Overnight Closures on I-16 at SR 307/Dean Forest Road

Lane closures will allow crews to pour bridge decks for the new Diverging Diamond Interchange configuration

The Georgia Department of Transportation (Georgia DOT) has announced a set of Interstate 16 lane closures at State Route 307 (Dean Forest Road) this week allowing contractors to pour bridge decks advancing the Diverging Diamond Interchange (DDI) project.

The closure impacts are scheduled to begin Thursday, Sept. 28, at 7 p.m. and end Friday, Sept. 29, at 6 a.m., for I-16 westbound. The backup date for any postponement is Monday, Oct. 2, if needed. A second closure is scheduled to begin on Thursday, Oct. 5, at 7 p.m. and end on Friday, Oct. 6, at 6 a.m., for I-16 eastbound. A backup date is scheduled for Monday, Oct. 9, if needed.

During this closure of I-16, motorists will use Exit 160, Dean Forest Road to cross over and return to I-16. Law enforcement officers will be on site to control traffic, in lieu of traffic signals. This method of closure reduces impacts and potential congestion caused by a single lane closure and traffic pacing by allowing continuous flow.
“This demolition signals the home stretch in construction for this major improvement in Chatham County,” said Trevor Brown, Georgia DOT Design-Build project manager. “Once this project is completed, motorists will see significant improvements to congestion and safety at this interchange. Stay tuned for updates about how you’ll use the new interchange coming up in early 2024.”
