As long-awaited work gets underway on the new bridge on Ga. 284/Clarks Bridge Road at Lake Lanier, the DOT last week released a fact sheet that features these work-hour restrictions: Lane closures are allowed weekdays 9 a.m. to 4 p.m. and overnights from 6 p.m. to 6 a.m. Lane closures are allowed weekends starting at 6 p.m. Fridays and lasting until 6 a.m. Mondays, unless a boating event is scheduled at the Lake Lanier Olympic Center. Work on the roadway and in the water will stop at least 12 hours before an event begins. The contractor, E.R. Snell of Snellville, must maintain two-way boat traffic on Lake Lanier through the project area at all times, and won’t block the boat ramp area parking or launch area except for the areas being changed or rebuilt.
