Livingston Parish officials Friday night placed a curfew on all residents except essential personnel from midnight to 7 a.m. Saturday.

Parish leaders, including Sheriff Jason Ard and Parish President Layton Ricks, set the curfew because of the danger posed by icy weather conditions, Lori Steele, a Livingston Parish Sheriff’s Office spokeswoman, said in a news release.

Mark Harrell, director of the parish office of homeland security, joined Ard and Ricks in setting the curfew.

“While our emergency crews have been tirelessly working to make travel conditions as safe as possible, that is becoming increasingly difficult,” Steele said in the release. “The plan — at this point — is to keep our main corridors open.”

Those roads include Florida Boulevard and Magnolia Bridge Road, Steele said.

She said it seems unlikely that crew will be able to keep overpasses on Interstate 12 open throughout the night due to the icy road conditions.

“Our main goal is to get residents home safely,” Steele said. “We are strongly encouraging everyone to remain in place until this weather event is over.”
