Mainly for Oscar, but there’s technically precedent. I managed to sneak MS 67, AL 152, and AL 158 into usansf despite their overall lack of controlled access. Either Tim didn’t notice or he didn’t care…this being back in the CHM days.
In fairness, though, some of that might have also been “fudging the definitions” to get at least SOMETHING at the state level into the books. Both states have a considerable lack of state route freeways…
