The new Wal-Mart Neighborhood Market, along with Taco Bell, on busy Ga. 60/Thompson Bridge Road in Gainesville will have something in common next year — a traffic light. As of now, it is set to be activated after the grand opening, said Amanda Henneberg, Wal-Mart spokeswoman. Wal-Mart, which is paying for the new signal, “usually installs signals close to opening,” said Teri Pope, district spokeswoman for the Georgia Department of Transportation.
