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) and the Regional Transportation Alliance (RTA) business coalition, working in concert with other partners.

The I-40 Regional Partnership provides an ongoing focus on Interstate 40 in order to maintain and enhance its viability for travel and commerce, and to improve the travel experience on I-40 and core reliever/alternate routes.

Meredith McDiarmid, PE, NCDOT State ITS and Signals 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. You can download a one page overview of the I-40 Partnership here.
