Now that I think about it... The CO22 signage is particularly old since it hasn't been on Sable Boulevard for a long time. The CO44 signage is "more recently old", but I think the fact that the sign off of US85 has been changed to "Old CO 2", they're kind of announcing its removal. The weird/dumb thing is that the road that goes by the arsenal is literally called "Highway 2" as opposed to any other street name, even though it's no longer CO Highway 2.
I also forgot to mention in our message that the exit from I-76 to Sable Boulevard doesn't have any reference to CO2, which it would have been not too long ago at least southbound.
This is one of the few times I think I'm in favor of removal.
