An update of sorts on the resigning efforts . . . Passing through the Mercer County section of I-95/I-295: There are a few signs that have not been changed yet by NJDOT -- they are somewhat random. I-95 confirmations are still out there, though most have been removed. No new I-295 confirmations yet.
Delaware River Joint Toll Bridge Commission has started changing exit numbers and pull through signs, at least on the New Jersey side. Using greenout and overlays, since most signing will be removed because of the Scudder Falls Bridge construction. Exit 76 now exists. So does Exit 10, at least on one sign leaving New Jersey which is for the Taylorsville Road interchange upon entering Pennsylvania.
I went by that area yesterday, for a job visit at nearby TTN airport. Regarding that for-mentioned Exit 10B-A BGS; it appeared that there was the
OLD EXIT 31 sign (that should've been taken down years ago) was modified to read
OLD EXIT 51A-B.
It's worth noting that the stretch of I-95 (Future I-295) in PA still has most of its
OLD EXIT XX signs around. When PennDOT re-signs its stretch; one has to wonder whether they'll just place new numbers onto the old squares similar to what was done for the lone Exit 10B-A BGS or just replace the old panels with new ones.
Who knows, maybe PennDOT will stupidly place a new set of
OLD EXIT XX square next to its older counterparts. Either that or modify the originals to read
OLD-OLD EXIT XX.

Back to the NJ side of the river: for one supplemental Exit 1 (new Exit 76) sign for the State Police Museum had its
1 listing replaced with a larger
76 panel. Such is large enough that half of the new panel extends beyond the main panel. Personally, I would expect this sloppiness to come from PennDOT not NJDOT.
