NC 206 #1: An original state route that ran from NC 20 (now US 74 Bus) Shelby northeast through Cherryville to end at NC 16 (now just Aspen St (Lincolnton).
About 1928, NC 206 east may have been truncated to west of Lincolnton as NC 27 was routed through using some of NC 206.
In 1931, NC 206 was renumbered as part of NC 150.
In Lincoln County NC 206 used Old NC 150/Crouse School Rd and SR 1407 from Roseland to NC 27.
