 Signage plans for the Macy Grove Road Improvements project indicate that NC 150 will be rerouted around Kernersville, continuing on US 421 (Salem Parkway) to the Macy Grove Road interchange (exit 221) and then following the under-construction northern extension of Macy Grove Road around the east side of Kernersville to rejoin the existing NC 150 alignment just north of Smith Edwards Road.The interchange between US 421 and Macy Grove Road began construction in June 2013 and opened in November 2015, and construction began on the extension of Macy Grove Road in June 2018.North Carolina Highway 150A (NC 150A) was established in 1956 when NC 150 was rerouted onto new primary routing bypassing southeast of downtown Lincolnton; the old alignment became NC 150A.
