NC 284: An original state highway, running from VA 10 (current US 23 Bus) Waynesville east along today's US 276 (with a few old loops) east to about NC 215, then it used SR 1924 and 1876 through Woodrow, then SR 1105 which loops over US 276 a few times. A brief run with present US 276, then SR 1885 Old Michael Rd. NC 284 then used US 276 south (except probably used Campers Ln in Cruso) over the mountain and past Looking Glass Falls to US 64/US 276/NC 280 jct. NC 284 then jogged southeast on Ecusta Rd to end at NC 28 (now Everett Rd) Pisgah Forest. The 1921 Official Map shows NC 284 ending here. In 1922, NC 284 was extended west with NC 28 to Brevard, then south as new primary routing along today's US 276 to South Carolina.

NC 284 original route

In 1930, NC 284 was extended as new primary routing northwest from Waynesville along today's US 276 to Dellwood, then north along 276 to Cove Creek, then northwest along "Old NC 284" through what is now Great Smoky Mountain Nat'l Park to end at the Tennessee State Line above Mt. Sterling (official maps imply 284 ended at Mt Sterling but 1930 and 1936 Haywood County maps show it running to state line).
In 1932, US 276 was assigned to NC 284 from Brevard to the SOuth Carolina line.
In late 1934, NC 284 was dropped from US 276, truncating NC 284 to US 64 Pisgah Forest.

NC 284 extended to S.C.

US 276 replaces NC 284

Around 1940, US 276 was extended to Waynesville, killing more of NC 284. Ecusta Rd has been secondary ever since.
In 1959 or 1960, NC 284 was replaced by more US 276 from Waynesville to US 19.

NC 284 extended to Tenn.

US 276 replaces NC 284 Waynesville to Brevard

NC 284 truncated to US 19

Both the 1968 Official and the 1968 Haywood County Maps show NC 284, but the 1969 Official shows US 276 replacing NC 284 from Dellwood to Cove Creek and the rest downgraded to secondary status.

NC 284 gone forever

Today, most of the old NC 284 northwest of Cove Creek is still unpaved. It is an interesting drive that shows what NC Routes were like decades ago. I can't speak to the scenery as my drive of most of this was in the middle of the night.
The Tennessee side of Old NC 284 is paved TN 32, which I drove from US 321 in the late 1980s. TN 32 is perhaps the twistiest road in the south but is not very well known like US 129. When I made this drive, after crossing into NC, there was still a NPS sign at the 4-way junction in Mt Sterling that still marked the continuing road ahead as NC 284. This sign is no longer there however.
