Detectives are investigating the death of a woman whose body was found Tuesday on the two-lane La. 182 bridge that crosses the Atchafalaya River connecting Berwick and Morgan City, officials said.

The body was discovered at around 4 a.m., St. Mary Parish Sheriff’s Office Spokesperson Traci Landry said. Authorities provided no information about the possible cause of death or whether foul play is suspected.

“Detectives are working to identify the woman and notify next of kin,” Landry said.

The death is under investigation pending the outcome of the police and coroner’s reports, Landry said.

The bridge, which sits upriver from the four-lane U.S. 90 bridge, was closed for three hours Tuesday morning for investigators and emergency personnel who responded.
