I-3306A: I-40 Widening - Orange County
I-3306A: I-40 Widening - Orange County
The N.C. Department of Transportation is proposing the widening of 11.4 miles of I-40 between I-85 and the Durham County Line in Orange County. The interstate would be widened by one lane in each direction to bring the highway up to three lanes each way, improving traffic flow along that corridor and helping relieve heavy congestion that develops during commuter times. The project would also improve the N.C. 86 exit and sections of that highway for several hundred feet both north and south of the interchange.
The purpose of the proposed project is to relieve peak hour congestion on this facility such that a level of service (LOS) D or better can be maintained for the 2040 build condition. Other desired outcomes would be to improve the traffic flow and continuity between the existing eight-lane section at the beginning of the project (I-85) and the six-lane section at the end of the project (Durham County Line).
Improving travel conditions on I-40 to a Level of Service “D” or better throughout this portion of the freeway from I-85 to the Durham County Line, will have a direct and positive impact on traffic flow and continuity experienced by the public using this corridor. Daily commuting between points west of I-85 and U.S. 15-501 should also experience fewer delays.
The I-3306A project has now been divided into three different sections as described below:
- I-3306AA: Widening of I-40 from I-85 to NC 86
- I-3306AB: Widening of I-40 from NC 86 to the Durham County Line
- I-3306AC: I-40 at NC 86 Interchange Improvements
During planning and design for highway projects, NCDOT must identify traffic noise impacts, examine potential noise abatement, incorporate feasible and reasonable noise abatement measures, and coordinate with local officials to provide helpful information on compatible land use planning and control. The procedures for doing this are stipulated by Federal regulation (23 CFR 772) and the NCDOT Traffic Noise Policy.
NCDOT has performed preliminary noise analyses for this project and an initial Traffic Noise Report has been prepared. In this study, noise walls were evaluated at 16 locations along the I-3306A project. Of these, 4 preliminarily meet feasibility and reasonableness criteria. These 4 locations are shown in red hatching as potential noise abatement areas on the updated public hearing maps shown below. As part of the project’s final design activities, additional noise studies will be conducted to identify recommended noise wall locations.
Once recommended noise wall locations are identified during final design, all property owners and tenants who are benefitted by a wall will be asked to vote on the wall. At that time, NCDOT will contact property owners and tenants who are eligible to vote and explain the balloting process and what they are being asked to vote on. Only recommended noise walls that pass this voting process will be constructed.
An important concept in Federal regulation and in the NCDOT Traffic Noise Policy is the Date of Public Knowledge, which stipulates when NCDOT is and is not responsible for providing noise abatement. The Date of Public Knowledge of the location and potential noise impacts for this project will be the approval date of the Categorical Exclusion (CE). The CE was approved on March 29, 2019. NCDOT is not responsible for evaluating or implementing any noise walls to protect developed lands that did not have building permits issued before the Date of Public Knowledge. NCDOT advocates use of local government authority to regulate land development, planning, design and construction in such a way that noise impacts are minimized.

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.
