II-40-Regional-Partnership-logonterstate 40, the “Triangle’s Main Street”, is a critical limited-access roadway that connects Orange, Durham, Wake and Johnston counties with the rest of North Carolina and the nation.

The I-40 Regional Partnership is a cooperative initiative of the NC Department of Transportation (NCDOT), the Regional Transportation Alliance (RTA) business coalition, and other local, regional, statewide, and federal partners. The Partnership provides an ongoing focus on Interstate 40 in order to maintain and enhance its viability for travel and commerce.

The I-40 Regional Partnership initiative is designed to help participants discover, share, and examine the current status of Interstate 40 in the Triangle in order to identify both short- and long-term opportunities for improvements to I-40 in the Triangle region along with its interchanges, connecting freeways, and primary reliever routes.

Meredith McDiarmid, PE, NCDOT State Systems Operations Engineer, serves as the I-40 Regional Partnership executive. The Partnership held its first meeting in spring 2009 and has met at least annually since that time.
