Noise Wall Replacement and Addition Near the I-495 Interchange
Construction of new ramps will require several sections of noise walls to be demolished and rebuilt in the northwest, northeast, and southeast quadrants of the I-495 Interchange. Additionally, a section of older wood noise wall along I-66 East between the ramp from I-495 North and Virginia Lane will be replaced toward the end of the project.
The project final noise analysis identified a section of new noise wall that will be built along I-66 West near the W&OD Trail and Idylwood Park.
