Busy Johnston County Route Undergoing Changes

GARNER – Changes are coming to how traffic moves in a commercially congested area of N.C. 42 south of Garner.

The changes will affect some of the N.C. 42 intersections on the west side of Interstate 40's Exit 312.

Today, a new traffic signal at Technology Drive and N.C. 42 has been set to yellow-flashing mode, and it will become active April 3. (This change had been scheduled for March 27, but rain and other factors required the contractor to reschedule the change to April 3.) 

The existing traffic light where Commerce Parkway/Glen Road intersect N.C. 42 will be removed on the evening of April 3, effecting the following traffic changes:

  • Commerce Parkway will become what is known as a “right in, right out," which means eastbound drivers on N.C. 42 will be able to turn right at this location, and drivers exiting Commerce Parkway will be redirected to turn right onto the highway;
  • Westbound drivers on N.C. 42 will be able to turn right into Glen Road. However, drivers on Glen Road will lose access to N.C. 42; instead, they will use a new roundabout at Technology Drive, then its new traffic signal on N.C. 42.

Additionally, a temporary median will be installed next week along N.C. 42 between Technology Drive and Interstate 40 restricting left-hand turns. A raised, concrete median will be constructed along this same stretch in the coming months. 

These changes will improve safety and ease congestion in a design referred to as a reduced conflict intersection.

All of this work is part of the ongoing project to widen I-40 from Exit 301 to mile marker 314, as this project webpage​ by the N.C. Department of Transportation explains. The project website includes this online map showing details of the changes to Exit 312 and N.C. 42.
