Interstate 40 is a major east-west Interstate highway running through North Carolina. Nationally, it runs from Barstow, California to Wilmington, North Carolina. Locally, it is considered the Triangle's "main street", connecting the cities of Raleigh and Durham and the towns of Cary and Chapel Hill to Research Triangle Park, Raleigh-Durham International Airport, the coastal portion of North Carolina, and the Blue Ridge Mountains. It is signed as the Dan K. Moore Freeway between Durham and Cary and as the Tom Bradshaw Freeway within the Raleigh city limits.

In late 2018, work has begun on widening a twelve-mile stretch of I-40 between I-440 in Raleigh and NC 42 near Clayton in Wake and Johnston Counties. Intended to alleviate traffic congestion caused by the rapid growth of Clayton and the US 70 Clayton Bypass, the project adds two lanes in both directions and redesigns the interchange with NC 42 into a diverging diamond interchange, one of several planned for the Triangle. Work is scheduled to be completed in 2022.
Projects to improve two interchanges near Raleigh-Durham International Airport began in 2018 at Aviation Parkway. The improvements include adding a loop ramp from I-40 westbound to Aviation Parkway and replacing the bridge carrying the parkway across I-40. The improvements at Airport Boulevard will redesign the existing interchange into a diverging diamond interchange. The project will also add auxiliary lanes between Aviation Parkway and I-540.
In May 2019, the North Carolina Department of Transportation held a public meeting regarding current and upcoming road improvement projects in Raleigh and surrounding municipalities. One of the projects will upgrade the interchange between I-40, I-440, US 1, and US 64 in southwest Raleigh and the Walnut Street interchange near the Crossroads shopping center in Cary. The $151 million project resolves to create a less confusing and dangerous freeway and separate Interstate traffic from local mall traffic. Construction will begin in 2022.
Also in 2022, NCDOT will widen a four-mile stretch of I-40 from I-440, US 1, and US 64 to Lake Wheeler Road with the addition of one lane in both directions. The project is expected to cost $27 million.
