The Bleckley Plaza Plan was a proposed engineering project in Atlanta, Georgia, United States. Proposed by architect Haralson Bleckley in the early 1900s, the project would have seen numerous railroads in downtown Atlanta covered by a large public plaza that would have run from the Georgia State Capitol to Terminal Station, covering much of The Gulch. The project, while considered at numerous points in the early 1900s, never came to fruition.
