North Carolina Highway 51 is a primary state highway in the state of North Carolina. Entirely in Mecklenburg County, it runs from the South Carolina state line, in Pineville, to Mint Hill.

Route description[edit]

Though NC 51 begins at the state line, SC 51 is a short 1-mile (1.6 km) road that connects with US 21 near Fort Mill. Crossing the state line, NC 51 quickly becomes a 4-lane road as it goes through the town of Pineville. After its first intersection with Interstate 485, it enters the Charlotte city limits. In Charlotte, NC 51 crosses the busy intersections of Johnston Road and Providence Road, known for rush-hour traffic during the weekdays. In Matthews, NC 51 bypasses the main downtown area, followed by a semi-controlled interchanged with US 74 (Independence Boulevard). As the NC 51 enters Mint Hill, the road narrows to 2-lane. NC 51 crosses intersects with Interstate 485 again, before ending at NC 24/NC 27 (Albemarle Road).[2]

Junction list[edit]

The entire route is in Mecklenburg County.

  • 1920s: NC 51 is a state highway going from Rockingham to Ellerbe.[3]
  • 1935: NC 51 is renumbered NC 73 and NC 109 and a new NC 51 forms at US 521 in Pineville going to NC 24/NC 27 north of Mint Hill. This used to be NC 276, which was decommissioned after the introduction of US 276 in North Carolina.[3]
  • 1968: US 21 is moved onto I-77 allowing NC 51 to be expanded 2-mile (3.2 km) to the South Carolina border, from where it goes on to the new US 21.[3]
  • 1988: The first segment of NC 51 becomes a four-lane highway, at the Providence Road interchange.[3]
  • 1990: More widening makes NC 51 a four-lane road from Pineville to Matthews.[3]
  • 1991: Head-on parking in west Pineville is changed to parallel parking, allowing for NC 51 to be four lanes through that section of town.[3]
  • 1992-1994: With the last true center of congestion being downtown Matthews, Matthews Township Parkway is built, creating a bypass north of the city. NC 51 has not been rerouted or widened since, although many construction jobs have added turn lanes on the route.[3]
  • 1998: Interstate 485 opens in Pineville.[3]
