New Roadway Signage

Answer me this........Did the old road signs stop working? You know, the signs that say "CONSTRUCTION AHEAD".......Did someone find something wrong in the way they were worded?? Did they, Our Government, have to spend more $$$ in "Designing" these new HUGE signs? I mean...what the heck...we got the loans I guess, we might as well spend it. Is the mentality here? It surely couldn't be for the glorification of our government could it? I think the only thing they missed was that in all their design work, aren't they gonna need these signs to be in a language EVERYONE can read? I mean to be politically correct and all....just wondering...
