U.S. Route 70 in North Carolina

U.S. Route 70 (US 70) is a part of the United States Numbered Highway System that runs from Globe, Arizona, to the Crystal Coast of the US state of North Carolina. In North Carolina, it is a major east–west highway that runs from the Tennessee border to the Atlantic Ocean. From the Tennessee state line near Paint Rock to Asheville it follows the historic Dixie Highway, running concurrently with US 25. The highway connects several major cities including Asheville, High Point, Greensboro, Durham, Raleigh, Goldsboro, and New Bern. From Beaufort on east, US 70 shares part of the Outer Banks Scenic Byway, a National Scenic Byway, before ending in the community of Atlantic, located along Core Sound.

US 70 is an original US Highway, signed on November 11, 1926, when the US Highway System was approved. Since then, the highway has been realigned in places. One of the larger extensions of US 70 came in 1931 when the highway was extended concurrently along North Carolina Highway 101 (NC 101) from Beaufort to Atlantic. While sections of US 70 have been converted to freeway standards, along most of the routing it is a four-lane highway. Several new projects beginning in the 2000s have placed US 70 on interstate grade freeways, such as the Clayton and Goldsboro bypasses. On May 24, 2016, AASHTO assigned the Future I-42 designation to the majority of US 70's routing east of Garner. Additionally, a short freeway segment in east Durham was officially designated as I-885 on June 30, 2022, a route that connects I-40 to I-85 through the Research Triangle Park and east Durham.

Route description

US 70 travels through several diverse regions in North Carolina, including the Bald and Black Mountains of Western North Carolina, the rural Foothills, the urban Piedmont, the farmlands of the Inner Banks, and the coastal communities of the Crystal Coast. All of US 70 east of Durham, and smaller segments including Statesville to Salisbury and Lexington to Greensboro, are listed in the National Highway System, a network of roads important to the country's economy, defense, and mobility. US 70 also overlaps two state scenic byways: the Appalachian Medley, from Hot Springs to Walnut, and the Clayton Bypass Scenic Byway, from I-40 to US 70 Bus.

Western Mountains and Foothills

US 70, in concurrency with US 25, enters from Tennessee as a two-lane mountain highway meandering through the Bald Mountains. In Hot Springs it crosses the French Broad River and the Appalachian Trail, then goes northeasterly through Tanyard Gap to Hurricane. Proceeding south, it goes through the Walnut Mountains and then joins NC 213 near Walnut. Continuing on a more southeasterly routing, it becomes the US 25 Bus./ US 70 Bus. split-off towards downtown Marshall at Mashburn Gap. At the Hayes Run Road interchange, NC 213 splits and continues towards Mars Hill. Before US 25 Bus./US 70 Bus. rejoins at Ivy River Road, the highway widens to four lanes; afterwards, it follows along Ivy Creek before crossing the Madison/ Buncombe county line.

In Weaverville, US 25/US 70 joins Future I-26/ US 19/ US 23 (exit 19), then continues south on the Morris L. McGough Freeway to Asheville. US 25 separates at Merrimon Avenue (exit 23), continuing solo into downtown Asheville. At the Patton Avenue interchange, US 70 switches to an I-240/ US 74A concurrency as it goes east along the Billy Graham Freeway. At Charlotte Avenue (exit 5B), US 70/US 74A splits from I-240 before it goes through the Beaucatcher Cut. At College Street, which changes into Tunnel Road, US 70/US 74A passes through Beaucatcher Tunnel (built in 1927). On the eastern side of Beaucatcher Mountain, US 70/US ;74A goes through a commercial corridor that leads to Asheville Mall, where US 74A splits and continues along South Tunnel Road and connects with I-240 at a unique three-level diamond interchange. In the East Asheville area is the historic Oteen Veterans Administration Hospital Historic District as well as the Blue Ridge Parkway. At Jones Mountain, US 70 leaves the Asheville city limits and begins its parallel north of I-40, as it goes through Swannanoa and Black Mountain. At Ridgecrest, US 70 merges with I-40 (exit 65). At Swannanoa Gap it crosses the Eastern Continental Divide (elevation ) and enters McDowell County.

At the top of the gap, in addition to a reduced speed limit there is a truck information station that requires all trucks to go through before continuing. The following descent is a 6% grade along Youngs Ridge to Old Fort, along which are several reduce-speed warning lights and three runaway truck ramps. It is likely that, on both on the ascent and the descent, most trucks and some cars will be going slower than posted speed limits, and that, despite the fact that this section is six lanes wide, slower vehicles may be traveling in the passing lanes. At Old Fort, US 70 splits from I-40 (at exit 72) and travels through the downtown area and by the Mountain Gateway Museum and Heritage Center. East of Old Fort, US 70 travels northeasterly towards Marion and forms the southern boundary of the Pisgah National Forest. At Pleasant Gardens, it connects with NC 80, which travelers can follow towards Mount Mitchell, the highest peak east of the Mississippi River. Crossing the Catawba River and entering Marion, US 70 connects with US 221/ NC 226 and then forms a short concurrency with US 221 Bus. along Main Street. East of Marion, US 70 connects with NC 126 in Nebo, where travelers can visit Lake James State Park.

Entering Burke County near Bridgewater, US 70 passes through Glen Alpine and then enters Morganton, where it forms a brief concurrency with US 64 as it proceeds along Fleming Drive, while US 70 Bus. passes through the downtown area. Continuing east, it goes through the towns of Drexel, Valdese, Rutherford College, Connelly Springs and Hildebran before crossing into Catawba County at Long View. In Hickory, US 70 serves as the town's commercial corridor as US 321 Bus. begins its concurrency at the US 321 interchange. In Conover, US 321 Bus. turns at Northwest Boulevard towards Newton and then crosses NC 16. Continuing east through Claremont and Catawba, US 70 crosses the Catawba River for the second time and enters Iredell County.

Piedmont Triad and the Triangle

After passing through Celeste Hinkle and by the Statesville Regional Airport, US 70 enters the city limits of Statesville and connects with US 64/ NC 90 at the intersection of Newton Drive and Garner Bagnal Boulevard. Passing south of the downtown area, it begins to parallel the Norfolk Southern Railway south to Salisbury. Crossing US 21 at Shelton Avenue and I-77 (exit 49A), it leaves Statesville and proceeds southeasterly along Statesville Boulevard, also known as the Jim Graham Highway, through an area of farmland and factories that are wedged between the four-lane highway and the railway. After crossing into Rowan County, US 70 goes through Cleveland and shares a short concurrency with NC 801 near Barber before entering Salisbury. On Jake Alexander Boulevard, US 70 shares a concurrency with US 601 until the Rowan Mills area, where it switches onto Main Street with US 29 and later NC 150. Traveling northeasterly through downtown Salisbury, it then goes by the North Carolina Transportation Museum before passing through Spencer. At the Yadkin River, the four-lane highway reduces to two-lanes as it crosses over into Davidson County. Adjacent to the bridge over which US 29/US 70/NC 150 travels are the Wil-Cox Bridge, a concrete arch pedestrian bridge, and two North Carolina Railroad (NCRR) Warren truss bridges.

At from the Yadkin River, NC 150 splits towards Churchland while US 29/US 70 merges with I-85/ US 52 (at exit 84). After a concurrency, I-85 splits off and continues towards Greensboro, and I-285 begins (at exit 87). Entering the Lexington city limits, additional route changes occur; I-285/US 52 departs (at exit 87) towards Winston-Salem, and US 64 merges from Mocksville. After skirting north of downtown Lexington, US 64 departs again towards Asheboro, and the highway continues northeasterly as a four-lane expressway. After passing through Thomasville, it then proceeds briefly through Randolph County and then into High Point and Guilford County. Staying south of the downtown area, it connects with I-74 with its second three-level diamond interchange. Near Groometown, the highway merges with I-85 for a brief concurrency (between exits 118 and 120A). To connect with I-73/ US 421 (Greensboro Urban Loop), travelers must continue on I-85 or stay in the left travel lanes; this stretch of freeway features numerous sign gantries and surface markings to guide travelers. Continuing northeasterly along Preddy Boulevard into Greensboro, it connects with South US 220 (at exit 35), where travelers can connect to Interstate 85, or go northbound to reach I-40 west or the Greensboro Coliseum. Merging onto I-40/US 220/US 29 (at exit 219), the following stretch of freeway is known locally as "Death Valley", a nickname given because of the high number of deaths due to car crashes in this area, owed to having five routes attached to it. Separating from I-40/I-85 Bus. at the O'Henry Boulevard interchange (at exit 223), US 29/US 70/US 220 continue north, passing by the North Carolina A&T campus to the Wendover Avenue interchange, where the 3 routes break up. With US 29 continuing north along the expressway towards Reidsville and Danville, Virginia, and US 220 North going west on Wendover Avenue to follow Battleground Road to Summerfield, US 70 again proceeds solo, east on Wendover Ave towards Burlington. At the eastern edge of Greensboro's city limit, US 70 connects with I-785/ I-840 (Greensboro Urban Loop). Leaving Greensboro and entering McLeansville, US 70 takes on the name "Burlington Road" as well as the Charlotte Hawkins Brown Memorial Highway. Here it is a two lane road, and is also an important route that connects McLeansville with other small towns such as Sedalia and Gibsonville, as well as the Rock Creek and Stoney Creek centers in Whitsett; east of Whitsett, it enters Alamance County.

Passing south of Elon, US 70 runs on Church St, a four lane retail corridor, as it enters Burlington's city limits. It connects with NC 87 and NC 100 as well as NC 62 as it enters downtown Burlington. Sharing a brief concurrency with NC 62 through the downtown area, it then proceeds southeasterly to Haw River. As it nears the town of Haw River, it then goes northeasterly again to bypass the town and crosses over the Haw River via Three Governors Bridge; heading easterly again, the highway drops back to two lanes after connecting with NC 49. At Mebane, US 70 crosses into Orange County. Passing through the communities of Miles and Efland, and parallels the NCRR railroad just to the north, US 70 makes a unique median divide in Duke Forest to merge with the I-85 Connector (SR 1239); constructed in the mid-1950s when US 70 was rerouted here onto what is now I-40/I-85. Crossing the Eno River, US 70 passes along the northern edge of Hillsborough, while US 70 Bus. goes through its downtown area. Crossing the Eno River again, it borders along the Eno River State Park, while traveling through another area of the Duke Forest. At Eno, US 70 merges onto I-85 (exit 170), while US 70 Bus. continues along its former alignment to Bennett Place.

Entering both Durham and Durham County, I-85/US 70 maintains an east–west routing north of the downtown area, along a stretch of highway dedicated to Dr. John H. Franklin. At exit 174A US 15/ US 501 join the freeway; at exit 176B US 501 departs and continues north along Duke Street. US 70 leaves I-85/US 15 at exit 178, and forms a concurrency with I-885, which begins at the interchange. I-85 and US 15 continue north toward Oxford and Petersburg. Traveling on a southeasterly direction along four-lane freeway in East Durham, it has interchanges with US 70 Bus./ NC 98 and Carr Drive. Soon after I-885 departs from the route to head toward I-40, US 70 downgrades to an expressway. At Bethesda, Miami Boulevard (SR 1959) continues south into the Research Triangle Park, while US 70 enters Wake County along New Raleigh Highway.

After crossing Raleigh city limits, US 70, here called Glenwood Avenue, makes a connection with I-540 (exit 292), which goes to the front entrance of RDU Airport; the following Lumley Road/Westgate Road interchange (at exit 293) goes to the North Cargo and General Aviation area of RDU Airport. Adjacent to the airport is William B. Umstead State Park. With NC 50 joining US 70 at Creedmoor Road, US 70 crosses under I-440/ US 1 after passing by Crabtree Valley Mall. Inside the Raleigh Beltline, US 70/NC 50 travel through a residential area until Wade Avenue, where they join US 401 along Capital Boulevard. In the downtown area, Capital Boulevard splits into Dawson and McDowell Streets; various sites are adjacent or nearby, including the North Carolina Museum of Natural Sciences and North Carolina Museum of History (via Jones Street), the North Carolina State Capitol (via Morgan Street), the Raleigh Convention Center, the Red Hat Amphitheater, and the Duke Energy Center for the Performing Arts (via South Street). Leaving the downtown area after the Martin Luther King Jr. Boulevard/Western Boulevard interchange, Dawson–McDowell Streets merge and become Saunders Street, which promptly exits the Raleigh Beltline crossing under I-40/US 64. In Garner, US 401 departs along Fayetteville Street towards Fuquay-Varina, followed by NC 50 along Benson Road towards Benson. East of Garner, US 70 merges with I-40 (exit 306A), while US 70 Bus. head towards Clayton. At the Wake/ Johnston county line, US 70 splits from I-40 for the last time (at exit 309) and onto the Clayton Bypass.

Coastal Plain and Down East

After along the Clayton Bypass, US 70 crosses US 70 Bus., from Clayton to Smithfiled, and changes from freeway to expressway. Continuing through Wilson's Mills and crossing the Neuse River, it enters Selma, where travelers have the choice to stay on mainline US 70, connecting with US 301/ NC 39/ NC 96, I-95, and US 70A, or take US 70 Bypass to avoid all that. Southeast of Selma, US 70 Bus. rejoins from Smithfield and near Princeton, US 70A rejoins from Pine Level. East of Princeton, it enters Wayne County. Northwest of Goldsboro, the US 70 Bypass spurs northeast towards I-795, while US 70 goes into Goldsboro. In Goldsboro, it also connects with I-795 and then joins a concurrency with US 13/ US 117, passing north of the downtown area while US 70 Bus. goes through it via Grantham Street. After , US 117 separates and continues north; at Berkeley Boulevard, US 13 separates towards Snow Hill and also connects to Seymour Johnson Air Force Base. East of Goldsboro, US 70 Bus. reunites along Ash Street. Entering Lenoir County, near LaGrange, US 70 Bypass reconnects with US 70, where the highway continues east. US 70 connects with NC 148 at Falling Creek, which goes to the North Carolina Global TransPark. As it enters Kinston, it is joined by US 258, from Snow Hill, as they both bypass south of the downtown area, while US 70 Bus./ US 258 Bus. go through the downtown area. Near Dupreeville, US 70 Bus./US 258 Bus. rejoin; they then separate, with US 258 continuing south to Richlands, while NC 58 shares a short concurrency before continuing towards Trenton.

Bypassing south of Dover, in Jones County, US 70 travels through the Great Dover Swamp, most of which has been drained and converted to farmland. After it enters Craven County, south of Cove City. At Clarks Road (exit 409) is the Craven County Rest Area. At exit 410A US 17 joins in concurrency as the freeway enters New Bern. The freeway, designated the Richard Spaight Memorial Highway, passes southeast of the downtown area and enters James City after crossing the Trent River via the Freedom Memorial Bridges. Traveling southeast along the U.S. Marine Corp Highway, US 70 passes by the Coastal Carolina Regional Airport, and then enters the Croatan National Forest
