just a look at the early 70s car carcasses of New York. Must have been too difficult to get them to a junkyard?

The above isn't photo shopped. It's the West Side Elevated highway, that was designed so damn badly, that by the time they finished making it ( 22 year long project finished in 1951) it was already falling apart and unable to handle long truck and trailer combos due to narrow on-ramps and extremely tight turns. No doubt it was a windfall contract to reimburse unions for election results, and it then was an eyesore for another couple decades (shut off in 1973 not destroyed until 1987) until they figured out what to do to get rid of it and replace it with another highway.
