 

A: Bureau Veritas-certified welding, execution aligned to EN 1090-2 EXC3, welders qualified to EN ISO 9606-1, galvanizing to ISO 1461, third-party inspection through SGS, CCIC or CNAS, and ISO 9001 / ISO 14001 / ISO 45001 management systems. Design calculations can be issued to AASHTO LRFD or the standard your tender names.
