State transportation officials are planning new toll lanes on an interstate south of Atlanta, in Clayton and Henry counties.

Georgia Department of Transportation officials outlined the plans during a public meeting Tuesday in McDonough.

The project calls for barrier-separated, reversible lanes along a 12-mile stretch of Interstate 75. The tolls would cover a stretch of I-75 from State Route 138 in Stockbridge to State Route 155 in McDonough.

The lanes would run northbound during the morning rush hour and southbound in the evening.

It could cost motorists up to $6.50 each way to use the toll lanes, which will be optional.
