Bingo!

See my post #25...

AH SO....it was SUPPOSE to be 2x thicker...

It’s encouraging to learn that my instincts are still relatively intact!

They got me home and they saw this screw up...

However — if they were suppose to be 2x thicker - then the prudent engineer would have added at least another 50% safety factor since this was a bridge in a FREEZING environment HIGH over WATER in a GROWING metropolitan area.....as part of the INTERSTATE HWY system.

Yeah, they should have been at least as thick as the steel in the U-Channel or I beams, which looks to be at least twice as thick as those thin plates. After all they are expected to carry some of the load from those beams.
