    Just gonna fill in the underpass with foam expanded recycled glass.
    With extra loads of Do Not Cross tape being deployed, the surrounding neighborhoods are economically toast.
    I must have travelled that route a few times about 60 years ago.
    After the WTC collapses, how can anyone, especially engineers, be surprised that steel melts and burns?

    Those neighborhoods are suffering from detours already, getting this fixed rapidly will improve quality of life.

    Steel did not melt and burn.  Steel quickly loses all strength when it gets mildly hot - well below melting temperatures.

    Buildings encase steel in concrete.  Not for structural purposed,  To protect steel from heat - a fire.

    It's open again. I was surprised the aerial shots of the traffic I expected them to drop the speed limit down through the temporary fix, but all six lanes are zipping through there like it never happened.

    Atlanta – I-85 bridge collapsed in a fire – 43 days
    Oakland – collapsed ramps -26 days
    Washington I-5 bridge – 27 days
    Philly I-95 bridge collapse from fire – 12 days.

    I read by the time the permanent (ha, no such thing with infrastructure) fix is done, $30 million.
    Oh well, better to pay for the fix than be the guy that started the fire.

     Freedom is just another word for nothin' left to lose.
