Why do people in Los Angeles usually refer to their numbered highways with "the" (for example, US 101 is "the one-oh-one")?
Perhaps this is done in other regions as well, but as far as I know it seems to be specific to Los Angeles. According to Wikipedia
, US 101 is just called "one-oh-one" in Northern California and Oregon. Another article
also notes a linguistic divide between Northern and Southern California in this regard.
In my hometown of Richmond, VA, when we colloquially refer to our major interstates and arterial highways (I-95, I-64, I-295, US 1, US 301, US 360, etc.) we do so without using "the" (so just "Ninety-five" or "Eye-ninety-five"). We also have named highways that also have numbers, like Chippenham Parkway (Rt. 150). (Interestingly we don't refer to it with "the".) (I'm aware that in many places, especially in LA, they use the names of highways more often. E.g. "The Santa Monica Freeway" is used in conversation, not just in official documents.)
Is this specific just to LA? Is it done in other regions? How do you refer to numbered (or named and numbered) highways where you live?
