In early November 2012, a collision on southbound I-5 at South 320th Street near Federal Way, caused significant damage to an existing noise wall. As a result of the collision, seven panels were damaged beyond repair. In December 2013, we completed replacing the damaged section of wall.

Noise walls are designed to provide reduction in average background traffic noise for the residences located directly behind the wall.
