Some school systems in north Georgia were delaying the start of classes Friday morning amid fears of some ice on roads and highways from a winter storm that blasted other areas of the South.

Forecasters at the National Weather Service said black ice would be the main concern early Friday, particularly on bridges and overpasses.

The Georgia Department of Transportation said there had been limited reports of "isolated icing" on a few north Georgia roads as of 3 a.m. Friday.

School systems delaying the start of school by two hours included:
Catoosa
Dade
Dalton
Dawson
Fannin
Forsyth
Gilmer
Habersham
Lumpkin
Murray
Union
Walker
White
Whitfield

Administrators announced that Gordon County and Calhoun city schools would be closed Friday.

In Atlanta, city workers were told they could report to work at 9:30 a.m. Friday except those performing essential services.

Near the city, police shut down all of the southbound lanes of Interstate 85 after a wreck around 6 a.m. Friday, backing up traffic at the start of Friday's rush hour. The lanes had reopened by 6:30 a.m.
