​Project Overview
​​The proposed Complete 540 project, also known as the Southeast Extension, would extend the Triangle Expressway from the N.C. 55 Bypass in Apex to U.S. 64/U.S. 264 (I-87) in Knightdale, completing the 540 Outer Loop around the greater Raleigh area.
​​​Transportation, social and economic demands and mobility considerations are the basis for additional transportation infrastructure in southeastern Wake County. The Complete 540 project would link Apex, Cary, Clayton, Garner, Fuquay-Varina, Holly Springs and Raleigh. 

In addition to connecting several towns and cities, the project is expected to ease congestion on area roadways, including I-440, I-40, N.C. 42, N.C. 55 and Ten Ten Road.

Construction is likely to be completed in segments, and depending on available funding, each segment will likely have different construction timelines:

  • N.C. 55 Bypass to U.S. 401

  • U.S. 401 to I-40

  • I-40 to U.S. 64/264 Bypass (I-495)

Project Funding

Complete 540 is listed in the N.C. Department of Transportation's State Transportation Improvement Program as three projects:

  • R-2721 (N.C. 55 Bypass to U.S. 401)
  • R-2828 (U.S. 401 to I-40)
  • R-2829 (I-40 to U.S. 64/264 Bypass)

The estimated cost is approximately $2.2 billion and will be refined as development of the project progresses. The project is expected to be funded in phases.
