Decatur or some authority greatly shortened the light for East College traffic at the intersection of East College and South McDonough. In addition, someone painted a left turn only arrow on East College for left turns on to S Candler/Trinity. So, if you are traveling east on East College towards the intersection with South Candler, you cannot use the left lane to drive through the intersection even though the left lane continues on the other side of the intersection. This is senseless because, again, there are two eastbound lanes on East College both before and after the intersection at S Candler. Limiting cars going through this intersection to just one lane causes traffic to back up horribly on East College, even during the low volume times of day - and because this left only arrow is so senseless, it seems to be an error in how the street was painted when the new lights were turned on.
