GDOT crews are working to clear the roads in North Georgia as ice has caused trees to fall across the region. Many incidents are causing power outages, and teams are preparing for an overnight refreeze. ATLANTA – As road crews transition from brining operations to actively clearing roadways of fallen trees and debris, the Georgia Department of Transportation is warning motorists to avoid driving as an overnight refreeze is expected Sunday. Teams have been working nonstop the past few days to keep roadways passable as a winter storm moves through North Georgia, Nathan Johnston, communications officer for GDOT District 1, said. District 1 is home to some of the hardest-hit areas, with places like White County reporting that 70% of customers are without power. Crews are dealing with issues in areas like White, Habersham, and Union, while also prioritizing critical infrastructure, including I-85, I-985, and SR 400, as overnight refreeze is expected. “Temperatures are beginning to drop, and we want to emphasize the importance and danger of black ice on the roadways, especially at night,” Johnston said.
