Project Overview and Purpose

The proposed project will improve traffic operations by providing an additional auxiliary lane (or lanes) to the exit ramp from I-540 to the westbound I-40. The proposed improvements to the exit ramp are considered necessary to accommodate traffic traveling along this section from west bound I-540 to west bound I-40.

Project Highlights

An environmental planning study is currently being conducted in compliance with the National Environmental Policy Act. The environmental compliance document is a Programmatic Categorical Exclusion (PCE), which is being prepared by the North Carolina Department of Transportation (NCDOT) and the Federal Highway Administration (FHWA), for the Northern Wake Freeway Interchange Improvements at I-540 and I-40.

The project is listed in the State Transportation Improvement Program (STIP) as project number R-2000AF, formerly identified as STIP project number I-5104.

The project limits extend approximately 2 miles, from the interchange of I-540 with Aviation Parkway (SR 3097) in Wake County to the interchange of I-40 with Page Road (SR 1973) in Durham County.
