Despite being considered a subway, only the Red and Gold Lines are underground and use a tunnel under Broad Street between Garnett and Peachtree Center.

The Blue and Green Lines, on the second level, are located at-grade below the intersecting elevated street viaducts in Downtown Atlanta.

Outside the paid area are the MARTA Ride Store, Reduced Fare Office, and Lost and Found, and a Zip car address.

This is the busiest station in the MARTA system, handling an average of 57,000 people per business day, and over 27,000 on weekends.

[citation needed] The initial opening of the station was almost delayed because of construction on the lower level.

[citation needed] Major renovations to both the east and west street-level plazas of the station began in April 2006.
