Project Overview and Purpose

Planning and design efforts are underway to widen a 12-mile stretch of I-40 from Raleigh to the Cleveland School area (around N.C. 42) in Clayton. Work would improve the interstate by adding additional travel lanes to ease congestion and delays throughout the heavily traveled section.

Project Highlights

Proposed widening of I-40 would start at I-440 (Exit 301) in Raleigh and extend to N.C. 42 (Exit 312) in Clayton. Improvements would also be made to the I-40 and N.C. 42 interchange.

Environmental studies are underway and preliminary designs are nearing completion. NCDOT will hold a public meeting in 2017.

The project is being closely coordinated with the completion of the I-540 Outer Loop around the greater Raleigh metropolitan area.

Project History

NCDOT Public Hearing

The N.C. Department of Transportation held a public hearing in August 2014 to provide information about the design options under consideration for improving the interchange at I-40 and N.C. 42.

Earlier Planning Stages

On Oct. 13, 2009, NCDOT held a citizens informational workshop near the Cleveland School area in Clayton to obtain early public input on the project.

As design efforts began, a regulatory coordination meeting involving NCDOT and several state and federal agencies was held in Raleigh in 2011 to consider the purpose and need for the project, and to designate alternative design options. Follow-up meetings have been held with regulatory agencies, the City of Raleigh and the Town of Garner to determine design constraints and coordinate overlapping plans.

Resources for Local Property Owners

Although the N.C. Department of Transportation works to minimize the number of homes and businesses displaced by a road project, it is inevitable, in many cases, that a certain amount of private property is needed. The following information explains right of way acquisition and answers questions about the process.
