It is the ramp meter traffic light. The red light is out, and on the sign that tells cars that the ramp meter is on, the bottom flashing yellow light is out.

Thank you for reporting this. The Georgia Department of Transportation (GDOT) maintains ramp meter signals. In collaboration with GDOT, we'll repair the light. If you have any questions, please contact us at 678-297-6260.
