I sleuthed the location from this news image:
The underslung covering is for the paint work that led to the discovery of the damage. I think this is at Palmer Ave. & Crown Road under the approach on the PA side of the actual pan.
From other closeups it appears that there are two parted longitudinal roadbed supports. The truss shown in the posted FR article is just beneath the roadbed, and above the cross girders that provide the structural support.
So, sure it's bad, but the actual bridge structure itself is not compromised. A fatal failure from this damage would take the form of a collapse of a roaddbed slab, I think, and this is probably not imminent.

Well, I was "all wet" on this, not surprisingly, I guess.
The fracture is in an I-beam which IS part of the superstructure, along the top edge of the "box" which the girders form. There appear to be two fractures in some of the pictures, but these are fractures in the top and bottom flanges of the I in an I-beam which is "lying flat" along the top edge, as mentioned.
Just for the record ...
