Watch for Black Ice

When wet roads freeze, the threat of black ice is possible.  Black ice is a thin, often invisible sheet of ice that forms on the roadway, especially on bridges and overpasses and low lying areas. It can form at any time when temperatures drop below freezing and there is any form of moisture, from sprinklers, run-off or precipitation on the roadway. The Georgia Department of Transportation (GDOT) will use the Roadway Weather Information System to help identify potential timeframes for black ice to enhance monitoring of these roadways.  They will monitor black ice areas that were problematic during prior winter weather events and address it as soon as it occurs. GDOT does not clear local roads or roadways leading into subdivisions.
