Between 1963-67, US 52 Bus was placed on one-way splits in central Mt. Airy. SB used the original two-way route on Main St and NB was put on Cherry St to Renfro St.
Between 1969-72, US 52 Business was removed from Main St (now SRs 1668 and 2111) in central Mt. Airy and placed on two-way traffic on an extended Renfro St. The short Cherry St piece became US 601 NB and NC 89 EB.

US 52 Business #3: Born in the mid 1990s? The route does not appear in any way on official maps through 2009 and it also does not appear in the NC Route change list that goes back to 1997. This had been secondary ever since mainline US 52 was removed from 1st St Albemarle in the late 1980s. In Oct 2010 (NCDOT), US 52 Business was extended from its south endpoint west with NC 24-27-73 to meet the new US 52 alignment (old NC 138).
