A bridge in China’s southwestern Sichuan Province collapsed just months after opening, following visible signs of geological instability in the surrounding terrain.

Local authorities in Maerkang city confirmed that a portion of the Hongqi bridge, which spans 758 meters along a national highway linking central China to Tibet, gave way Tuesday afternoon.

Why It Matters
The sudden collapse of a new structure has raised concerns about long-term construction standards, particularly in China’s western provinces, where major transportation projects often traverse unstable terrain.

Although there is no evidence yet of construction flaws in the Hongqi Bridge, the incident comes just months after another high-profile failure. In August, a railway bridge under construction in Qinghai province collapsed during a cable-tensioning operation, killing at least 12 workers and leaving four others missing.

Local officials said that worsening mountain conditions triggered landslides, which in turn caused the approach bridge and roadbed to collapse.

The first signs of trouble appeared on Monday, when slope deformation was detected on the right bank of the bridge section of the highway in Maerkang City. Local authorities immediately launched an emergency response. By 11 p.m., all stranded vehicles had been evacuated, and warning signs were placed at the site to restrict unauthorized entry, according to the local paper Sichuan Daily.

The Hongqi bridge had only recently been completed, according to promotional material released earlier this year by its contractor, Sichuan Road & Bridge Group. No injuries or fatalities were reported, according to Reuters.

However, these back-to-back incidents have raised broader concerns about China’s retreat from large-scale infrastructure investment. Once known for pouring trillions of dollars into roads, railways, and airports to fuel growth, Beijing has recently faced scrutiny over declining quality control and the construction of projects in geologically unstable regions.

Chinese authorities often describe such accidents as isolated events or the result of “natural disasters,” such as landslides or flooding. Yet construction safety experts and international observers continue to question the country’s regulatory oversight and the rapid pace of development in areas vulnerable to seismic or environmental risks.
