Designed by Sky Design, the signs have replaced previous interpretive signs installed by the Corporation of Olympic Development in Atlanta in 1995. Sign content was developed in partnership with project historian Dr. Karcheik Sims-Alvarado.
The mural enhancement features large scale images of historic buildings, landmarks, and cultural institutions which exist or previously existed along Auburn Avenue. The mural design team was led by husband and wife Ron Huffman (of Wood PLC) and Therese Huffman (of Signature Design). Project elements were fabricated and installed by DeNyse Companies, and the underpass lighting elements were installed by Brooks Berry Haynie & Associates.
