Noise walls are free-standing barriers built adjacent to residential areas. They are typically made of concrete and exist to reduce traffic noise levels for people who live, work, and play near busy roadways.
Why is WSDOT
repairing a section of noise wall on southbound Interstate 5 near South 320th Street in Federal Way?
In early November 2012, a collision on southbound I-5 caused significant damage to the existing noise wall. As a result of the collision, seven panels were damaged beyond repair and needed to be removed.
Crews installed temporary wooden replacement panels in April 2013.
The End Result
This project will replace and repair a portion of damaged noise wall by installing seven new concrete panels.
The project will noticeably reduce freeway noise in the adjacent communities. Homes directly behind the wall will receive the greatest benefit.
