Project Overview and Purpose
Improvements to I-440 – between just south of Walnut Street in Cary and north of Wade Avenue in Raleigh – are needed to improve traffic flow, access and efficiency along the roadway (referred to locally as the Raleigh Beltline).
Changes include widening I-440 from four to six lanes, replacing pavement and bridges and upgrading interchanges.
This segment has four through lanes and forms a "bottleneck" between the six through lanes at both ends, causing congestion, which is forecast to increase.
Built in the 1960s, it is also oldest section of I-440 and is in need of rehabilitation. The roadway and interchanges have substandard design elements, such as poor sight lines, narrow shoulders, narrow medians as well as short acceleration and deceleration lanes.
- Start Date: 2018
- Property Acquisition Start: 2018
- Estimated Cost: $475 million
- Project Number: U-2719
- Affected Counties: Wake
The N.C. Department of Transportation, in cooperation with the Federal Highway Administration, has completed an environmental assessment of the proposed improvements to I-440.
An Environmental Assessment, which contains a summary of the impacts and benefits associated with the preliminary project designs – referred to as detailed study alternatives – was signed June 26, 2017.
NCDOT then held an open house and public hearing on Aug. 8, 2017, to give the public the opportunity to ask questions about the project, and to comment on the design maps and environmental assessment.
The NCDOT project team will review all feedback and explore options to incorporate and address concerns where and when feasible.
