Four bodies have been recovered from under a collapsed bridge in Taiwan, rescuers said on Wednesday, as searches continued for two people still missing when the structure smashed onto fishing boats moored underneath.

The National Fire Agency said two bodies were retrieved in the waters near a boat stuck underneath the shattered bridge while the others were found near a badly damaged boat that was dragged out from under the structure on Tuesday.

“The search and rescue mission continues,” transport minister Lin Chia-lung told reporters, adding evidence was being collected to ascertain any culpability.

Dramatic CCTV footage captured the moment the 140-metre long single-arch bridge came crashing down in Nanfangao, on Taiwan’s east coast early on Tuesday morning.

In the video, a vertical cable at the centre of the bridge’s steel arch suddenly snaps.

The road then collapses into the water, crashing down on three fishing boats as a petrol tanker which nearly made it across also plunged into the water.

Twelve people were injured, including six Filipino and three Indonesian fishing workers, the Taiwanese driver of the petrol tanker, and two coastguard personnel.

The petrol tanker burst into flames at some point after it hit the water, sending a thick plume of black smoke into the air.

Prosecutors have launched a probe into the cause of the collapse.

The local landmark was completed in 1998 and spanned a small fishing port. It was featured in a number of TV dramas and commercials. (AFP)
