Dawson County motorists will see a big change in traffic flow at one of the area’s busiest intersections, starting Monday night. The Georgia Department of Transportation plans to convert Ga. 400 at Ga. 53 from a traditional signalized intersection to what will be Georgia’s first “continuous flow” intersection. The changeover is set for 10 p.m. Basically, drivers will be able to make left turns before the two roads cross, with separate lanes carrying them out of straight-through traffic.
