Instantaneously the Fulton "authorities" caused mile long backups into Cobb county. When the Cobb residents scomplained, they got the usual government arrogant BS about it being set correctly, but that Fulton would "study the problem" and might or might not change the setting.
Then one night someone put several rifle rounds through the timing mechanism, and all of a sudden Fulton decided that it was in their best interests to fix the light the way it was before they screwed with it. Just say'n.
Was that Johnson Ferry Road? Crosses over the Chattahoochee River? If so, I grew up close to there.
