I was speaking to someone yesterday and they said the 78, and the 22 and the 1&9, when referring to highways. I asked them is they were not from this area, and they were from California. Out there they say the 405, or the 101. We just say we are taking 22 or route 22. We never say the 22, it sounds bizzare if you do. We also do not normally use the term freeway here.
