Work to widen Interstate 985 to six lanes could start as early as 2022, according to the Georgia Department of Transportation. The project, estimated at $81 million, could run from Interstate 85 in Gwinnett County to Mundy Mill Road, or Exit 16, in Oakwood. “I think this widening is needed in light of our region’s projected population and employment growth,” said Sam Baker, transportation planning manager for the Gainesville-Hall Metropolitan Planning Organization, the Hall County area’s lead transportation planning agency.
