NCDOT to Build Diverging Diamond on I-40 at Airport Blvd

MORRISVILLE, N.C. – The North Carolina Department of Transportation believes it has the answer to the traffic issues on Interstate 40 at the Airport Boulevard interchange.

  • NC DOT to build diverging diamond interchange at Airport Boulevard and I-40

  • It will help drivers navigate increasing traffic

  • Work will being early in 2020 and last until 2023

The NCDOT is about to begin construction on the first diverging diamond interchange in the Triangle at the intersection. There are 13 of them in North Carolina.

It will help drivers navigate increasing traffic in the area.

According to the NCDOT website, “A Diverging Diamond interchange allows free-flowing turns when entering and exiting an interstate, eliminating the left turn against oncoming traffic and limiting the number of traffic signal phases. It is also easy to navigate, eliminates last-minute lane changes and provides better sight distance at turns, which results in fewer crashes. The design also reduces congestion and better moves high volumes of traffic without the need to increase the number of lanes in an interchange.”

Work on the interchange is expected to begin in the early part of 2020 and will be completed by 2023.
