Chinese authorities say two people have been confirmed dead after a bridge under renovation collapsed in China's southern island province of Hainan.

Chinese media reports say the Taiyanghe Bridge near the city of Wanning collapsed late Monday. A local official said two workers were under the bridge checking the renovation progress when it crumbled. He said one of the two died on the way to a hospital, and the other was found dead under the rubble.

The official said rescuers were still trying to confirm whether more workers were buried under the rubble.

The cause of the accident is under investigation.
