The highway is closed due to high water and flooding.The National Weather Service is warning of life-threatening flash flooding, and a flash flood watch is in effect in the area until 5:45 p.m. local time.The flooding is expected to be continuous, Iberville Parish Emergency Preparedness OEP Director Clint Moore told ABC News.The Louisiana Department of Transportation and Development was helping to reinstall the flood barriers, spokesperson Rodney Mallett told ABC News. It is unclear how long it will take to repair.Residents were advised to evacuate to a Red Cross shelter at the civic center in Plaquemine, a city in the parish.Over a dozen State Fire Marshal deputies were on the ground in the Bayou Pigeon area helping residents evacuate via boats and a high-water vehicle “as high water threatens homes,” the office said.Large animals needing to be evacuated from flooded areas could also be brought to a multi-use facility in Plaquemine.The flooding comes after the Baton Rouge area was inundated with more than 13 inches in under 24 hours earlier this week. In the days since, residents in parishes in the region have had to contend with flooded roads.The use of the artificial flood barriers, known as AquaDams, has been contentious in the Baton Rouge area, according to The Advocate, as some local officials have argued the inflatable dams pose a flood risk to homes in East Baton Rouge.
