Someone did finally call to answer the question, thank you. The message simply said that a left-turn arrow is in the approval process with GDOT. That would solve part of it.

The other part is having lane markers so that people stay in their lanes. People turning right (North) onto Roswell Road from Pitts and people turning left (North) onto Roswell from Ison could do that at the same time if drivers just maintained lanes instead of swinging out wide. That simple thing alone would *significantly* speed that intersection up - especially at that hour. Is there anything that can be done to make that happen? Lane markers?
