Multiple agencies responded to the call at around 7:45 a.m.
The cause of death was unconfirmed as of Wednesday night, but the man was hit by at least one car.
Authorities did not find an abandoned car in the area.
Bartow County Coroner Joel Guyton said there was a wallet with identification found on the man, but the body was so traumatized after being struck that his identity cannot be totally confirmed.
The identification found on the body was of a white man who was born in 1989.
The Georgia Bureau of Investigation said a positive I.D. will be made after an autopsy today.
The GBI is asking anyone with information concerning the investigation to contact the Emerson Police Department at 770-386-6696 or the GBI Office in Calhoun at 706-624-1424.
