The Georgia Department of Transportation will close South Cobb Drive near Dobbins Air Reserve Base Tuesday at 10 a.m. to replace a large drainage pipe that failed earlier this month.

The nearly 3-mile stretch of State Route 280, or South Cobb Drive, will be closed for about two months while the drain is replaced. The road closure begins at Fairground Street and ends at U.S. Route 41, or Cobb Parkway. Officials recommend motorists follow detour signs to South Marietta Parkway to avoid the road closure, according to the news release.

The culvert failed earlier this month after heavy rainfall caused a washout, Georgia DOT officials said in the release. The drainage pipe dates back to the 1940s and has “outlived its life expectancy.”

DOT officials aim to have the road reopened by mid-May, weather permitting. The state department “coordinates closely with city and county officials, Dobbins Air Reserve Base officials, and Lockheed Martin to ensure minimal travel disruption.” Motorists can also find real-time updates on road closures in several GPS navigation apps.
