What this record covers

Active Greenwood Road–U.S. 21 construction; exclude R-2307A from this status.

WHAT TO WATCH NEXT

Next agency construction update or confirmed traffic-stage change

Not yet confirmed

Timing remains subject to source confirmation and delivery conditions.

What remains uncertain

  • No opening date is established by the reviewed October update.
  • The overview and STIP differ on cost and mileage. Agency clarification is needed before adopting one current cost or length; no cause for the difference has been verified.

What is documented

  • Verified fact

    The October 2026 agency update describes drainage, weather-dependent paving east of I-77, retaining walls and bridge work. [9]

    Supports the stated scope; does not guarantee delivery. Evidence date: October 2026.

  • Verified fact

    The corridor design widens Greenwood–Perth from two to four lanes, and Perth–U.S. 21 from four to six. [3]

    Documented statement; verification does not guarantee delivery. Evidence date: January 2026.

  • Verified fact

    R-2307A and the active R-2307B scope must be distinguished. [1] [3]

    Documented statement; verification does not guarantee delivery. Evidence date: January 2026.

  • Verified fact

    The older NCDOT overview gives 5.5 miles and $249 million. January 2026 STIP R-2307B lists 6.9 miles and $289.272 million. The undated contractor description also gives approximately 5.5 miles. These are source-specific figures, not a reconciled current total. [1] [3] [12]

    Accounting and scope differences remain unresolved. Do not describe this as a verified cost overrun.

Why it matters

Reasonable inference

Lane and intersection changes can alter everyday routes and business access. Parcel access requires its own check. [9]
