'Diamond' traffic pattern coming to I-40 Airport Blvd exit

MORRISVILLE, N.C. (WTVD) -- A brand new traffic pattern is coming to the I-40 and Airport Boulevard interchange.

It shows what's called a diverging diamond interchange, and it will replace the Airport Boulevard bridge over I-40.

Drivers will cross to the left side of the road, which is supposed to allow a lot of cars to quickly move through intersections without having to add extra lanes and traffic signals.
