State transportation officials announced last month that the speed limit on a stretch of Ga. 400 in Dawson County will be lowered to 55 mph.
Dawson County Commission Chairman Mike Berg said he received notification of the upcoming change early last week.
"We've requested this for years," he said. "There have been several fatal wrecks along the stretch, so we've wanted this to happen for a long time."
Now posted at 65 mph, the stretch of highway starting at the Forsyth County line to about 1,015 feet north of Harmony Church Road will be lowered to 55 mph as of Feb. 16.
Berg said the lower speed limit is a permanent change.
The lower speed limit on Ga. 400 comes as transportation crews make strides in the construction of the new continuous flow intersection going in at Hwy. 53.
Similar in principle to diverging diamond interchanges like those now in place at some busy Interstate 85 and 285 interchanges, the continuous flow intersection is designed to move left-turning vehicles out of traffic's main flow by using a series of access roads and longer left-turn lanes.
The $14 million construction project would be the state's first continuous flow intersection.
According to information released in a Georgia Department of Transportation video, motorists traveling on Ga. 400 would follow traffic signaling devices directing them to drive across the oncoming lanes into new lanes on the far left side of the road.
Construction is expected to take 18 months to complete and would be staged so as not to disrupt traffic.
Once complete, DOT predicts traffic congestion will be reduced by 85 percent.
The project completion date is set for April 30, 2017.
