Well, if the US ones are different, the Interstate ones are different
for the same reason based on what i've seen in Northern California on
I-5, US-199 and US-101:  California's egotistical enough to put it's
name on all route markers regardless of size.  "Interstate California 5,
US California 199", etc.
