Why people hate government

Could there be any possible explanation for why road crews had to do landscape work this morning on the median strip of Santa Monica Boulevard - work that effectively shut down one westbound lane between Century City and the 405 and backed up traffic? Or why another lane was shut down near Overland because a new sign was being installed, also backing up traffic. Isn't this the sort of routine maintenance work that's supposed to handled during off hours, like weekends? Just wondering...
