I visited the overpass yesterday. At first it appeared that that 1971 rehabilitation had involved replacing the steel stringers with concrete, but the concrete sheathing is damaged in places, showing the steel beams. There's a fair amount of old spalling on columns and beams, especially the older ones, but none appears substantial enough to cause concern.
There'd been a small brush fire down the tracks from the overpass and, at first, I associated that with the blackening of the beams and deck, but it is probably just a few decades of diesel smoke.
