Keeping the intersection of Sardis and Ledan roads open during the day is going to cost Hall County an extra $50,000 and extend construction by 20 days. A roundabout is in the works at the northwest Hall intersection, now a four-way stop that has been slowing school traffic and frustrating the community during peak hours. Hall County revealed last week that the builder, E.R. Snell Contractor, was going to close the road to traffic from July 31 to mid-September or maybe even October. But after the news broke, prompting public outrage that the intersection was going to close through the first month or more of school, the Hall County Board of Commissioners worked to change plans for the roadway . With the longer work period, the project will finish in early October at the earliest.
