Ice is threat on interstate bridges, overpasses

msprice@charlotteobserver.comMarch 17, 2014 

Beginning at 2 a.m. Tuesday , the N.C. Department of Transportation will mobilize five contract trucks to treat interstate bridges and overpasses in Mecklenburg and Cabarrus counties with a brine-calcium solution, as more frozen precipitation may create hazardous conditions on elevated surfaces.

Current weather forecasts show a 40 percent chance of freezing rain moving through the Charlotte area before 8 a.m. with less than a tenth of an inch accumulation. Icy patches could form in the early morning hours, so motorists should remain alert.

Temperatures should rise above freezing by 10 a.m. Engineers will monitor conditions and temperatures through the event’s duration, modifying plans as needed, officials said.

The brine-calcium solution will take longer to freeze and will provide additional protection against icing. Rock salt would likely bounce off the road and provide no benefit.

Motorists are being advised to keep a safe following distance from any trucks spraying the brine solution as they will be traveling at slower speeds.
