Part of Interstate 85 collapsed north of downtown Atlanta Thursday night after a massive fire broke out under the busy highway during afternoon rush hour traffic.
The fire broke out at around 6 p.m. Atlanta fire officials told Fox 5 the blaze caught giant spools of plastic utility conduits which were being stored under the overpass.
No injuries to motorists or firefighters were reported. Georgia State Patrol Capt. Mark Perry told the Atlanta Journal-Constitution that terrorism is not suspected.
Prior to the collapse, structural engineers told FOX 5 they were worried about fire melting the metal under the bridge. Witnesses say troopers told motorists to turn around on the bridge because they were concerned about its integrity.
The bridge collapsed at around 7 p.m. Foam trucks were eventually brought up from Atlanta's Hartsfield-Jackson International Airport to smother the remaining fire.

Here's what the fire looked like before it got WAY out of control.
This will have the effect of causing traffic patterns to change in and around the Atlanta area. I like Atlanta for their Waffle Houses.
High concentration of Waffle Houses in and around Atlanta. It truly is a sight to behold. You do not have Waffle Houses in New York City. But if there were, I would definitely go to Waffle House more often.
In the photo you posted it appears that the area beneath the bridge was being used to store some sort of flammable material. Looks like rolls of something - cable, pipe, hose, etc.
It is being reported as coils of industrial PVC conduit. There were also long lengths of industrial PVC pipe. All very flammable...
all over Tennessee also...
there are 2 in my town...
The phenomena is creep
The steel does’nt melt but deforms under load

Steel melts. It depends on the temperature. I’ve used straight oxygen to cut steel using the molten steel as a fuel.
Well, of course it melts...... but the temperature must be very hot to reach the steel melting temperature required for melting or cutting or welding
Waffle House would go broke quickly if they did that! We have six locations in our little area of GreenAcres just NW of the NW Atlanta suburbs.
WHY are they storing flammables under steel bridges?
I’ll be taking MARTA to work today. I’m a state employee—all state employees in the metro area start work at 10 am today.
It’s a convenient location. Google is doing a major fiber optics upgrade in Atlanta.
All over DFW too. Got one just 2 miles from the house over on I35.
At about 950Deg F, a steel beam will fail under it's own weight. A wood beam will hold until it burns through.
I am not an engineer, but I spent much of my life working with them. If I have questions about structural strength, I will ask one of them, Not some Hollywood b*^ch.
Steel, depending on the type, can melt at 2400 deg F. It becomes pretty soft around 1400F. It’s not beyond the realm of possibility that PVC, with the chimney effect, the get it that hot.
Google pulled out of that. It’s ATT doing the installation. Now whose flammable cables were under the highway I don’t know
