"We've seen a lot of motorists that need to make that left turn onto Overton Road," Brian Davis with ALDOT said.
"We've gone back and looked at the gaps there and seen that we have an opportunity to add a section to the signal head to allow that move to not only be made in a protected fashion, but at a permissive fashion."
The new, fourth signal head will be a flashing yellow turn signal which will allow drivers to turn onto Overton Road as long as there is no oncoming traffic on 280 westbound.
"We're trying to make progression along 280, so we felt like this is the best move.
People are accustomed to making that left permissively, anyway," Davis
said, referring to the traffic signal at the intersection before Highway 280 was modified.
