I-85 enters Cleveland County, North Carolina from Cherokee County, South Carolina near the small town of Grover. Most of the Interstate for its first few miles is generally rural in nature and remains four lanes. It has its first interchange with NC 216, which provides access to Kings Mountain National Military Park, with a welcome center shortly after. Later, the southbound lanes have an exit for US 29, which quietly merges onto I-85 and begins a concurrency. At milemarker 10, the Interstate meets US 74 at a unique weave interchange and US 29 splits off from I-85 for US 74 east. Both routes also enter Kings Mountain.
At this point, I-85 crosses into Gaston County and expands to six lanes from four. It enters suburban areas and traffic begins increasing from here. The Interstate then reaches Gastonia and has an exit for NC 274 (Bessemer City Road). Then it has its first major interchange with US 321, signed north for Lincolnton and south for the city's main business district. Traffic from US 321 south prior to 2017 was often congested due to I-85, and a new interchange was developed to help relieve it.[3] Past it, I-85 turns southeast, then east as it goes through more suburban areas, with restaurants, businesses, churches, and car dealerships that line the road. Along here, it intersects more state highways serving as Gastonia's main thoroughfares, including NC 7 (Ozark Avenue), NC 279 (New Hope Road), and NC 7 (McAdenville Road/Main Street) again; NC 7 provides access to the town of McAdenville. Here, many major retail stores and supermarkets are seen along I-85 as it continues on its eastward track to Belmont and expands even more to eight lanes. It reaches the main exit for Belmont at NC 273 near milemarker 27, then crosses the Catawba River, entering Mecklenburg County.
Charlotte to Greensboro
Right after entering Mecklenburg County, I-85 reaches a weigh station occasionally serving trucks on both lanes. Access to the U.S. National Whitewater Center can be done from Sam Wilson Road, its first interchange in the county. After that, I-85 meets I-485 at a stack interchange. This portion of I-85 is often congested due to the lanes merging into one.[4] As of 2024, from the US 321 interchange to I-485, the lanes are being widened to accommodate larger amounts of traffic.[5] Drivers wanting to access I-77 can get off at the interchange, or simply keep driving on I-85 to reach the Charlotte Douglas International Airport. A couple miles later, I-85 has an exit for the airport via Little Rock Road at a single-point urban interchange and enters the city of Charlotte. It has interchanges with Billy Graham Parkway, as well as two more single-point urban interchanges with NC 27 (Freedom Drive) and NC 16 (Brookshire Boulevard).
I-85 then has an interchange with I-77 and US 21 at milemarker 38 with a hybrid interchange and then traverses the northern portion of Charlotte. The routing through this portion is generally more suburban than urban in nature, with light industries such as truck terminals, warehouses, small manufacturing facilities, and small office parks lining the highway. More interchanges with minor but significant thoroughfares through the city such as Graham Street, Sugar Creek Road, and North Tryon Street appear. Here, I-85 turns more northward and enters the University City area. it meets NC 24 (Harris Boulevard) in this stretch and has an interchange with I-485 again, this time at a turbine interchange.[6]
I-85 southbound in Concord near the I-485 interchange
I-85 then crosses into Cabarrus County, immediately entering the city of Concord and dense commercial development. It passes exit 49 (Bruton Smith Boulevard/Concord Mills Boulevard), which is signed for several major attractions such as the Concord Mills mall and Charlotte Motor Speedway. Several miles later, it has a diverging diamond interchange with NC 73 and then crosses Coddle Creek. It meets US 29 a second time as well as US 601 nearing Kannapolis, the exit of which provides access to the North Carolina Research Campus. US 601 merges onto I-85, forming another concurrency as the two routes continue northward and meet a rest area. They do not enter Kannapolis, but have several exits signed for it. They cross the Cold Water Creek, which parallels them, before entering Rowan County and mostly rural areas. North of China Grove, the highway passes exit 74 (Julian Road) for an outlet containing several stores. Just before Salisbury, US 601 splits from I-85 at exit 75 for Jake Alexander Boulevard, and I-85 enters Salisbury where it meets US 52 at exit 76 with a single-point urban interchange. US 52 merges onto I-85 and the highway exits Salisbury. At Spencer, I-85/US 52 enters Davidson County and crosses the Yadkin River on the Yadkin River Veterans Memorial Bridge.[7] The route then meets with US 29, US 70, and NC 150 near the unincorporated community of Linwood at an unusual interchange. The interchange allows for direct access to NC 150 northbound and US 29/US 70 southbound. US 29 and US 70 converge with I-85/US 52 for a very brief distance, about two miles (3.2 km), before I-85 reaches an interchange that is accessible northbound only: I-285. At this point, all three U.S. Highways that overlapped I-85 leave the Interstate, and I-85 narrows back down to six lanes.[8]
The landscape becomes more rural as I-85 reaches just outside of Lexington and intersects NC 47 (Hargrave Road). Because the previous exit is a northbound-only exit, drivers going southbound must use NC 47 to access I-285. After its interchange with NC 8 (Cotton Grove Road), which is the main exit for Lexington, I-85 enters a large forest with tree-lined medians and crosses Abbotts Creek, then has an interchange with US 64. Past Holly Grove Road on milemarker 96, the northbound lanes cut under the southbound lanes and cross Hamby Creek. The reversed lanes of I-85 then pass over Squire Bowers Road and reach a rest area, as well as access to the North Carolina Vietnam Veterans Memorial Park. Once the lanes pass under Johnsontown Road around milemarker 102, the northbound lanes cross above the southbound lanes and return to normal direction.[9][10]
I-85 southbound at exit 113 for I-74 and NC 62
The tree-lined median then gives way to the city of Thomasville, where I-85 meets NC 109. It crosses into Randolph County as it enters the city of Archdale and intersects NC 62. I-85 enters High Point and has a parclo interchange with I-74 and the former routing of US 311. The exits are signed east for Asheboro and west for Winston-Salem. I-85 then passes through another forest with more trees lining the median and crosses the Randolph and Guilford branches of the Richland Creek as it enters Guilford County. Just outside Greensboro, it has a southbound interchange with US 29 and US 70 again. US 29 and US 70 form a brief concurrency with I-85 before the route enters suburban areas once more and reaches a very large and complex interchange with Groometown Road, Grandover Parkway, I-73, US 220, and US 421. US 29 and US 70 split off through the interchange, while US 421 joins I-85 from I-73 in a wrong-way concurrency. Because I-85 was rerouted around Greensboro after February 2004, it now follows the southern half of the Greensboro Urban Loop.[11][12]
Greensboro to Durham
Leaving the massive interchange, I-85/US 421 expands to eight lanes again and stays connected for just 4 miles (6.4 km) before US 421 departs the concurrency at exit 126 to head southeast for Sanford. Prior to the Greensboro Urban Loop, US 421 used to run along exit 126B, which is now signed for just Greensboro itself. Meanwhile, I-85 maintains its northeastward track and passes by a couple more exits before reaching its third auxiliary route, I-785, I-40, and I-840, the former and latter of which have their southern and eastern terminus at I-85 respectively. I-40 merges onto I-85 and the two routes share a rather long concurrency which travels entirely east–west for 31 miles (50 km). The concurrency here uses I-85's mileage instead of I-40's. I-40/I-85 enters more industrial areas and meets NC 61 before entering Alamance County. It travels right through the heart of Burlington upon mile marker 141, intersecting several of the city's main state highways, including NC 62 again, NC 49, NC 87, and NC 54. Businesses, restaurants, parks, and buildings can be seen lining the sides of the highway. Past a diverging diamond interchange with NC 119 (Mebane-Oaks Road), the highway enters Orange County and reaches another truck weigh station. I-40 then splits off southeast from I-85 to serve the southern portion of Durham and downtown Raleigh while I-85 continues eastward and narrows back down to four lanes.[13]
The following interchanges of I-85 before Durham County are rather substandard in quality due to the interstate retaining its original design. It meets NC 86 and later US 70, which forms another concurrency once again before entering Durham County. At milemarker 172, it meets the northern terminus of NC 147 (Durham Freeway), which connects to downtown Durham. I-85/US 70 then widens to six lanes again and then ten as it reaches the main city center and becomes urban in nature. It then has an interchange with US 15 and US 501, which both also join the concurrency. The highway passes NC 157 (Guess Road), and then US 501 splits off at Duke Street to head north. The other three highways continue on their way before meeting the western terminus of NC 55 (Avondale Drive). Just before exiting Durham, US 70 also departs the concurrency to head east alongside I-85's fourth and final auxiliary route, I-885, for the Raleigh–Durham International Airport and Raleigh itself while I-85 and US 15 remain joined.[14]
Durham to Virginia
North of Durham, I-85/US 15 narrows down to four lanes and passes several more minor interchanges before entering Granville County and suburban areas. The landscape gives way to rural areas and another forest, this time without trees lining the median as the highway crosses Falls Lake. US 15 departs I-85 at exit 186 to serve the town and city of Butner and Creedmoor respectively, whereas I-85 bypasses these areas. From here to Oxford, US 15 parallels I-85. The Interstate then intersects NC 56 outside of Butner and continues to make its way through the forest for about 10 miles (16 km) without any other interchanges. I-85 then crosses the Tar River and comes to another rest area. It meets US 15 at another interchange just near milemarker 202 nearing Oxford. Interchanges with NC 96 and US 158 immediately follow, then I-85 cuts into Vance County.
It immediately reaches the city limits of Henderson before meeting up with US 158 (Dabney Drive), and US 158 merges on I-85 to follow a short concurrency with it. The highway intersects NC 39, the main exit for Henderson, then US 158 splits off from the concurrency shortly after. At milemarker 218, I-85 has a southbound exit for US 1, which begins paralleling it for the rest of the Interstate's length. I-85 passes just west of Middleburg and has a parclo interchange with US 1/US 158 (Flemingtown Road) for the town of Norlina. I-85 then enters its final county in the state, Warren County. Before long, it bypasses Manson and continues to go through wooded forest with no development along the road. Just before exiting the state, I-85 has its final interchange in the state with US 1 and the northern terminus of US 401 near the unincorporated community of Wise. After that, it exits North Carolina and crosses the state line into Mecklenburg County, Virginia.
I-85 in North Carolina features a few dedicated or memorialized stretches of freeway.
Blue Star Memorial Highway: The official North Carolina honorary name of I-85 throughout the state that was approved on May 5, 1967.[15][16]

Dr. John H. Franklin Highway: The official North Carolina name of I-85/US 70, between Cole Mill Road (exit 173) and US 70 (exit 178), in Durham. It is named in honor of John Hope Franklin, an American historian and recipient of the Presidential Medal of Freedom.[27]
Parts of I-85 were already constructed before federal aid was available in the 1950s, as the state had been constructing sections of the Interstate Highway System since 1949. The Lexington Bypass north of Lexington—which at the time was signed US 29 and US 70—is now a part of I-85 Bus.[28] This was part of an 80-mile (130 km) expressway completed in 1955 between Lexington and Hillsborough.[29]
One planned road was the Salisbury bypass, 15 miles (24 km) long with a $1-million (equivalent to $8.88 million in 2023[30]) 880-foot (270 m) twin-span bridge over the Yadkin River. Construction on the bridge started in 1955 (this date is shown on a plaque, and most sources have used the date), but the lanes were not as wide as federal standards required, and the road had a sharp curve north of the bridge. Both of these characteristics saved money.[31]
The Federal-Aid Highway Act of 1956 provided for 90-percent federal funding of highways that would become part of the Interstate Highway System, and the North Carolina Highway Commission used the funds to build the rest of the highway, which opened as I-85 in 1958. The bridge, finished a year earlier, was grandfathered despite not meeting standards.[31]
Another section of I-85 opened to traffic on September 9, 1958, when an 11.3-mile (18.2 km) stretch in Mecklenburg County was opened.
The year 1960 saw several sections of the highway open to traffic:[28]
An 18.3-mile (29.5 km) section of I-85 between Henderson and the Virginia border as well as a 46-mile (74 km) section between Greensboro and western Durham opened to traffic.
A 15.4-mile (24.8 km) portion of US 29/US 70 between Salisbury and Greensboro was incorporated into I-85 when further grade separations and access control were completed.
A 14-mile (23 km) segment of I-85 known as the "Charlotte Bypass" in Charlotte.
A 13.8-mile (22.2 km) segment between Greensboro and Whitsett.
By 1965, I-85 from the South Carolina border to Charlotte was complete, while it took until 1970 for the section between Charlotte and Durham to be completed. However, the "Temporary 85" designation would remain on the segment between Lexington and Greensboro until 1984 because there were too many access roads. That year, a new six-lane section opened, resulting in the "Temporary 85" designation to be dropped.[32]
Since its completion, many widening projects have been undertaken on I-85, particularly along the stretch of highway between Gastonia and Durham. By 1988, widening I-85 to six lanes from Greensboro to Burlington was being considered.[33] The plan was later changed to eight lanes.[34] The $175-million (equivalent to $374 million in 2023[30]) project began in 1989. With the opening of a 2.3-mile (3.7 km) section in Alamance County on November 23, 1994, 21 miles (34 km) of I-85/I-40 were eight lanes. An additional 14 miles (23 km) were to be ready by 1996, giving the Interstate eight lanes all the way to where I-40 turned southward at Hillsborough.[35]
In addition, I-85 was relocated in 2004, south of Greensboro, forming part of the Greensboro Urban Loop, allowing through traffic to bypass that city's downtown area.[36] Between 2004 and 2008, I-85 was widened to eight lanes around Salisbury.[31]
The I-85 Corridor Improvement Project, located in Rowan and Davidson counties, was a two-phase project to replace the narrow bridge over the Yadkin River and widen the freeway from four to eight lanes.[37] In the first phase, all traffic from the old bridge moved to a new $201-million (equivalent to $264 million in 2023[30]) bridge in August 2012.[31] On March 9, 2013, all eight lanes of the I-85 bridge opened to the public.[38] The project finished eight months ahead of schedule and $44 million (equivalent to $57.7 million in 2023[30]) under budget.[39]
Following the completion of the widening of I-85 between exits 49 and 55, a new project was started to widen I-85 from exit 55 (NC 73) in Concord, Cabarrus County northward to exit 68 (NC 152) in China Grove, Rowan County. Like the prior project, I-85 is being doubled in capacity, expanding from two travel lanes in each direction to four travel lanes in each direction. The project is now complete as of May 2021. The first phase (from exit 55 to exit 63) began in early 2014, and the second phase (from exit 63 to exit 68) began in early 2017.[41] Construction is scheduled to be completed by December 2017.[42] When finished, that will leave I-85 in North Carolina with at least six lanes of highway between exits 10 (US 29 north/US 74—Kings Mountain and Shelby) and 164 (I-40 in Hillsborough).
There are four auxiliary routes and one business loop in the state. I-285 runs concurrently with US 52 connecting I-85 to I-40 in the Winston-Salem metropolitan area. I-485 forms a beltway around Charlotte, serving as a bypass for I-85 and I-77. I-785 serves as a spur route, forming a portion of the eastern part of the Greensboro Urban Loop. I-885 connects I-85 to I-40 in the Durham area.
