Public Transportation Options Between Atlanta and Alpharetta

There is no MARTA rail station directly in Alpharetta, but you can use MARTA bus and park-and-ride options along GA-400.

MARTA Rail + Bus

   • North Springs Station
     7010 Peachtree Dunwoody Rd, Sandy Springs, GA 30328

2. From there, use:

   • MARTA bus routes that serve parts of North Fulton County (routes and coverage can change, so check the most current route map before you go).

it’s worth checking whether a commuter bus from a park-and-ride lot fits your schedule.
