Recent Progress
Stage 1: Crews have finished installing all of the noise wall panels, drainage trenches and access gates. Major construction completed in June 2009. Final construction of landscaping and roadside restoration will be done in Fall 2009 which will complete work on Stage 1 of the project. The WSDOT team continues to coordinate with neighbors in the form of e-mail, telephone, fliers, and on-site visits to answer questions about the project.
Stage 2: The design team completed 100 percent design for Wall 1-North, which will be constructed using a non-concrete product called Carsonite AcoustaShield. The project was advertised in June 2009 and awarded in July 2009 to Massana Construction, Inc. The team is continuing to coordinate with Sound Transit in regard to the planned North Link Light Rail line that will be constructed in the same area as the noise wall. The Construction of Wall 1-North is scheduled to begin in fall 2009. The WSDOT team will continue to coordinate with neighbors in the form of e-mail, telephone, fliers and on-site visits throughout the construction phase.

Environmental Impacts / Compliance
The project's resultant noise reduction is beneficial to the surrounding environment and communities.
During construction the contractor will install erosion control measures to contain sediment and debris at the construction site.
Street use permits and noise variances for night time work have been obtained from the City of Seattle for Stage 1. Night work is not anticipated for Stage 2, but street use permits will be required.
