FLOWERY BRANCH — Design work should begin next month on the Northeast Georgia Health System’s new South Hall hospital. “Master planning is where we are right now,” said Anthony Williamson, health system vice president at a meeting Tuesday morning of the Greater Hall Chamber of Commerce’s South Hall Business Coalition. “We’re looking at where on the site the hospital is going to go, whether it’s going to be tall or short and how it’s going to lay out,” he said, speaking at the Hall County Library System’s Spout Springs branch.
