In July 2026, extreme monsoon rainfall superimposed with alpine glacial meltwater triggered successive severe landslides and debris flows in Kaghan Valley, Mansehra District, Khyber Pakhtunkhwa Province, Pakistan. According to local disaster monitoring statistics, the continuous torrential rain caused over 30 major slope collapses and debris flow outbreaks across the valley. The core traffic corridor, Balakot-Naran section of the Mansehra-Naran-Jalkhad highway, was fully blocked more than 8 times within one month, with cumulative traffic suspension exceeding 120 hours. A large volume of rock and mud completely covered road surfaces, leaving over 10,000 local residents and tourists trapped in the isolated mountain valley, facing shortages of daily supplies and medical resources.
The violent debris flows carrying huge boulders and uprooted trees surged into the Kunhar River, causing severe river silting and multiple temporary barrier dams. Several tributary estuary villages were severely impacted, with dozens of low-rise residential buildings buried by silt and rock debris. Most local small masonry bridges and low-standard concrete bridges suffered foundation scouring, structural deformation or partial collapse, completely cutting off regional traffic lifelines. The disaster exposed the extreme vulnerability of traditional infrastructure to mountain flood and geological hazards.
Kaghan Valley features steep alpine terrain, fragmented rock mass and highly saturated soil during the monsoon season, making it extremely prone to secondary geological disasters. Located in a medium-to-high seismic zone, the valley has a ground acceleration of 0.20–0.25g, posing strict seismic resistance requirements for infrastructure. Additionally, drastic day-night temperature differences and frequent flash floods with floating wood and rock impacts bring dual challenges of structural durability and impact resistance to bridge facilities.
EVERCROSS BRIDGE TECHNOLOGY (SHANGHAI) CO., LTD. is a professional steel bridge export enterprise with rich global production and delivery experience. All our products comply with international authoritative design standards such as AASHTO LRFD, and fully adapt to Pakistan’s local disaster prevention and design specifications, providing targeted modular steel bridge solutions for Kaghan Valley’s post-disaster reconstruction.
To adapt to Kaghan Valley’s extreme working conditions, our bridges adopt customized parameter design. In terms of hydrological resistance, all structures are designed based on 100-year return period flash flood standards, with additional verification of accidental loads from debris flow and floating wood impact. The local scouring depth of bridge piers and abutments is calculated with conservative parameters, and gabion bottom protection is equipped as standard to effectively resist riverbed scouring and stabilize foundation structures. For seismic performance, our bridges strictly follow Pakistan’s PS-02 seismic code to adapt to the local 0.20–0.25g ground acceleration, ensuring structural safety against aftershocks and geological vibrations.
Our standardized modular steel bridges have prominent advantages in post-disaster emergency repair. Firstly, all components are prefabricated in factories, enabling rapid on-site bolt assembly without complex concrete curing, which can restore traffic in a few days, far faster than traditional concrete bridges. Secondly, the structure can reuse remaining original abutments after professional bearing capacity and scouring risk recheck, saving reconstruction time and cost. Thirdly, all steel components adopt hot-dip galvanizing anti-corrosion treatment, adapting to the large temperature difference environment of mountainous areas and long-term outdoor erosion. Most importantly, the bridges are fully detachable and reusable, which can be disassembled and reconstructed for subsequent flood and debris flow disaster rescue, realizing cyclic utilization of emergency resources.
In addition to conventional emergency modular steel bridges, EVERCROSS supports diversified scene matching. We can provide large-span steel truss bridges for wide river sections and long-distance traffic corridors in the valley, solving the crossing problem of wide-span Kunhar River barrier sections. Meanwhile, customized modular steel footbridges are available for village branch roads and pedestrian passages, ensuring basic travel and rescue passage for isolated mountain villages. All products have passed CE, NATO, CIDB and other international certifications, with stable quality and strong global adaptability.
A1: Yes. Our bridges strictly comply with Pakistan PS-02 seismic code (0.20–0.25g ground acceleration) and 100-year flood design standards, with professional verification for debris flow and floating impact loads, fully matching local geographic and disaster characteristics.
A2: Yes. Our professional technical team will conduct on-site detection and recheck of abutment scouring degree and bearing capacity. Qualified original abutments can be directly reused to shorten construction period and reduce engineering costs.
A3: All modular components are prefabricated. Routine medium-span bridges can be assembled and opened to traffic within 3–7 days, realizing ultra-fast emergency traffic restoration, much more efficient than traditional concrete bridges.
A4: We adopt full hot-dip galvanizing anti-corrosion technology for all steel structures, matched with standard gabion bottom protection. It can resist mountain temperature difference erosion, river scouring and debris impact, with a long service life suitable for long-term mountain operation.
A5: We supply full-series products, including conventional modular emergency steel bridges, large-span steel truss bridges for main traffic lines, and lightweight modular steel footbridges for village pedestrian passages, covering all post-disaster traffic restoration scenarios.
A6: All products comply with AASHTO LRFD international design standards, and own CE, NATO, CIDB, PVoC and other authoritative certifications, meeting the bidding requirements of international aid projects and local government engineering projects in Pakistan.
