I was down here today to re-clinch RI 138 and RI 138A. While the signage situation is as muddy as ever, I would recommend adjusting this as Duke87 suggested.
For RI 138, while the sign I pointed to (and another approaching the same junction) suggests a reroute, there is no further signage following that way or on any route it would likely be rerouted to, the existing route is well-signed, and there are orange signs for Newport, suggesting that this more likely either detour signage that never got removed, or simply in error with the arrows pointing the wrong way, rather than a planned reroute.
For RI 138A, the sign I pointed to is the only one suggesting that RI 138A exists north of the connector; nothing at the roundabout or the new roadway for RI 138 suggests this. That sign is likely just missing a TO banner. For the connector road, nothing on RI 138 NB that I was able to see (didn't actually go this way, but I was keeping my eyes peeled for anything that looked like route signage in the other direction, though it's possible I missed something). RI 138 WB says the connector road is "TO" RI 138A, while the EB guide sign suggests it is RI 138A itself.
An yes, RI 238 signage appears to be gone. When I clinched it in 2019, the only sign I recall seeing was
this one. That sign is now gone, probably removed when the intersection was reconfigured to favor RI 138A as the thru route.
