Wake County, N.C.


The purpose of this project is to improve I-40 from I-440/US 64 (Exit 301) to just north of SR 1525 (Cornwallis Road) including improvements to NC 42 and SR 1010 (Cleveland Road). Once completed, this project will help reduce congestion on I-40, improve access to and from I-40, I-440 and six interchanges including US 70 Business, US 70 Bypass and NC-42. This project incorporates a Diverging Diamond Interchange (DDI) at NC 42 which will greatly alleviate traffic congestion in the area once traveling motorists get accustomed to the unique design.
