The U.S. Army Corps of Engineers has postponed the closing of Buford Dam Road for repairs to Monday.
Work on the 2-mile section that straddles Lake Lanier was supposed to start this week.
The road will reopen possibly before the Nov. 5 scheduled completion, said Chris Lovelady, the corps' assistant operations project manager at Lake Lanier.
During the closure, east-west travelers crossing the lake can take Ga. 369 to the north or Ga. 20 to the south.
Corps officials have estimated the closure could add about 15 to 30 minutes to commute times.
