Ga. 400 commuters in Forsyth County will get some relief starting today. The Georgia Department of Transportation had expected to wrap up weekend work, including widening and extension of the entrance ramp from Abernathy Road to Ga. 400 north and an additional lane on Ga. 400 north from the McGinnis Ferry Road overpass to the Big Creek Greenway Bridge. “These projects will improve the overall operation of Ga. 400 north by enhancing efficiency and increasing capacity,” DOT Commissioner Keith Golden said.
