A newly built span in southwest China—the Hongqi Bridge in Barkam (Ma’erkang), Sichuan—partially collapsed just months after opening. Dramatic videos shared online show a long section giving way in seconds, sending dust into the mountain valley. Thankfully, no casualties were reported because officials closed the bridge the night before after spotting cracks and slope movement near the site.
The Heading
- Where: Barkam, Sichuan province, along National Highway 317 toward Tibet.
- What: A landslide undermined the approach bridge and roadbed, causing a major section to collapse.
- When: Authorities shut the bridge on Monday, Nov 10 local time; collapse followed on Tuesday, Nov 11.
- Why no injuries: Police blocked traffic after engineers noted cracks and unstable slopes.
How the Hongqi Bridge collapse unfolded
Local officials first noticed terrain shifts and cracking around the bridge and nearby roadway. With risk rising, they closed the crossing and rerouted vehicles. On Tuesday, the mountainside failed, triggering landslides that knocked out the approach span and damaged the adjoining road embankment. Footage from the scene matches that sequence.
Why a new bridge failed so quickly
Early reporting points to geology rather than a sudden mid-span structural break: the slope above the bridge gave way, undercutting foundations and the roadbed. In high, wet, or fractured terrain, even brand-new infrastructure can be vulnerable if the ground beneath it moves. China’s rapid build-out in mountainous regions has faced similar risks before, which is why geotechnical monitoring (for slope creep, water pressure, and subsurface movement) is crucial.
About the Hongqi Bridge
Local and state media described the Hongqi Bridge as roughly 758 meters (≈2,487 ft) long, built as part of a strategic route linking Sichuan to Tibet. It reportedly opened earlier in 2025 after a fast construction schedule. Some outlets note the builder as Sichuan Road & Bridge Group. Those details help explain the attention: this corridor is a major lifeline for people and freight in western China.
What officials are doing now
- Investigation & monitoring: Authorities are assessing slope stability, clearing debris, and reviewing build and maintenance records.
- Traffic management: National Highway 317 traffic has been diverted while teams assess detours and temporary works.
- Safety messaging: Local government emphasized that early closure prevented injuries, and warned the public to avoid the site.
Why this matters beyond Sichuan
- Engineering lessons: The incident spotlights the geotechnical hazards of mountain infrastructure and the need for continuous monitoring even after opening.
- Economic impact: Highway closures in western China can disrupt supply chains and local travel across long distances.
- Public trust: Viral video of a brand-new bridge collapsing raises questions about design checks, slope protections, and maintenance regimes—issues that can influence policies far beyond one province. The Washington Post

FAQs on Hongqi Bridge
Was anyone hurt?
No. The bridge had been closed the previous night, so there were no reported casualties.
What caused the failure?
Preliminary reports indicate a landslide/slope failure that undermined the approach span and roadbed rather than a sudden mid-span fracture.
How new was the bridge?
It reportedly opened earlier in 2025, making the collapse only months after commissioning.
Is this part of a bigger problem?
China has invested heavily in mountain highways and bridges; experts warn these regions need robust geotechnical design and long-term monitoring because slopes can change with weather and water.
