Gee bobrk don't you folks call it "The 680" and "The Montague"?
I'm from the bay area... the freeways there are not prefixed by "the" and generally the number is more than the name. at least that's how it was when I left 13 years ago. -- flickr gallery | photo blog (rarely updated) | play mafia!
You are correct. The only freeways ever referred to by name are "The Bayshore" and "The Nimitz." Everything else is numbers. The other freeways have names, but they are memorial in nature and not directional like the LA ones are.
