I was hoping that aside from the concrete river block, that TransEd largely left American Bridge to do their thing entirely on the tawatina bridge.i did note that they might not be shareable/accessible. they were photos of some of the tawatina bridge piers with similar drilling and injection sites as those shown in transed's video. as the construction of the bridge above is actually quite different than the elevated roadway sections on the piers elsewhere, i was hopeful that we wouldn't see the same issues on the bridge piers. given however that we are seeing the same things, it seems like pier design or pier construction or material rather than poorly handled transmitted stresses are likely causative but that's still pure guesswork on my part.
I would bet money that it's again not a design issue but more construction/material issues as we've seen repeatedly. The fact it's a continual project wide fault from guideways to piers to sidewalks to bridges (Whitemud and tawatina) makes one think it's some sort of incredible failure by whoever was spearheading concrete engineering.
