From the Louisiana State Police – With the rise of temperatures above freezing and the work of the Louisiana Department of Transportation, our travel conditions have improved. However, much of Louisiana will see the potential of a deep freeze again later this evening and into tonight. The drop in temperature will lead to the potential of “black ice” forming on our highways. Black ice is hard to detect as the ice tends to blend in on the roadway surface. All parts of the roadway are subject to forming black ice; however, it is most commonly found on bridges, overpasses, and roadways beneath overpasses.
