I downstreamed the ATLANTA CH2 LIVE NEWS (ABC) on the internet way up into the night watching everything. At that time they had no idea how the fire got started but there was a hugh stocking of things under the freeway there awaiting for a new cable installation I think they said... Lots of PVC items and fiber optics cabling...
The last news I heard no one was hurt from the ordeal. They got real lucky... The scenes from the stranded cars and not moving traffic was one big parking lots as far as you could see in both directions. This happened during going home from work rush hour time... The NEWS said folks eventually just abandoned their cars and walked home...
What a mess it was...
