Overview
- Police shut the 758‑meter span on Monday after detecting cracks and terrain shifts, and officials report no casualties from Tuesday’s collapse.
- The failure destroyed the approach span and roadbed near Maerkang on National Highway G317, a key route linking Sichuan with Tibet.
- Construction had been completed earlier this year by Sichuan Road & Bridge Group, and the bridge had been open for only months.
- Dramatic videos shared on Chinese social media show the mountainside giving way and a section of the bridge plunging into the river.
- Emergency and inspection teams continue to secure the area and reroute traffic, with a technical investigation underway and no timeline for reopening; unverified claims about reservoir effects are being reviewed.
