Highway crews spraying brine ahead of snowfall

The Kentucky Transportation Cabinet plans to pre-treat area highways in anticipation of light snow moving across the 12 counties of District 1 – including Livingston and Crittenden – over the next couple of days, and an additional opportunity for snow early next week.

Crews will initially concentrate on pre-treating bridges, overpasses, and other potential trouble spots such as hills and curves early Friday, then pre-treat additional areas through the day Friday as time allows.
Motorists should be alert for slow moving trucks and support vehicles on area highways as crews go about their work on Friday.

Pre-treating involves spraying brine on road surfaces. Brine is produced by pumping water through salt in a vat or generator. When brine solution is sprayed on the roadway the water component dries leaving behind a layer of fine powdered salt. That salt then remains on the driving surface available to be activated when winter precipitation first starts to fall.
