ATLANTA -- The Georgia Department of Transportation's new ramp meters will be turned on beginning Wednesday, October 10.

The meters were installed on Interstate 85 entrance ramps at State Road 20 in Buford (Exit 115) and on State Road 400 at McFarland Road (Exit 12).

According to Teri Pope of GDOT, the meters are turned on before rush hour, and will operate at various times of the day depending on traffic flow. When on, a green signal allows one car to pass through the ramp every 3 - 5 seconds and merge onto the freeway.

"We'll monitor these new ramp meters very carefully. If traffic starts to back up on the ramp, sensors will speed up the meters to allow more vehicles to move through. If our cameras show traffic spilling out onto the surface streets, we can turn them off completely," Georgia DOT Traffic Engineer Scott Zehngraff said.
