The Atlanta Medical Center is located at 303 Parkway Drive, which is about a 20 minute walk from the Civic Center station on the red/gold rail line (see walking/area map). It is a straight walk down Ivan Allen Jr./Ralph McGill Blvd. After exiting the station, head south on West Peachtree Street toward downtown and turn left on Ivan Allen Jr.
You can also choose between two bus routes:
Bus 99 from the Midtown, North Avenue (weekday non-rush hour only) or Georgia State station. The bus route travels down Boulevard with stops at the Medical Center.
Bus 16 departs from Five Points and travels along Ralph McGill with a stop at Parkway Drive and Boulevard.
Piedmont Hospital is located on Peachtree Street in between Midtown and Buckhead (see map). It is not in walking distance from a MARTA rail station, but you can take bus 110 from either the N7 Buckhead, NE7 Lenox or N5 Arts Center stations to get there.
The most direct route is to catch the northbound 110 bus at the Arts Center. The bus travels up and down Peachtree Street and has a stop at the hospital and the neighboring Shepherd Center.
If you get on bus 110 at the Buckhead station, make sure it is a southbound bus (take the first set of stairs out of the station to street level). Be advised that both the Arts Center and Buckhead stations have the 110 bus going both north and southbound. If you aren’t sure if you are on the right bus, just ask the driver.
