Stop making highway signs that thank WDOT and the contractors that are doing the construction work. Their thanks are the paychecks they receive.
I can't tell you how many times I've seen state roads and intersections with multiple signs - all on their own post. Seems like some of these could be consolidated on one pole. Does the road crew going out to put up a new sign even LOOK at the other posts in the same area? Guess it's another example that since they get paid by the hour, they'd rather put up a new one and waste more of our money.
We all know that any added capacity will be clogged within a week (okay, a year or so). This is true always and everywhere. Save a few billion and keep it the way it is.
