Edgewood Avenue has its origins with the Atlanta & Edgewood Street Railroad Company, originally authorized to run horsecars along Foster Street to what was then the separate village of Edgewood.
At the time, on the present route of Edgewood Avenue, there existed two streets: Line Street, which ran from Peachtree Street east to Pryor Street, and Foster Street, which ran east from Calhoun (now Piedmont Avenue) due east towards the town of Edgewood.
