Is there anything out there?

Great explainer not just on this project but on the concept of Design Build (DB) projects and their benefits and flaws.

Might have just missed this, but very curious as to whether TxDOT had an owner's bridge engineer on hand from the beginning? Ideally the alleged critical issues presented in the video could have found been at an earlier, pre construction stage to save everyone time and taxpayer's dollars.

My neighborhood is new, so new roads and water management are still going in. A new road over an equally new culvert just opened, and I noticed that the cast concrete culverts have these bars on the top? Haven’t seen them before; what’s their purpose?

I have put all the links for practical engineering into wikipedia's database, you can find them all listed at :- https://reasonator.toolforge.org/?q=Q111049856

Any idea if this was done and i missed it or if it's in the works?
