La. Department of Transportation & Development crews were salting the Grand Ecore Bridge around 8 a.m. Wednesday, Jan. 17. Salting icy roads and walkways lowers the freezing point of the water that forms ice which leads to melting and prevents falling snow or rain from being able to freeze. Bridges are especially susceptible to freezing since air is allowed to flow underneath the roadway.
Erin Buchanan, Public Information Officer for DOTD said, “Crews in the District have been been salting since rain began Monday night in preparation for that precipitation to turn into snow. Those efforts have been continual on bridges and overpasses as needed. Crews have been working in 12-hour shifts to monitor conditions and apply salt treatment. Approximately 454,000 pounds of salt have been applied in the Alexandria District since operations began.”
