Scanning Google Street View (March 2019 imagery), I found this set of state highway signage at the foot of the NB ramp from I-49 to LA 98/Gloria Switch Road (exit 2):
https://www.google.com/maps/@30.294672,-92.024198,3a,44.8y,18.3h,87.63t/data=!3m6!1e1!3m4!1sxC8vcYh99jY1lJbPZo9Q9g!2e0!7i16384!8i8192
What to make of this designation? Temporary project number? Contractor sign goof? Hidden frontage road designation? It is unlike any other number DOTD has assigned.
This appears to have been a fresh install as of the month the imagery was captured (note construction in vicinity).
All the other signage at the interchange appeared to be correct.
As far as I know this road is still LA 98. Later Street View from I-49 appears to show the signs corrected (to East and West LA 98).
My guess is that it's a contractor mix-up.

I don't know how contractors mess this stuff up. You can literally google it.
This is why, when making examples, you need to use obviously-fake placeholders, like "0000", "9999", or "XXXX".

I believe Louisiana's 4-digit routes can only begin with 1 or 3.

Apparently the dude running the sign machine didn't know that, though. "0000" would probably be more likely to make the guy go "Hey, boss..."
you build what the plan says even if you are almost certain it is wrong. generally the sign shop has no clue about any of it...just the drawings
