The fire broke out around 6 p.m. SKYFOX 5 was came across the scene near the MARTA train barn.
Atlanta fire officials said they have struck at least two alarms to try to fight the fire. They believe the fire was fueld by giant spools of plastic utility conduits which were being stored under the overpass.
Prior to the collapse, structural engineers told FOX 5 News that they are worried about the fire melting the metal under the bridge because of the intense heat.
A dark smoke plume could be seen for miles around the fire.
No firefighters were hurt in fighting the blaze.

A massive blaze underneath Interstate-85 in Atlanta, Georgia, has engulfed and destroyed a portion of the highway and left cars stuck both north and southbound.
I-85 northbound collapsed at Piedmont Road after less than an hour of the flames being reported.
After the collapse, around 7:30pm EST, Sgt. Cortez Stafford of the Atlanta Fire Department told Fox 5 Atlanta the fire was being "contained" and that no firefighters were injured.
Stafford did not confirm the source of the fire, but previously Fox 5 Atlanta had reported plastic conduit, which protects electrical wiring, was suspected to have fueled the inferno.
