Granted it was a smaller project (tho’ still substantial), the collapsed main span of the Egner’s Ferry Bridge in KY was replaced in a few months...

The entire bridge was replaced in a bit over 4 years. There was not a big rush on the new bridge as the repaired bridge was deemed safe, but, IIRC the builders did cut the construction time of the new bridge by about a year.
Umm, you’re talking about Maryland, DEI central headquarters, Buttiboy and the Biden administration this time. Good luck with those incompetent hacks getting anything accomplished.
