Interstate 285 (I-285) is a 23.49 mile longauxiliary interstate highway connecting the cities ofLexington andWinston-Salem, in the U.S. state ofNorth Carolina. The route was approved in February 2018 and was first signed in November 2018. Anauxiliary route ofI-85, it branches off of its parent route and runs northeast, bypassing central Lexington, before turning due north and heading toward Winston-Salem, terminating at an interchange withI-40. I-285 iscosigned withUS Highway 52 (US 52) for its entire route, and as of November 2018, still uses US 52 milemarkers and exit numbers. Other routes cosigned along parts of the route includeI-85 Business (I-85 Bus),US 29,US 70, andNorth Carolina Highway 8 (NC 8). I-285 has been approved for an extension along the US 52 freeway through Winston-Salem to meet the futureWinston-Salem Northern Beltway.
The southern terminus of I-285 is at the southwestern corner of the city of Lexington, at a partial interchange with I-85, with northbound-to-northbound and southbound-to-southbound the only possible movement; other directions require the use of surface streets in Lexington, using exit 84 (NC 47), the first exit on I-285. From the southern terminus, the route is also cosigned withUS 52,US 29,US 70, andI-85 Bus. The route follows the western boundary of Lexington's corporate limits, acting as a bypass of the city. Exit 85 is for Green Needles Road, while exit 86 provides access to Salisbury Road and Main Street, an old alignment of US 29/US 70. Exit 87 is a partial interchange and marks the northern end of the concurrency with I-85 Bus/US 29/US 70, which branch off to the northeast here. Exit 89 (US 64/Center Street) provides access for drivers heading from southbound I-85 Bus and northbound I-285, and vice-versa, as those movements are not covered at the direct interchange at exit 87. North of US 64, the route passes the communities ofBethesda andWelcome. At exit 89,NC 8 joins the freeway and the road turns from northeast to due north. The next interchange is exit 97 (Old US 52) which provides access to both Welcome and the community ofMidway. After exit 100 (Hickory Tree Road), I-285 enters the city ofWinston-Salem. Exit 103 is for South Main Street, and exit 105 is for Clemmonsville Road. The I-285 designation ends at exit 107 (I-40), though the freeway continues on as US 52/NC 8.
Approved by theAmerican Association of State Highway and Transportation Officials (AASHTO) in September 2005, after receiving an earlier approval from theFederal Highway Administration (FHWA) in July 2005, intending to provide anInterstate-quality freeway to connect Winston-Salem toCharlotte (via a portion of I-85). TheNorth Carolina Department of Transportation (NCDOT) installed "Future Interstate 285 Corridor" signs along the route in February 2006. The initial $2.5-million (equivalent to $3.43 million in 2024[3]) project to improve the roadway toInterstate standards was approved in October 2011.[4][5] With property acquisition already started in December 2012, cost estimates rose to $8.57 million (equivalent to $11.8 million in 2024[3]). The contract was awarded to J.T. Russell and Sons Inc. ofAlbemarle for $7.6 million (equivalent to $10.4 million in 2024[3]). Construction began in March 2014 and included reconstructing shoulders, improving drainage systems, resurfacing travel lanes, and realigning Marco Boulevard to accommodate a new southbound exit ramp alignment at Green Needles Road. In addition, crews resurfaced and preserved the bridges over Swearing Creek. The project was completed in late 2017.
On February 15, 2018, based on the completed improvements, the FHWA approved the I-285 signing between I-85 and I-40.[2][6] In November 2018, NCDOT placed I-285 ground-mounted route shields along the route from I-85 to I-40.[7][unreliable source?]
On May 20, 2019, AASHTO approved a request by NCDOT to establish Future I-285 north from its current northern terminus to a future I-74/I-274 interchangeWinston-Salem Northern Beltway. The justification for the 11.3-mile (18.2 km) extension was that Winston-Salem was a major transfer point for motor freight services and that numerous freight operators were already utilizing US 52 to access other major highways in and around the city; and that it would also serve the 330-acre (130 ha) Innovation Quarter, which will house research, business, and several college education facilities. The transition from future designation is dependent upon completion of the I-74/I-274 interchange and upgrades to interstate standards along the route.[8][9][10] Other plans include possible widening to six total lanes (three in each direction).[11]
Current exit numbers are based on US 52 mileage.
