It turns out that Georgia Department of Transportation maintenance crews needed only a few days instead of two weeks to repair asphalt on an Interstate 85 stretch that reached Ga. 20/Buford Drive near the Mall of Georgia. Last week, the DOT was warning about traffic delays in overnight work on northbound lanes between Exit 99 at Ga. 140/Jimmy Carter Boulevard and Ga. 20, or Exit 115. “There is no good time to work on the interstate in Gwinnett County, but the best of the worst times is overnight weekdays, so that is our plan,” District Engineer Brent Cook said at the time.
