A study of traffic in the Martin Road area of South Hall — near where a much-opposed interchange is being built — will be folded into a countywide freight study. “That way, we don’t have to seek additional or a new source of funding,” said Sam Baker, transportation planning manager for the Gainesville-Hall Metropolitan Planning Organization, Hall County’s lead transportation planning agency. And there would be likely freight movement at the planned Exit 14 interchange off Interstate 985 — a Georgia Department of Transportation project that could start as early as this fall — as the western side of the interchange is a growing industrial area.
