Interstate 85 and 40 - (North Carolina) Exits 143 to 152 North/Eastbound
1I-85 enters the state from Cherokee County, South Carolina near Grover in Cleveland County, an outer suburb of the Charlotte metropolitan area. After only a few miles, the highway enters Gaston County. Near Kings Mountain, I-85 turns from a northeast trajectory to an eastward one and goes through Gastonia, where it widens from four to six lanes. It stays at six lanes until it reaches Belmont, where the highway widens again to eight lanes.
The highway crosses the Catawba River as it enters Mecklenburg County, then interchanges with I-485 as it passes north of Charlotte-Douglas International Airport. After crossing I-485, it turns northeastward again, bypassing Uptown Charlotte to the west and north. While the route does not enter Uptown, several exits do provide access to the area. An interchange with Interstate 77 north of Uptown provides direct freeway access. The route through Charlotte traverses the northern portion of the city and is more suburban than urban in character, with light industry such as truck terminals, warehouses, small manufacturing facilities, and small office parks lining the highway. It also passes by the University City area and the University of North Carolina at Charlotte.
North of Charlotte, I-85 interchanges with I-485 a second time as it continues northeastward into Cabarrus County. In Concord, it passes through a dense commercial district and provides access to both Concord Mills shopping mall and Charlotte Motor Speedway, afterwards passing south and east of Kannapolis. As of February 2019, the highway between exit 58 (near Concord) and exit 68 near the Rowan County town of China Grove is being rebuilt and expanded from 4 lanes total (two in each direction) with no shoulders. When complete, the route will have 8 total lanes through to its junction with Business 85 south of Lexington.
Between Exits 96 and 102, the northbound and southbound lanes switch places. The southbound lane crosses over the northbound lane just before the northbound lane passes over a small bridge over Hamby Creek. East of the northbound overpass and southbound underpass with Squire Bowers Road, a pair of rest areas which contain the North Carolina Vietnam Veterans Memorial Park are entered from the right, but are still in the median. Only after the underpasses beneath Johnsontown Road does the northbound lane run over the southbound one returning to its proper location.
Approximately 70 miles (110 km) northeast of the Charlotte area is the Triad area, anchored by the cities of Winston-Salem, Greensboro and High Point. I-85 bypasses High Point and also largely bypasses Greensboro. Up until February 2004, I-85 went through the heart of Greensboro and joined Interstate 40 near downtown. Today, I-85 is routed along the Greensboro Urban Loop and meets I-40 east of downtown. Its former route is now known as Business 85.
