Project Facts
- Construction crews are building three new noise walls. Two are on the west side of the freeway and one is on the east. The first two stages were completed in 2005.
- Construction began in July 2008 and is scheduled to be complete by fall 2009.
- The noise reduction goal is to achieve at least a seven decibel (dBA) decrease along all frontline public spaces and ground-level residences. Note: A 10-dBA reduction in noise will sound half as loud to the human ear. For more info on acoustics and noise walls, visit WSDOT's Air Quality, Acoustics and Energy homepage. It also includes tips on how you can lower noise in and around your home.
November 2008
- This week construction crews will begin work on Wall E along Boylston Avenue E. between E. Hamlin and E. Roanoke streets.
- Parking on Boylston Avenue E. between E. Hamlin and E. Roanoke streets will be restricted until the project is complete. Crews have also temporarily restricted access to Boylston Avenue E. from E. Edgar Street for Wall E construction. Please use alternate routes.
- Crews are drilling shafts for the noise wall foundations on Wall D along Boylston Avenue E. between E. Lynn and E. Newton streets.
- Shaft work on Wall B along Harvard Avenue E. between E. Shelby and E. Hamlin streets is now complete and ready for noise panels to arrive.
Why is WSDOT
constructing noise walls in this area?
The Seattle neighborhoods of Roanoke Park and Eastlake experience high noise levels from I-5. The original construction of I-5 did not consider noise impacts at the time that it was built, so these neighborhoods are high priorities on the statewide retrofit list.
Noise walls are being designed and constructed to improve the noise environment both for residents and for outdoor enthusiasts. In addition, everyday activities like walking, gardening and barbeques will become more enjoyable.
The End Result
Installing noise walls along this busy corridor will noticeably reduce I-5-generated noise for the surrounding communities, improving outdoor public spaces and local resident/pedestrian life.
Project Benefits
Noise Reduction. The project will noticeably reduce freeway noise in the adjacent communities.
What is the project timeline?

- 2005: Completion of Stage 2 Boylston Avenue Wall and Harvard Avenue wall extension
- 2005-2007: Stage 3 Design
- Summer 2008 - Fall 2009: Stage 3 Construction
Public Involvement
Neighbors joined us for a construction information session (pdf 356 kb) in mid-July to learn more about:
Your thoughts and opinions are important to us. Send the project team an email if you would like to be added to the project mailing list. You will be kept posted via email on the project's status and on upcoming participation opportunities as the project progresses. You can also check this regularly updated project website for the latest information about the project.
Environmental Protection
The project's resultant noise reduction is beneficial to the surrounding environment and communities. Because the project limits fall along existing I-5 land area and structures, noise wall construction will not adversely affect the environment.

Services Web site for more information.
Increasing safety is one of our priorities
During the construction phase of this project, WSDOT will implement all necessary traffic management and safety measures.
Will this project impact tribal resources?
The limits of this project do not fall within tribal lands. At WSDOT we seek to address the concerns of the tribal nations using the process outlined in Section 106 of The National Historic Preservation Act and the WSDOT Tribal Consultation Policy adopted in 2003 by the Transportation Commission as part of the WSDOT Centennial Accord Plan.
