Interstate 40 is a critical limited-access roadway that serves regional, statewide, and national purposes.  I-40 in the Triangle connects Hillsborough, Chapel Hill, Durham, Research Triangle Park, Morrisville, RDU Airport, Cary, Raleigh, Garner, and Benson with each other, with other communities in Orange, Durham, Wake and Johnston counties, and with the rest of North Carolina and the nation.

I-40 is the most heavily-traveled and congested highway in the region, with traffic counts of more than 140,000 vehicles per day near Research Triangle Park.  While the completion of the I-40 Cary/Raleigh widening in spring 2011 and the recent opening of the I-40/I-540 interchange improvements in fall 2010 are welcome news to area commuters, our growing region will require additional investments in the I-40 corridor if the “Triangle’s Main Street” will continue to be able to provide the safe and efficient mobility needed for our economic vitality and quality of life.

The I-40 Regional Partnership Initiative

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 the Interstate in the Triangle region.  Current objectives include improvements to I-40 interchanges including a possible ramp metering pilot, improvements to reliever routes such as NC 54 and US 70, and transit enhancements via a pilot Bus on Shoulder System (BOSS) project beginning in July 2012 on portions of I-40 in Durham County.

The Partnership held its first meeting in spring 2009 and has met periodically since that time.  The Regional Transportation Alliance (RTA)  coordinates the activities of the Partnership, and several RTA Focused, Accelerated, Simple and Timely (FAST) research program volunteers have provided ongoing assistance for the initiative.
