46-458: Interstate 485 ( I-485 ) is a 66.68-mile-long (107.31 km) auxiliary Interstate Highway encircling Charlotte, North Carolina . As a complete loop , it is primarily signed with "inner" and "outer" designations, though at some major interchanges, supplemental signage reflects the local compass orientation of the road. The entire route lies within Mecklenburg County . A beltway for

92-469: A Topgolf restaurant seen to the side. I-485 then curves left again and intersects NC 160 (Steele Creek Road), providing access to Charlotte Premium Outlets . Yet again, I-485 turns entirely north, exiting the suburban areas and entering some rural development. Crossing over the Piedmont rail line of Amtrak and a small stream, I-485 intersects with US 29 / US 74 (Wilkinson Boulevard), allowing entrance to

138-800: A clockwise direction around the city of Charlotte is on the "Inner" loop and traffic traveling in a counterclockwise direction is on the "Outer" loop. This system can be confusing, but it is logical; since traffic in the US generally travels on the right side of the road, the clockwise traveling lanes will always be the "Inner" lanes of a loop. There are three control cities along the route: Huntersville , Matthews , and Pineville . Secondary control cities, which include Spartanburg , Statesville , Greensboro , and Columbia , are also listed at various interchanges for travelers that want to bypass Charlotte to other destinations, via I-77 and I-85. I-485 in North Carolina

184-535: A groundbreaking near US 521 , marking the start of construction on the first 1.3-mile (2.1 km) section between US 521 and North Carolina Highway 51 (NC 51). Martin also announced the designation "Interstate 485" for what had previously been called the outerbelt. The section opened November 1, 1990, two months earlier than planned. A $ 67.2-million (equivalent to $ 125 million in 2023) 2.6-mile (4.2 km) section of I-485 from US 521 to I-77 opened October 24, 1994. The section included

230-513: A 2.3-mile (3.7 km) segment between I-85 (near Belmont) and NC 27 (Mount Holly Road) opened; signed as Future I-485, it was also dedicated as the Craig Lawing Freeway. Six months later, on May 9, 2007, another 1.5-mile (2.4 km) segment, between Mount Holly Road and NC 16 (Brookshire Boulevard) was opened. On December 4, 2008, a 5.5-mile (8.9 km) segment between Brookshire Boulevard and NC 115 (Old Statesville Road)

276-439: A 2000 policy that prevented the state using trust fund money, a major source of funding for new projects, to widen existing roads. Eventually, NCDOT was able to allocate new funds for a widening project, between US 521 (Johnston Road) and I-77/US 21, which was slated for construction in 2012. On November 18, 2011, NCDOT changed the plans with an extension of the widening project to Rea Road and additional space allocated for

322-581: A bit southeast and reaches a diverging diamond interchange with Mallard Creek Road, another one of Charlotte's main roads. It turns even more in a southeast direction and reaches a turbine interchange with I-85 once more. From the I-85 interchange, I-485 becomes the Governor James G. Martin Freeway , named after the former governor of North Carolina. The terrain of I-485 becomes a mixture of concrete and asphalt, and

368-565: A cost of $ 202.9 million, the 16.6-mile (26.7 km) I-485 Express Lanes project will establish new toll lanes along its entire planned route. It will also include the following improvements: adding additional general purpose lanes between Providence Road and Rea Road, extending auxiliary lanes between Independence Boulevard and East John Street, establishing dedicated connectors from the Express Lanes to Johnston Road (eastbound only) and Westinghouse Boulevard (westbound only), and incorporating

414-507: A feasibility study that would help improve traffic flow to I-485 and widen the northbound lanes on NC 16. I-485 then makes a gradual turn northeast, meeting another roundabout interchange with Oakdale Road, opened in 2017. Continuing through forest yet again, I-485 turns even further to the east and crosses the Long Creek two more times, then enters suburban areas and meets the western terminus of NC 24 (Harris Boulevard) at an interchange with

460-506: A few months later, on August 13, the segment was extended to NC 49 (University City Boulevard). In December 1999, the main section of I-485 continued its extension north from US 74 to Idlewild Road, adding 2.3 miles (3.7 km). In June 2000, another three-mile (4.8 km) extension was completed, between Idlewild Road and Lawyers Road in Mint Hill , at a cost of $ 10.2 million (equivalent to $ 17.2 million in 2023). In 2003,

506-513: A few years prior to the mall's opening. It has become the dominant retail destination for the thriving communities in North Charlotte and the Lake Norman region, from where it gets its name. It was announced in 2013 that Northlake Mall would receive Charlotte's second H&M store, after the recently announced store at Carolina Place Mall . These two stores, along with the planned store at

552-842: A four-level interchange, the first and only in North Carolina, at its junction with I-77. On December 9, 1994, the section from NC 51 to Rea Road opened. On July 1, 1997, a $ 13.9-million (equivalent to $ 24.5 million in 2023) two-mile (3.2 km) section of I-485 opened between I-77 and NC 49 , a section designated the Seddon "Rusty" Goode Jr. Freeway, named for a member of the North Carolina Board of Transportation who helped decide where I-485 would be built. On August 15, 1997, 2.3 miles (3.7 km) of I-485 opened between Rea Road and NC 16 (Providence Road). An $ 8.6-million (equivalent to $ 15.2 million in 2023) 1.4-mile (2.3 km) section from NC 49 to Brown-Grier Road in

598-567: A future toll lane to be constructed as well as extending the widening project towards Rea Road. The future toll lanes, when completed would be between US 74 (Independence Boulevard) and I-77/US 21; in April 2014, the Charlotte Regional Transportation Planning Organization (CRTPO) adopted the 2040 Metropolitan Transportation Plan (MTP), which included establishing toll lanes along I-485. The first segment of

644-733: A future toll lane, between Johnston Road and I-77/US 21. Construction on the modified widening project began in 2013; at a cost of $ 83.3 million (equivalent to $ 105 million in 2023), the 9.2-mile (14.8 km) widening project was completed in December 2015. On January 15, 2017, the Oakdale Road interchange (exit 18) was opened to traffic, existing previously as a graded future interchange since 2008. Since November 18, 2011, NCDOT has made plans for future toll lanes along I-485. Modifying an already planned widening project between US 521 (Johnston Road) and I-77/US 21, it called on

690-479: A mile after that by crossing the Clear Creek . Passing Idlewild Road, which underwent construction numerous times, I-485 turns southwest, and utilizes another partial cloverleaf interchange with US 74. The interchange ramps were closed as part of a project to build express lanes along I-485 on August 1, 2023. Several miles later, I-485 has a partial cloverleaf interchange with NC 16 (Providence Road) again, just outside

736-543: A north direction and intersecting NC 51 (Pineville-Matthews Road) at a partial cloverleaf interchange. A mile later, I-485 passes just south of the I-485/South Boulevard park and ride located off of South Boulevard at milemarker 65, as well as access to the President James K. Polk Historic Site . I-485 then continues northwest, crossing Sugar Creek , before reaching I-77/US 21 at a stack interchange , completing

782-419: A place where the highway mileage resets to zero. Beltways are also preceded by an even number in the first digit. Some examples of beltways include: Northlake Mall (Charlotte, North Carolina) In 2005, when Northlake Mall opened, it filled a void for the lack of retail in the northern portion of Mecklenburg County . A mall had been planned for this region for years, but plans never materialized until

828-496: A single cloverleaf, where drivers on NC 24 can access Northlake Mall . I-485 then turns slightly northeast, entering Huntersville , and crosses another small stream before making another curve back east, intersecting with I-77 again at a large interchange composed of partial cloverleaf and turbine interchange ramps. The segment of I-485 from here to I-85 is the latest segment of the Interstate, completed in 2015. I-485 also picks up

874-458: A state. There are three states that have no auxiliary Interstate Highways: Alaska, Arizona, and New Mexico. North Dakota has an auxiliary route, but it is unsigned , and Wyoming's does not meet Interstate Highway standards. Auxiliary Interstates are divided into three types: spur , loop , and bypass routes. The first digit of the three digits usually signifies whether a route is a bypass, spur, or beltway. The last two digits are derived from

920-605: A wildlife refuge and lake. I-485 then intersects a roundabout interchange with Moores Chapel Road, allowing drivers to reach the U.S. National Whitewater Center . The Interstate next meets NC 27 at a partial cloverleaf interchange for Mount Holly , then crosses the Long Creek, a tributary of the Catawba River . I-485 continues through forested land and near a dog park before utilizing another partial cloverleaf interchange with NC 16 (Brookshire Boulevard) for Newton at milemarker 16. The interchange as of 2018 has been undergoing

966-620: Is split into four dedicated or memorialized stretches of freeway: The first section of what became I-485 was completed around 1967, connecting a newly opened section of I-85 with US 29 near the Cabarrus – Mecklenburg county line. This section became a part of I-485 on May 5, 1999, the first section of the highway on the north end of the county. In 1975, planning began for the Charlotte outerbelt. On July 8, 1988, Governor James G. Martin and state transportation secretary Seddon Goode attended

1012-513: The Ballantyne neighborhood, where it travels entirely in a westward direction. It then enters suburban areas and receives the northern terminus of US 521 (Johnston Road) at milemarker 61. The express lanes in the future will connect Johnston Road directly to I-485, and vice versa. I-485 then turns a little northwest, crossing McAlpine Creek, another tributary of the Catawba River before turning in

1058-552: The Charlotte metropolitan area was first proposed in the mid-1970s, with the first section opening in 1990. The beltway was completed in stages over the next several decades, with completion of the last segment of the highway on June 5, 2015. All of I-485 is part of the National Highway System , a network of roads important for the nation's defense, economy, and mobility. Most of I-485 ranges from four to eight lanes wide, and

1104-589: The SouthPark Mall , would be the only H&M stores in the Charlotte area. In June 2014, it was announced that Taubman Centers would sell Northlake Mall to Starwood Capitol Group, as part of a portfolio of malls, for an aggregate purchase price for the portfolio of $ 1.4 billion. In February 2016, Starwood Capitol Group announced a $ 50 million expansion of the mall, adding an additional 200,000 square feet. Dick's Sporting Goods closed in February 2021, in favor of

1150-553: The Interstate passes through somewhat suburban areas, intersecting US 29 (North Tryon Street) a second time, providing access to Concord Mills and Charlotte Motor Speedway . I-485 then meets NC 49 (University City Boulevard) at a partial cloverleaf interchange also a mile later for the University of North Carolina at Charlotte . It passes underneath Lynx Blue Line and crosses the Back Creek as it yet again enters rural areas, going over

1196-571: The Reedy Creek and paralleling, later crossing the McKee Creek, both of them being tributaries of the Rocky River . From here, the terrain is entirely asphalt. I-485 then meets NC 24/NC 27 (Albemarle Road) a second time at a partial cloverleaf interchange. The Interstate intersects with NC 51 (Blair Road) a mile later near the town of Mint Hill . It turns entirely due south, then intersects NC 218

1242-464: The Steele Creek community opened in two stages August 26 and 27; the name of Brown-Grier Road changed to Arrowood Road when that road was extended. Seven more miles (11 km) opened September 15, connecting NC 16 to US 74 . In May 1999, the original segment between I-85 and US 29 (North Tryon Street) was widened and rebuilt to Interstate standards , officially becoming part of I-485;

1288-403: The beltway and resetting the mileage. Since I-485 is a beltway, the compass orientation of the freeway is not uniform around the loop. To remedy the uniformity issue, the inner–outer orientation system was implemented and became the primary method of signing the direction of travel around the loop. Some sections of the loop are signed with additional north–south or east/west labels (depending on

1334-470: The existing planned project of adding a new interchange at Weddington Road. Tolls would be collected using an electronic toll collection (ETC) system; drivers will need to have the NC Quick Pass , or other interoperable transponder, or will be billed by mail with a higher rate. Construction was slated to begin "tentatively" in mid-2018, and is currently still going on as of 2024. Milemarker numbering along

1380-623: The general direction of travel along a particular stretch) to aid drivers familiar with compass directions. Usually when both systems are utilized on signs, the compass directional banner is placed above the number shield and the inner/outer banner is placed below. Officials originally decided to use only "north" and "south" compass directions when signing the route, but, because this would be confusing with multiple "norths" and "souths", "inner" and "outer" designations were included. Although "east" and "west" signs exist, these were phased out in favor of "inner" and "outer" designations. Traffic traveling in

1426-535: The last 12.5 miles (20.1 km) needed to link main I-485 to its northern stub was completed, at a cost of $ 55.4 million (equivalent to $ 88 million in 2023). Opening in two phases, the first 7.5-mile (12.1 km) segment opened on September 3, 2003, between University City Boulevard and NC 27 (Albemarle Road); two months later, the second five-mile (8.0 km) segment opened on November 19, between Albemarle Road and Lawyers Road. On October 19, 2004, I-485

1472-483: The loop and providing a direct connection from I-77 near Huntersville to I-85 near Concord Mills. Since 2003, the North Carolina Department of Transportation (NCDOT) made sure that future segments of I-485 were designed with a minimum of six travel lanes. While the first segments of I-485 were already choked by traffic due to Charlotte's rapid growth, NCDOT could not immediately deal with the issue thanks to

1518-544: The loop freeway goes in a clockwise direction, beginning and ending at the interchange with I-77 / US 21 in southern Charlotte. The entire route is in Mecklenburg County . Auxiliary Interstate Highway Auxiliary Interstate Highways (also called three-digit Interstate Highways ) are a subset of highways within the United States' Interstate Highway System . The 323 auxiliary routes generally fall into three types: spur routes , which connect to or intersect

1564-550: The main Interstate Highway. For instance, I-115 contains an odd number in the first digit (1), which indicates that this freeway is a spur. The last two digits signify the highway's origin. In this case, the "15" in I-115 shows that it is a supplement to I-15 . Exceptions to the standard numbering guidelines exist for a number of reasons. In some cases, original routes were changed, extended, or abandoned, leaving discrepancies in

1610-522: The main terminal of Charlotte Douglas International Airport . At that same moment, I-485 immediately meets I-85 at a stack interchange . The lanes from I-485 to southbound I-85 are often congested due to them merging into one. North of the I-85 interchange, the naming of I-485 changes to the Craig Lawing Freeway , named after W. Craig Lawing , the former senator and politician of North Carolina. I-485 passes through more rural areas and just west of

1656-544: The name H. Allen Tate Jr. Highway , named after Allen Tate , the founder of Allen Tate Realtors . It immediately has a partial cloverleaf for NC 115 at exit 23C, which is proposed to undergo widening from I-485 to NC 24. The Interstate also passes above US 21 without direct access and then intersects a unique roundabout interchange with Benfield Road, Prosperity Church Road, and Prosperity Ridge Road; these three roads are all accessed via Robert Helms Road going inbound and Craven Thomas Road outbound respectively. I-485 then turns

1702-404: The new toll lanes, between Johnston Road and I-77/US 21, were completed in December 2015 but were not opened. The new unopen lanes along I-485 became controversial and discussions were made about making it a high-occupancy vehicle lane (HOV lane), or at least temporally; however, local and state officials said that could not be done and would cost more for just temporary use of the lanes. At

1748-542: The parent route at one end; bypasses , which connect to the parent route at both ends; and beltways , which form a circle that intersects the parent route at two locations. Some routes connect to the parent route at one end but to another route at the other end; some states treat these as spurs while others treat them as bypasses. Like the primary Interstate Highways , auxiliary highways meet Interstate Highway standards (with rare exceptions ). The shorter auxiliary routes branch from primary routes; their numbers are based on

1794-489: The parent route's number. All of the supplement routes for Interstate 95 (I-95) are designated with a three-digit number ending in "95": I-x95. With some exceptions, spur routes are numbered with an odd hundreds digit (such as I-395 ), while bypasses and beltways are numbered with an even hundreds digit (such as I-695 ). Because longer Interstates may have many such supplemental routes, the numbers can repeat from state to state along their route, but they will not repeat within

1840-415: The same Interstate, some states treat these as bypasses while others treat these as spurs—see Spur route above. A beltway (also known as a loop route ) completely surrounds a metropolitan city, and it is often connected with multiple junctions to other routes. Unlike other auxiliary Interstate Highways (and by extension, all primary Interstate Highways ), beltways do not have termini; however, they have

1886-503: The speed limit for the entire loop is 70 mph (110 km/h). The mileage begins at I-77 / US 21 in southern Charlotte, near the South Carolina state line. The southwestern segment of I-485 from here to I-85 is known as the Seddon "Rusty" Goode Jr. Freeway . Proceeding through, I-485 crosses I-77/US 21 on a pair of bridges connecting I-485 to I-77, and vice versa. Past the bridges,

1932-516: The system. In other cases, it may not be possible to use the proper number because the limited set of available numbers has been exhausted, causing a "non-standard" number to be used. A spur route 's number usually has an odd number for its first digit. It is usually one of the following: Examples include: Sometimes, a three-digit Interstate Highway branches off from another three-digit Interstate Highway. These spurs do not connect directly with their parent highways, but are associated with them via

1978-466: The terrain of the Interstate transitions from asphalt to concrete. Crossing Coffey Creek, a branch of Sugar Creek , I-485 passes through generally suburban development with trees lining the sides of the road. Shortly after, it meets NC 49 (South Tryon Street), one of the primary thoroughfares through Charlotte. The Interstate gradually makes a slight curve to the north and meets an interchange with Arrowood Road, another one of Charlotte's main streets, with

2024-472: The three-digit highways they do intersect with. Examples include: A bypass route may traverse around a city, or may run through it with the mainline bypassing. In a typical 3-digit Interstate Highway, bypasses usually have both its two termini junctioned with another Interstate highway. Bypass routes are preceded by an even number in the first digit. Examples include: In the case of an auxiliary Interstate highway which has both ends at Interstates but not

2070-623: Was opened; all future signage was removed from the previous segments, with new signage showing connection between I-77, toward Statesville, and I-85, toward Spartanburg. In 2011, West Boulevard interchange (exit 6) was opened to traffic, existing previously as a graded future interchange since 2004. The final segment, from I-77 to I-85 near the UNC Charlotte , had begun the right-of-way acquisition phase with contracts awarded in June 2010. The segment opened to traffic on June 5, 2015, finally completing

2116-479: Was widened, from four to six lanes between I-77/US 21 and Arrowood Road, and extended between Arrowood Road and I-85 (near Belmont). Completion of the $ 100-million (equivalent to $ 155 million in 2023) seven-mile (11 km) segment was noted that it would relieve traffic along the Billy Graham Parkway and provide an alternative route to Charlotte Douglas International Airport . On December 15, 2006,
