The Metropolitan Atlanta Rapid Transit Authority will hold a public meeting about the concept on Sept. 26 at Alpharetta City Hall.
The Atlanta Journal-Constitution reports that several ideas are being explored, including adding buses, light rail or heavy rail along a 12-mile stretch of Georgia 400 from Dunwoody to Alpharetta.
Details about the cost and potential ridership of the proposed expansion were not available Thursday. However, officials said those figures would be presented at the public hearing.
