Signed over Selma Avenue in Wendell and over Nash Street in Middlesex (Nash County). Forms a "J" shape.

Although the original N.C. 23 was rather long (Whiteville to Louisburg at its maximum length), it had no 23x spur routes while it existed. 

231 was extended west to Wendell in 1948 or early 1949 over a previously unnumbered road. 

For 1933, all of 241 was also part of U.S. 311 (1933 official state map, right). The 241 designation was killed by 1934 as part of the first phase of the great renumbering. U.S. 311 was renumbered as part of U.S. 501 by 1935.

Runs over East Main Street and North Wall Street in the town of Benson. Goes through a lot of other small, forgettable towns too.

Around 1938, 242 was extended south from Roseboro to end at N.C. 53, very close to where 53 hit U.S. 701. In 1939, the modern 242 from Salemburg due north to 421 was opened as a new road, superseding the Odom Road alignment. 

By 1946, and perhaps earlier, 242 was extended further south. It was run through Elizabethtown along U.S. 701 and ended at Business N.C. 211 (which was mainline 211 back then) in Bladenboro. The 1946 General Drafting map shows this extension, but the '46 official state map doesn't. The highway was extended all the way to its current southern terminus, at least partly over perviously existing roads, by 1949. 

Around 1951, 242 was extended to the north. It was run partly over U.S. 421 to end at N.C. 50 just south of Benson. 242 was further extended through Benson to end at I-40 when the Interstate was opened in 1989.

Georgia 246 has several sharp curves as it descends, and as a result the road passes back into North Carolina at least twice over a 3/4-mile stretch. Some maps, including USGS topos (below) and the North Carolina-issued highway map of Macon County, imply that 246 changes back into N.C. 106 for the short stretches where the highway runs through North Carolina: the short stretches of road in N.C. are explicitly labeled 106. However, this is belied empirically by the fact that 246 seems to be entirely maintained by the state of Georgia: the pavement and all other characteristics of the road do not change, and there are no signs confirming any change of highway number. The only place the state-line crossing is posted in either direction is at the crossing farthest east, where 106 crosses into Georgia for the first time (or going the other way, where 246 enters N.C. for good). 
  

Lacking any signage, visible evidence suggests Georgia 246 partly runs through North Carolina without changing numbers. As far as this site is concerned, if N.C. wants this road, it's gonna have to put up signs.
