I noticed that too. I hope with you...sigh.
Earlier on I heard over the scanner they were closing down the interstate...I thought it had something to do with the congestion and mobility for emergency responders. Was surprised to learn a couple hours later it was still closed.
I believe they were worried about another explosion as there was still fire..and there are fumes that are dangerous, too..
The descriptions and pictures are frightening indeed.
The original fire crew that went to put out the fire has not been accounted for I just heard.
The scene itself is still too dangerous to investigate.
