The route is posted by the Charlotte Department of Transportation (CDOT), using a modified pentagonal county road shield, with a green background and the city's crown logo above the number.

The few intersections on Billy Graham Parkway include a trumpet interchange with Josh Birmingham Parkway, the main access to Charlotte/Douglas International Airport, an intersection with West Boulevard (NC 160), and a partial cloverleaf interchange with Tyvola Road near Paul Buck Boulevard (near the former site of the Charlotte Coliseum).

Billy Graham Parkway ends at South Tryon Street (NC 49), where Route 4 continues east on Woodlawn Road.

Sugar Creek Road crosses North Tryon Street (US 29/NC 49) and then I-85 (Julius Chambers Highway) at exit 41, where Route 4 ends.

[8][9] The rest of the eastern half was finished in the late 1970s,[10] at which time the Charlotte DOT chose the "Route 4" label, in order to give the road one designation but avoid renaming the existing street names.

[5] The remainder of the loop was completed in 1981,[10] connecting to an existing I-85 interchange that served Mulberry Church Road,[8] and was named after Reverend Billy Graham, a Charlotte-born evangelist.

[12] The American Association of State Highway and Transportation Officials approved truncating US 521 to I-485, the new outer beltway, in May 2003,[13] making the entire length of Route 4 a secondary road.
