The Triangle Expressway is the largest highway project in North Carolina history and the first modern toll road in North Carolina. The first two segments opened in southern Durham and western Wake counties in 2011 and 2012.  

  • The first segment of the roadway in Research Triangle Park opened in December 2011.  
  • The next segments, representing the continuation of the 540 Outer Loop, opened in August and December 2012.  

The next extension of the turnpike (called the Triangle Expressway Southeast Extension) will extend the expressway from the N.C. 55 Bypass at Apex to the south and east to I-40 at the existing U.S. 70 Clayton Bypass.  

The final segment of the Triangle Expressway Southeast Extension will extend 540 from I-40 at U.S. 70 Clayton Bypass north and east to U.S. 64/264 freeway at I-540.

Complete 540 is proposed to be a 6-lane median-divided freeway.  Each direction would consist of three 12-foot lanes with an inner/outer 12-foot foot paved shoulder.  The two directions of traffic would be separated by a 70-foot median.




Complete 540 will be constructed as a design build project.  This is a different process than most typical roadway projects. The design-build process allows NCDOT to hire a team of designers and contractors that is responsible for the design, right of way acquisition, and construction of a project. The team may begin construction of one portion of the project while they finish the design and right of way acquisition for others, usually resulting in faster completion.

Other potential benefits to a design-build project may be innovative solutions and quicker resolution to problems that arise during design and construction.

NCDOT Resources for Property Owners

Although the N.C. Department of Transportation works to minimize the number of homes and businesses displaced by a road project, it is inevitable, in many cases, that a certain amount of private property is needed. The following information explains right of way acquisition and answers questions about the process.
