Overview
- Local authorities in Maerkang said mountainside deformation triggered landslides that caused the approach bridge and roadbed to collapse into the river on Tuesday.
- Police had shut the 758‑metre bridge on Monday after detecting cracks on nearby slopes and roads and observing terrain shifts on an adjacent mountain.
- No injuries or fatalities were reported, with all vehicles evacuated and the collapse area cordoned off for monitoring.
- Emergency crews and technical teams have launched an investigation to determine whether geological forces, reservoir effects or design and construction issues played a role.
- The bridge, built earlier this year by Sichuan Road & Bridge Group on National Highway 317 near the Shuangjiangkou hydropower project, remains closed with traffic rerouted and no reopening timetable; widely shared videos of the collapse have been verified by news outlets.
