Using the Marta bus service bound for the Lindbergh Center Station in Uptown, it puts you less than a 3-minute walk from the Atrium.

After arriving at the Lindbergh Center Station, follow Main Street toward Tongue & Groove (T&G) (Google Maps)

straight across the street from there is the Atrium main entrance placed between two tall office towers.
