Toll Highway


The 18.8-mile Triangle Expressway provides congestion relief on existing north-south routes serving the Research Triangle Park (RTP) region (including I-40) between Raleigh and Durham, as well as improves commuter mobility, accessibility and connectivity to the RTP employment center. The tolled highway comprises three sections:

  • Phase 1 - 2.8 miles of NC 540 from NC 54 to NC 55 near Morrisville, constructed by North Carolina DOT with Surface Transportation Program (STP) funds and opened to traffic in 2007 (but not tolled until August 2012), and 3.4 miles of NC 885 from I-40 south to the interchange with NC 540 (opened in December 2011 and tolled in January 2012)
  • Phase 2 - 6.6 miles of NC 540 from the southern terminus of Phase 1 at NC 55 to U.S. 64 (opened and tolled in August 2012)
  • Phase 3 - 6 miles of NC 540 from the southern terminus of Phase 2 at U.S. 64 to NC 55 Bypass near Holly Springs (opened in December 2012 and tolled in January 2013)
