The Marietta Street Island is a strip of greenspace that runs along, you guessed it, Marietta Street. It serves as a median between the two sides of the busy street. It’s a little bit surreal to stand in the middle of Atlanta traffic, in the middle of the road, no less. The Henry Grady statue, is near the intersection of Forsyth and Marietta and designates the junction “Henry Grady Square.” The statue, as stated by the plaque, has been there since late 1929.
