U.S. Route 421 (US 421) traverses approximately 328 miles (528 km) across North Carolina; from Fort Fisher, on Pleasure Island between the Atlantic Ocean and Cape Fear River, to the Tennessee state line near the community of Zionville. The highway is nominally labeled "north" and "south" throughout North Carolina, though it really follows a general northwest-southeast path. The segments from Buies Creek to Sanford and from Greensboro to Boone are almost due east-west, with compass west corresponding to the signed north direction.
A majority of the highway is part of the North Carolina Strategic Highway Corridors system. Because of this designation, the state has made numerous changes converting a rural two-lane highway into a major freeway/expressway with 4 or more lanes. Numerous former segments of the highway named "Old U.S. Route 421" are found along the entire route.
US 421 starts at a parking/dock area on the Cape Fear side of Pleasure Island. Within one-quarter mile (0.40 km), US 421 passes through its unsigned junction with NC 211 and the approach to the Fort Fisher Ferry Terminal, where travelers can board to cross the Cape Fear River toward Southport. Immediately after the ferry terminal is the Fort Fisher State Recreation Area, where the first and second battles of Fort Fisher took place.
The highway continues north, going through popular tourist destinations in New Hanover county: Kure Beach, and Carolina Beach. US 421 eventually enters Wilmington along the river side of the city. At Wooster Street, it goes west, overlapping with several other highways and funnels through Brunswick County before returning in northwestern New Hanover County; there it links with Interstate 140 (I-140) before continuing north towards Clinton.
From about three miles (4.8 km) north of the I-140 interchange, the road remains a four-lane divided highway for another ten miles (16 km). After its intersection with NC 210, it becomes a rural two-lane highway for much of its remainder until Dunn. The exception is in Clinton, where it follows Faircloth Freeway to bypass the city, running concurrent to US 701 for about four miles (6.4 km). There is one rest area located just north of Delway. US 421 meets I-95 in Dunn. From Wilmington to Dunn, the route parallels I-40 approximately ten miles (16 km) to US 421's east.
After crossing downtown Dunn and Erwin immediately to the east, US 421 becomes a four-lane divided highway again until reaching Lillington, with a short segment in Buies Creek containing a center lane and reduced speed limit as it crosses Campbell University. Upon reaching the junction with US 401, NC 27, and NC 210, all four routes collect onto a thoroughfare heading south over the Cape Fear River into downtown Lillington. US 421 then splits off to the west, becoming a two-lane expressway until Sanford (though speed limit never actually increases).
Upon reaching Sanford, US 421 formerly followed Horner Boulevard with NC 87 to cross downtown, but it is now rerouted onto the recently completed Sanford Bypass, the entirety of which is freeway. It runs concurrent with NC 87 Bypass until the US 1/US 15/US 501/NC 87 interchange, from which it continues until the end of the bypass near Cumnock.
For the rest of its route until Greensboro, US 421 remains almost entirely free-flowing. It is an expressway from Sanford to just south of Siler City, bypassing Goldston, Bear Creek, and Siler City. From here to the Greensboro Urban Loop, US 421 becomes a freeway, bypassing Staley, Liberty, and Julian. All of these cities/places were connected by US 421's old alignment, now called some variant of Old US 421 for the majority of its route.
Near Pleasant Garden, US 421 joins I-85 on the Greensboro Urban Loop, staying with the loop as I-85 leaves and I-73 joins it. Another six miles (9.7 km) later, US 421 leaves the Greensboro Urban Loop to join I-40 and continue westward towards Winston-Salem. Near Kernersville, US 421 remains with I-40 Business, a former alignment of I-40, going through downtown Winston-Salem.
West of Winston-Salem, I-40 Business ends at an interchange with mainline I-40 and US 421 continues as a freeway towards Yadkinville and Wilkesboro. When the highway nears North Wilkesboro, the highway passes North Wilkesboro Speedway (access via exit 282); there is also a visitor center built in 2009 as the state's first environmentally friendly rest area, located at mile marker 283. As US 421 enters Wilkesboro city limits, it downgrades to an expressway with various stores and restaurants along it.
As it leaves Wilkesboro, US 421 begins a gradual climb in elevation, until approximately five miles (8.0 km) from Deep Gap, where it climbs up the steep escarpment along the eastern edge of the Blue Ridge Mountains. Access to the Blue Ridge Parkway is located at Deep Gap, as US 421 continues on towards Boone.
As US 421 approaches Boone, the expressway comes to an end just before an intersection with Old US 421. The road continues into Boone as four lane boulevard, becoming two lanes at the intersection with US 321. US 321 north, US 421 north, and NC 194 south all run concurrent through the downtown area via King Street. After leaving Boone, US 421 continues on as a two-lane road to the Tennessee state line, heading on to Mountain City.
US 421 overlaps with two state scenic byways: the Cape Fear Historic Byway, in downtown Wilmington, and the U.S. 421 Scenic Byway, between Deep Gap and Boone. Two of North Carolina's Bicycle Routes run concurrent for portions of US 421. North Carolina Bicycle Route 5 is concurrent from US 421's southern terminus at Fort Fisher to north of Snows Cut, through downtown Wilmington to Blueberry Road near Montague, North Carolina, and a short portion near Coats. A small part of North Carolina Bicycle Route 3 is concurrent with US 421 in downtown Wilmington.
This article is in a list format that may be better presented using prose. (June 2016)
- 1931 - US 421 officially appears on highway maps starting from Winston-Salem (junction with US 70/170) to Boone at King/Hardin Street intersection (junction with US 221/321). It was solely within the state of North Carolina and was completely overlapped with NC 60.
- 1932 - US 421 was extended both north and south. North from Boone, it extended to Sugar Grove where it then replaced US 321 heading towards Mountain City, Tennessee; US 321 redirects towards Elizabethton, Tennessee. From Winston-Salem, the highway is routed to Wilmington following NC 60.
- 1933 - Highway was realigned around Boone (using a straighter alignment) and in Greensboro (Market Street).
- 1934 - NC 60 is completely removed from its original route, leaving US 421. NC 60 gets renumbered on a short highway in Cherokee County, where it continues to this day.
- 1936 - US 421 is extended south from Wilmington to Carolina Beach, Kure Beach, and Fort Fisher, replacing NC 40.
- 1951-1952 - US 421 bypasses Clinton (on what would be today's Faircloth Freeway). The Wilkesboro area is realigned through town to North Wilkesboro.
- 1954-1955 - US 421 is rerouted going west out of Wilmington via US 17/74/76, then north following NC 133.
- 1957-1958 - US 421 is realigned onto a straighter routing between Deep Gap and Wilkesboro. US 421 is redirected out of North Wilkesboro, old routing is renumbered as US 421-A (Now US 421 Business). US 421 is placed onto one-way streets within Winston-Salem (using 4th and 5th streets), it is also rerouted in Greensboro going from Market Street to the freeway O. Henry Blvd. Between Erwin and Dunn, US 421 is realigned onto a new four-lane expressway.
- 1962-1963 - US 421 is realigned onto a new road near Sugar Grove and Zionville, leaving the communities of Amantha and Mabel. Between Yadkinville and Winston-Salem, US 421 is given its current alignment, expanding to a freeway after the Yadkin River to I-40; it then overlaps with I-40 (later called Business 40) through downtown Winston-Salem. In Harnett County, US 421 is moved north, avoiding the community of Mamers, and enters Lillington via Front Street. US 421 is straighten out through Harrells.
- 1964-1968 - US 421 becomes one-way streets through downtown Greensboro (Market Street and Madison/Gaston Avenues). US 421 is rerouted onto the new Faircloth Freeway in Clinton.
- 1969-1970 - US 421 is rerouted onto the new Cape Fear Bridge in Wilmington. US 421 is realigned around Bonlee and Bear Creek.
- 1971-1984 - US 421 completes its bypass around Wilkesboro. Between Greensboro and Staley is upgraded to expressway standards (Joseph M. Hunt Jr Expressway) and bypasses the communities of Pleasant Garden, Climax, Julian, and Liberty. US 421 is rerouted in Sanford, avoiding the community of Broadway.
- 1987-1990 - The Siler City bypass is completed. US 421 is rerouted going north around Greensboro then going south on Henry Boulevard (US 29).
- 1994-1999 - US 421 is removed from all surface roads from Kernersville to Greensboro, follows I-40 to Joseph M. Hunt Jr Expressway.
- 2000-2003 - US 421 is realigned and widen to 4-lane freeway between Yadkinville to Wilkesboro and a 4-lane expressway between Wilkesboro to Boone (though some parts already pre-existed for before 2000). This completes US 421 as a 4-lane (or more) highway from Sanford to Boone.
- 2008 - US 421 is realigned in Greensboro to follow the new southern loop, overlapping with I-73 and I-85 to Joseph M. Hunt Jr Expressway. This was done to give drivers a route direction to Winston-Salem after I-40 returned to its original routing after one year on the southern loop.
- 2012 - In Boone, a 1.1-mile (1.8 km) section, known as King Street, was widened to four to six lanes with a raised concrete median from US 321 (Hardin Street) to east of NC 194 (Jefferson Road). The project cost $16.2 million.
In Kernersville, the roadway improvements and extension of Macy Grove Road will include the construction of a new interchange with I-40 Business/US 421. Property acquisition is to begin in 2012.
In Winston-Salem, shared with I-40 Business, a 1-mile (1.6 km) section from west of Fourth Street to east of Church Street has begun project development studies to completely upgrade and streamline. The project includes removing the existing pavement and replacing it with new concrete pavement, upgrade and modernize entrance and exit ramps, and replace most of the bridges on and over the freeway. Work began on this rehab in 2018, and is expected to be complete by January, 2020, with the closure of several miles of U.S. 421. Concurrent with the rehabilitation of the route, the Interstate 40 Business designation will be dropped from the entire route, and the route will remain U.S. 421 and take on the new name Salem Parkway.
In New Hanover and Brunswick counties, the Cape Fear Skyway has begun its project development studies (since 2007) to build a toll road and bridge that will bypass Wilmington. Early estimates range from $950 million to $1.1 billion. The environmental impact study is expected to be completed in 2014, a record of decision and a complete financial feasibility will be done in 2015.[needs update]

Note – Exit numbers west of Winston-Salem are aligned when US 421 went north around Greensboro in late-1980s/early-1990s. As a result, from realignments in Greensboro, the actual mileage vs. exit number mileage is off by an average of 3.5 miles (5.6 km).
