Interstate 73/74

I take it North Carolina doesn't do "Old Exit Numbers" when they renumber an exit. That sign should say Exit 29, Old Exit 129 as a way to avoid confusion by the new exit number.

No, they tend to put out press releases with the new numbers and hope local media picks up the story. This is of little help though to out-of-state travelers with out of date maps or GIS apps.

Drove down Future-74 from Fancy Gap today. Confirmed that there have been no mile marker changes on I-77 and that every exit except for US-52 South have been updated. Again, it almost seems intentional since the overhead for Westinghouse was updated to Exit 39 while Exit 119 on the same structure hasn't been updated (29:47 in the video). In adding the timestamps in the description, I also discovered that US-52 North near Mt. Airy was also renumbered from Exit 17 to 18 (maybe to align with the renumbering of the same exit northbound from 140 to 18?).

EDIT
Here are a few higher quality/drier images...

An example of the new "Future I-74 Corridor" signs:


The aforementioned overhead sign using both 74 and 52 exit numbers:

Here's also a view of the interchange coming from Winston:

They did with I-26 20+ years ago, and I believe someone gave another example recently when this same question came up. NCDOT has cited high costs for aluminum delaying new license plates and other signing projects, plus the major budget crunch from Helene, so it's not surprising that they're not making temporary signs.

Here's a view through the interchange construction projects on the southern end of the project where I-74 will meet I-40 and NC-192:
