Hall County officials recently changed the speed limit on the road leading to the new Don Carter State Park off Lake Lanier, but nearby North Hall resident Terry Roberts is still concerned about drivers hotfooting through the area. Roberts, who has complained to the Hall County Sheriff’s Office about the problem, said speeders are common along Ga. 284/Clarks Bridge Road in both directions to North Browning Bridge Road, which leads to the park. Motorists are prone to tailgate and pass motorists abiding by the 55 mph speed limit.
