A recently opened 758-metre-long bridge in China’s southwestern Sichuan province collapsed on Tuesday, with no casualties reported.

The Hongqi bridge, located on a national highway linking the country’s heartland with Tibet, had only been completed earlier this year.

Safety concerns prompted the closure, as conditions on the mountainside worsened significantly by Tuesday afternoon.

Landslides triggered by the deteriorating conditions ultimately led to the collapse of the approach bridge and its roadbed.
