One person is still unaccounted for following multiple construction workers being thrown into the water Wednesday after scaffolding collapsed at the Loop Parkway Bridge, according to state police.

Authorities said about eight contracted workers were performing construction work on the bridge when the scaffolding gave way, sending them into the water.

Troopers said workers suffered injuries of varying severity and that one worker is unaccounted and another was undergoing CPR.

State police have an underwater recovery team on scene.

Police said the water emergency was reported around noon.
