Are the businesses along the portion of Atlanta Highway that flooded in May open? All businesses along that stretch are open, but those in the Wayne Center had to relocate. Storms on May 19 dumped some 7« inches of rain on Flowery Branch in six hours, which overwhelmed area culverts.At one point during the disaster, a wide stretch of Ga. 13/Atlanta Highway between Wayne Drive and Moonie’s Texas Barbecue was about 6 feet underwater.
