So, looking into this due to new GSV from Dec '24 in some of the area.
4C has been striped of it's exit number. But, there's president to keep the label as is (Exit 349 on I-95 in FL was previously signed, but lost in the C/D conversion in that area).
5C has had the same thing happen to it as 4C. I would keep this as-is, as it's still signed as part of the
Exit 5 split.
Exit 7 is still Exit 7 as of Dec '24, so, renumbering hasn't happened in this area yet.
