Well, the third image certainly looks like a reconstruction using the recovered parts. The first image is looking northeast from the east side of the bridge at the south end, and the second picture is looking northwest from the west side, directly across from the first location.
The reconstruction looks like it could include the visible members of the second picture, where I think I can see the patchy paint from the foreground of the reconstruction. It looks like that paint was applied over the “wiring” of the sensors, or whatever. I surmise that the light patch in the foreground of the reconstruction is where that “loop” was attached, and ripped off.
Compare the foreground box beam in the third image above, to the beam at Arrow 2 in image six of my post 45 of this thread, shape only.
If it was black before the collapse, and black while still in the water right after the collapse, why is it green, and a sloppy job of green to boot, now?
