Emergency Culvert Replacement Leads to Full Closure of SR 280/South Cobb Drive in Cobb County

Effective Tuesday, March 19, a full road closure will be implemented on State Route (SR) 280/South Cobb Drive from Fairground Street SE to US 41/SR 3/Cobb Parkway. The closure, set to commence at around 10 a.m. after morning rush hour, is essential for the emergency replacement of a culvert at this location.

Motorists are advised to adhere to posted detour route signage to circumvent SR 280/South Cobb Drive during this period. The primary detour route suggests using US 41/SR 3/Cobb Parkway SE, SR 120/South Marietta PKWY SE, and Fairground Street SE. Additionally, a secondary route via US 41/SR 3/Cobb Parkway SE, SR 120/South Marietta PKWY SE, and Atlanta Street SE has been identified for assistance in navigation.

Georgia DOT, in collaboration with city and county traffic operations teams, will monitor traffic flow along the detour route. Signal timing adjustments will be made as necessary to alleviate congestion during peak travel times.

The full closure of SR 280 is anticipated to last for approximately eight weeks, contingent upon weather conditions, with the project slated for completion in mid-May 2024. Real-time travel updates can be accessed through preferred wayfinding apps or by dialing 511GA.

The need for the emergency culvert replacement arose on Saturday, March 9, 2024, following a washout triggered by heavy rainfall from recent inclement weather. The culvert slated for replacement, dating back to the 1940s, has surpassed its expected lifespan.

Georgia DOT urges motorists to anticipate delays and assures close coordination with city and county officials, Dobbins Air Reserve Base, and Lockheed Martin to minimize travel disruptions. Real-time travel information on traffic conditions can be obtained by calling 511GA, visiting 511ga.org, cobbcommute.org, or downloading the 511 Georgia app.
