The Georgia Department of Transportation and the State Road and Tollway Authority are planning safety improvements on the Interstate 85 Express Lane in the coming weeks. The work includes widening the buffer and adding a 3-foot tall barrier between the lane and the remaining travel lanes from Ga. 316 to Old Norcross Road in Gwinnett County. Overnight lane closures in the Express Lane and the lane next to it will be required, with motorists unable to enter the southbound Express Lane at Old Peachtree Road and Ga. 316.
