I remember the days when African Americans pretty much did all the concrete work in this country.
They've been pushed out by mexicans.

And yet they still vote 90% Democrat. They don't win awards for brains.

Supposedly the engineers were doing a stress test on the bridge when it collapsed
The bridge was just was movd into place last Saturday and was not yet open to the public.

Then cars shouldn't have been driving under it.
