Toll Highway


The proposed 18.8-mile Triangle Parkway will provide near-term congestion relief on existing north-south routes serving the Research Triangle Park (RTP) region (including I-40) between Raleigh and Durham, as well as improve commuter mobility, accessibility and connectivity to the RTP employment center. The proposed tolled highway is comprised of three sections:

  • Triangle Parkway will extend from NC 147 at I-40 south 3.4 miles, terminating at the interchange with the Outer Wake Expressway.
  • Northern Wake Expressway (NC 540) is the portion of the Outer Wake Expressway that extends from NC 54 to NC 55. This 2.8-mile-long segment, which recently opened to traffic and was constructed by North Carolina DOT with STIP funds, is being transferred to NCTA in support of the project. This section will enable Triangle Parkway and Western Wake Freeway to function as a contiguous toll facility.
  • Western Wake Freeway connects with Northern Wake Expressway and will extend from a northern junction with NC 55 near Research Triangle Park to a southern junction with NC 55 Bypass near Holly Springs, covering a distance of 12.6 miles.
