The N.C. Department of Transportation is widening 13 miles of I-40, from I-440 (exit 301) in Raleigh to Cornwallis Road (mile marker 314) in Clayton, by adding two lanes in each direction.
The project team is developing roadway designs and studying the designs' potential impact on the community and environment.
Construction started in fall 2018 and is scheduled to be completed late 2022.
A diverging diamond interchange will be added to the Jones Sausage Road (exit 303) interchange.
New flyover bridges at the I-40/I-440 interchange are scheduled to open in 2020.
I-40/N.C. 42 Interchange Upgrades
Improvements to the I-40/N.C. 42 interchange (exit 312) and surrounding network of roads (including Cleveland Road) in Johnston County will allow the area to better handle large volumes of traffic.
Construction of a diverging diamond interchange at I-40/N.C. 42 and an interchange at Cleveland Road began in summer 2020.
The project is being closely coordinated with the completion of the I-540 Outer Loop around the greater Raleigh metropolitan area.
