I-5506 Interchange Modifications


Under an on-call contract with NCDOT, Wetherill Engineering is providing planning, corridor modeling, NEPA documentation (Categorical Exclusion Document), public involvement, functional plans, preliminary design, and right of way plans for this interchange modification project. The purpose of the project is to eliminate the long queue extending out onto I-40, resulting from the heavy left-turn movement during peak periods at Aviation Parkway.

The project involves a new off-ramp and loop from I-40 westbound to Aviation Parkway southbound in the northwest quadrant of the existing interchange. The existing on-ramp from Aviation Parkway northbound to I-40 westbound will be relocated and lengthened to allow the proposed loop be constructed in the quadrant.

The project will also replace the existing bridge on Aviation Parkway over I-40, adding sidewalks and widening the new bridge. The I-40 westbound off-ramp terminal to Aviation Parkway will be modified to eliminate the left-turn movement to Aviation Parkway southbound.
