RE: Bridge collapse
I haven't seen concrete bend like that since I left the turd world.
North America is a continent, South America is a continent.
Central America is incontinent.
It is common to use way too much water in the mix so that the concrete is easy to mix and to place.
After the concrete sets, the excess water eventually migrates out of the body of the concrete leaving it porous with greatly reduced compressive strength.
