Noise Wall Location

Noise Wall: I-5 Southbound E Edgar St to E Gwinn Pl

Beginning in Q4 2023/Q1 2024, WSDOT will build a noise wall along southbound I-5. The noise wall will begin just north of Edgar St and continue along SB I-5 to Franklin Ave E.

Why we are doing this work:

• Some homes stand within 100 feet of the busiest highway in the state.

• Building this noise wall will help abate express lane noise to the nearby neighborhood.

• Especially helpful during rush hour when the express lanes have more traffic and when we need to keep the express lanes open overnight.

What to expect:

• Anticipated duration: 1 year

• New facilities: One noise wall

• Nighttime and weekend closures of:

  • SB I-5 off- and on-ramp to NE 50th.

  • Single and double lanes of SB I-5.

  • SB I-5 off-ramp to Boylston Ave E.

• Nighttime and daytime closures of:

  • Boylston Ave E throughout the project.

Winter 2023: Construction scheduled to begin
