About the Project

Noise Walls

To lessen the impact of highway traffic noise on adjacent communities, noise walls will be constructed or replaced at select locations on I-66 East and West between the Dulles Connector Road and Fairfax Drive/Glebe Road (Exit 71).  Noise wall eligibility is based on Federal Highway Administration (FHWA) and Virginia Department of Transportation (VDOT) criteria.  Multiple factors determine whether noise walls are feasible and reasonable and where they will be installed, including noise analyses, design plans, and traffic studies.  Learn more about Virginia’s State Noise Abatement Policy and noise walls here

Existing Noise Walls

If your community has a noise wall today, it will have one in the future. Existing dilapidated noise walls within the project limits will be replaced with new noise walls. Replacement walls will be the same height or higher than existing walls. When a noise wall is removed, work will continue until replacement.  New noise walls will have a simulated stacked stone façade on both the roadway and residential sides, and will closely match the existing concrete noise barrier on I-66 West between the Washington Boulevard on-ramp and the Dulles Connector Road (shown in the photo above).

New Noise Walls

Benefitted property owners (and tenants where appropriate) were mailed letters and ballots from VDOT in early February 2019 with instructions for voting. If the majority votes in favor of the noise wall, then the noise wall will be incorporated into project design plans. This presentation provides background information on noise walls, the voting process, and locations identified as eligible for new noise wall.

Final Noise Analysis Report

The project team conducted a noise analysis of the final project design to determine whether new noise walls were feasible and reasonable.  Find a copy of the report here

The final noise analysis report includes map diagrams showing property-level detail and proposed noise wall locations.
