MARTA trains and buses do not travel to Marietta. However, there are several options for commuting there on transit via CobbLinc and car services. See below to explore options.
MARTA + Uber/Lyft
The fastest option is to combine a MARTA rail trip with a Lyft or Uber ride. If you are trying to get to downtown Marietta, take a red line or gold line train to the Arts Center MARTA station and connect with Uber or Lyft there.
For travel to the Cumberland Mall/Cobb Galleria/SunTrust Park area, you can request a car at the Dunwoody, Medical Center, Lindbergh Center or Arts Center MARTA stations for a 15-minute car trip (without traffic). From the airport, take any northbound train to the Arts Center MARTA station for the fastest commute.
CobbLinc buses also connect with several MARTA stations on a limited schedule (primarily weekdays) and travel to Marietta. It is free to transfer from MARTA to a CobbLinc, but if you are starting your trip in Cobb County, you’ll need to have cash value or a CobbLinc pass on your Breeze Card, available at all Breeze Card vending machines and online.
