The way RIDOT has been signing the old exit tabs has been questionable in workmanship and consistency.

1. No standard on the Dimensions (some are more square, other's tend to be longer)
2. No standard on the naming convention (I've seen old exit 27 labelled as "Old 27")
3. No standard placement (I.e. some signage is on the gore point exit sign, while other aren't)

This is almost as bad as a couple years back when a contractor was overzealous with putting in the Curvature warning signs for the offramps. Oddly enough it was also old exit 12 they messed up on. The contractor ended up mounting the 270 turn sign wrong. I think only after contacting the DOT was it corrected

If there is a silver lining, I'm thinking the lower number old exit tabs are being reused from I-295; at least they were consistent
