Didn’t this happen in Philadelphia some years ago on I-95? A bunch of tires in a junkyard under 95 caught fire and the interstate collapsed?
Don't know, but this sort of thing happened recently in Oakland California, on the eastern side of the San Francisco/Oakland Bay Bridge linking I-80 exchange with several other interstate highways. Big tanker burned under multilevel overpasses and collapsed them. California CalTrans thought it would take half a year to fix it, governor hired a private contractor who said he could rebuild it in one month, and he did so, getting traffic moving within a month. It was an amazing feat out here.
