Salt Treatment Concerns
Commissioners in a mountain county say the NCDOT's salt brine is ruining their cars and causing potentially dangerous brake problems.
The NCDOT uses brine trucks to spray salt water on highways before snowstorms arrive. Engineers say the brine makes roads safer by blocking ice and snow from bonding to the pavement. But mechanics and auto part managers say the brine is making brake lines and suspension parts unreliable and dangerous on their customers' vehicles. They showed commissioners brake lines that had rusted and broken. They say the brine causes more rust problems than rock salt because it coats the undersides of cars and trucks and is difficult to clean.
Commissioners have asked the NCDOT to stop using the liquid in Mitchell County. But NCDOT maintenance engineers say the brine is made from rock salt, and is the same product. Engineers say they haven't received the Mitchell County commissioners' request. But engineers say they'll work with the commissioners about the brine concerns.
