U.S. 421-A  none remaining
History: Since there are no active US 421-A routes, the previous 421-A's will be presented in the order of their creation 

The first US 421-A shows up on Esso map insets of Greensboro from 1933-36, shown as running along Walker St, which had been US 421's original routing inot Greensboro. 1934-35 Gousha Maps do not show this as a primary route, and I have no other sources to consult. At any rate, US 421-A didn't last long, I don't think, and has been unnumbered since then. Check out the 1936 Esso scan below...
1936 Gen Drafting

The second US 421-A appeared in 1951 or 1952, when US 421 was rebuilt on a new alignment in western Clinton. 421-A used Lisbon and McKay Sts through Clinton, a partial multiplex with US 701-A. In 1960, US 421-A was renumbered to US 421 Business. Today the route carries no primary number..  
1952 Shell

The 3rd US 421-A appeared between 1957 and 1958 as a US 421 bypass of Wilkesboro was built to the south. This US 421-A ran along E St. and C St. in North Wilkesboro before exiting via NC 115. This routing became US 421 Business in 1960, as it remains today.
