Also in Asheville on I-240 WB and US 19/23/74A where they split for I-240 to head south at Patton Ave, the US 74 A shield is not present along with US 19 & 23 for Patton Avenue. Wondering if US 74A is on its way out as it’s redundant to have it follow closely its parent Route while concurrent with two other mainline US designations.

It seems that US 74A is sporadically signed west of I-240 Exit 5B (where US 74A and US 70 join I-240 WB). Using Google Maps, I did see one EAST US 74A sign east of the Haywood/Patton intersection, however, I did not see one just north of I-40 Exit 44 (only has a NORTH US 19/23 sign) nor did I see a US 74A sign with US 19/23 on Patton west of the I-240 split. Maybe US 74A should be truncated at the US 70/Tunnel Road intersection or at the I-40/240 interchange.
I do not see NC changing US 74A back to US 74. US 74A is sort of the scenic or leisurely route between Asheville and Forest City. US 74 has been designed as the quicker routing between Asheville and Charlotte as well as between Charlotte to Wilmington.
US 74A was US 74 until the 1994 reroute of US 74 along the completed freeway from Forest City to I-26 and along I-26 to Exit 44 on I-40 (with the later 1998 reroute of US 74 along its current route along I-40 and the Exit 27 connector). It would not be financially feasible to change the US 74A routing back to US 74—just leave the routings as they currently are. US 74 in NC has become one of the more important highways in the state. It is no longer the single state US highway it once was.
As an aside, and not dealing with NC, with the 1987 extension of US 74 to Chattanooga, TN, TN should sign US 74 prominently from the NC/TN line to I-75 Exit 20, utilizing the US 64 Bypass around Cleveland, TN. That is where US 74 should have its national western terminus–not at the I-75/I-24 interchange. That is very pointless to have an unsigned concurrency for 18 miles, much less hardly sign US 74 in TN. If the Chattanooga-Asheville corridor wants to be promoted, have improved signage of US 74 in TN. If the extension was approved, show it.
