The flood of 26 August swept away roads and bridges along the Trishuli river corridor. The Galchi–Devighat–Trishuli arterial, which links northern Nepal toward the Rasuwagadhi border crossing, was cut off. According to Nepal's Department of Roads, the disaster damaged 69 km of road and 37 motorable bridges nationwide. Thirty-three bridges were fully destroyed. The first estimate for permanent reconstruction exceeds Rs 73 billion (about Rs 73.34 billion under the RDNA assessment).

Recovery is moving in two steps. First, temporary repairs reopen single-lane traffic. Then Bailey bridges are installed at the key breaks. By mid-October, the Galchi–Devighat–Trishuli section had been temporarily repaired and reopened. A 60-metre Acrow bridge at Devighat was erected by the Nepali Army in five days. A roughly 76-metre Bailey bridge is under way at Betrawati. At Trishuli Bazaar, flood scour widened the river from about 60 metres to more than 120 metres, and the bridge option is still under review.

One detail matters most. The Department of Roads holds only ten 50-metre-class Bailey bridges in stock. The destroyed sites mostly need spans above 70 metres. With stock insufficient, Bailey bridges are being sourced from China, India and the United States and installed at priority damaged sections. This shows what mountain recovery really rewards: not "can you build it," but "how close are the components to site, who can mobilise fast, and who can erect it themselves."

Why Bailey bridges are the backbone of mountain recovery

A Bailey bridge is a modular steel-truss bridge. Its core advantages are almost purpose-built for mountain recovery.

• Standardised panels, pin connections, no field welding. Ordinary labour with hand tools can assemble it. No specialist welders or heavy cranes are needed. Risk and variability stay low.
• Cantilever launch, no intermediate piers. The span clears the floodway without occupying it, so work continues even in flood season. Deep or soft riverbeds are crossed in a single span.
• Rapid deployment. Erection crews can be on site within 24–72 hours. The outage window shrinks from months to days.
• Flexible spans. The standard single span covers 12–60 metres, and the D-type reaches 91 metres. Fewer piers mean less foundation work in difficult terrain.

Nepal is a country of deep valleys. Cast-in-place bridges there mean long construction cycles and hard component transport. Modular steel bridges use prefabricated parts and rapid on-site assembly with no complex welding. They fit the rugged local environment almost exactly.

We have delivered in Nepal: from pilot to repeatable solution

EVERCROSS BRIDGE TECHNOLOGY (SHANGHAI) CO., LTD. has delivered its second modular steel bridge project in Nepal. The TSR3 project is a single-span HD200 reinforced Bailey bridge. It is 51.816 metres long and uses a three-row single-layer reinforced configuration. The clear carriageway is 4.2 metres. The design load is 40 tonnes. The entire steel structure is hot-dip galvanised to ISO 1461, resisting Nepal's humid mountain climate, frequent rainfall and complex geology.

Before TSR3, the company completed and put into service Nepal's first HD200 three-row single-layer reinforced steel bridge. Two successive projects build a solid field reference for local transport upgrades. They also mark a milestone: our Nepal business is shifting from single pilot projects to replicable, mature solutions. Two operational bridges are the most direct demonstration samples for local authorities and engineering clients.

Exporting to Nepal — more than a supplier

We are an integrated manufacturer and trader. Our production entity is Zhenjiang Great Wall Heavy Industry Technology Co., Ltd., established in 2005 within the same group. Annual capacity reaches 10,000 tonnes of bridge components. We have delivered more than 500 bridges across 30-plus countries on four continents. A Nepal order is not a trial product. It is a globally validated, mass-produced solution with dependable scheduling and delivery.

On-site capability matters more. We provide local crew training, on-site supervision and technology transfer. Our engineers travel to the project site to guide installation and train the client's crew to erect the bridge themselves. Future projects no longer depend on outside experts. For mountain jobs, that removes the "waiting for external specialists" cost entirely.

The production baseline also meets international benchmarks. Welding is certified by Bureau Veritas (BV) and executed to EN 1090-2 EXC3. Welders are qualified to EN ISO 9606-1. Structural design follows AASHTO LRFD, with deflection L/800 and one million fatigue cycles. Galvanizing follows ISO 1461. Third-party inspection is carried out by SGS, CCIC and CNAS. Management systems hold ISO 9001, ISO 14001 and ISO 45001. Loads are not forced into a fixed bridge type. They are designed to the client's actual axle load — from HL-93 or HS20-44 up to 50, 80 or 100 tonnes and beyond, anchored to local code.

FAQ

Q1: How fast can a Bailey bridge be erected?

Erection crews deploy within 24–72 hours. Regular projects are scheduled by span and quantity (10,000 tonnes annual capacity). Mountain recovery often restores single-lane traffic within days.

Q2: Can it carry heavy loads?

Yes. It is designed to your axle load — from HL-93 or HS20-44 up to 50, 80 or 100 tonnes and larger, anchored to local regulation. Mining and construction fleets are covered.

Q3: Is field welding required?

No. Pin connections and hand tools let trained ordinary labour erect the bridge. No specialist welders or heavy lifts are needed.

Q4: Will it rust in Nepal's humid mountains?

The full structure is hot-dip galvanised to ISO 1461, adapted to the corrosion class. With one million fatigue cycles, it needs no major maintenance under high-frequency traffic.

Q5: Do you have delivery experience in Nepal?

Yes. We have delivered and put into service two consecutive HD200 reinforced modular bridges in Nepal, including the TSR3 project (51.816-metre single span, 40-tonne class), with on-site engineer guidance and local crew training.

Q6: Are compliance documents complete?

Yes. BV certification, EN 1090-2 EXC3, SGS/CCIC/CNAS third-party inspection and the ISO triple system provide a complete submission package that clears owner, supervision and donor-project review.
