To reduce the impact of highway traffic noise on adjacent communities, more than seven miles of noise walls are proposed to be built along the project corridor. Per the Federal Highway Administration (FHWA) and Virginia Department of Transportation (VDOT) requirements, proposed noise walls must be warranted, feasible and reasonable.
In September 2016, during the project's preliminary engineering phase, VDOT completed a Preliminary Noise Analysis. In 2019, the Design-Build team updated and finalized the noise analysis based on the amended road design, additional field data, updated traffic studies and more detailed topographical data. The Final Noise Analysis was reviewed and approved by VDOT and FHWA, and proposed noise wall locations are shown on the project's interactive map.
In early 2020, VDOT will send letters to benefited parcel owners and tenants. The letter will request the parcel owner's or tenant's "Yes" or "No" vote on the proposed noise wall or series of walls that provide a noise reduction on their parcel. Noise walls receiving at least 50% of affirmative votes based on the responses received will be incorporated into the project's construction plans.
Noise walls as part of the Route 7 Corridor Improvements Project will be constructed from concrete posts and panels, and the side facing the road will have an ashlar stone pattern with a Virginia Dogwood border along the top (see rendering below). The residential side will have a full-height ashlar stone pattern.
