Piedmont Hospital is at 1968 Peachtree Road, closest to the Arts Center MARTA station on the red and gold rail line. It is not in walking distance from a MARTA rail station, but you can take bus 110 from three rail stations to reach the hospital.
The most direct route is to catch the northbound 110 bus at the Arts Center station. The ride is about 10 minutes. Exit the bus around the stoplight at Collier Road.
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 — Peachtree Road). 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.
