Traffic both into and out of Cartersville on Ga. 20 is crawling at best this evening following at least one traffic accident. Motorists heading east toward Cartersville report long lines of traffic, mostly at a standstill. Apparently authorities are jockeying vehicles, letting one lane flow and then switching to the other lane. The Google map above shows areas of solid red where traffic is stopped in both directions as well as breaks inbetween. We’ll have a photo soon.
