What You Can Do

  • Plan Ahead: Use alternative routes and allow extra travel time.
    • Weeknight Closures (Sept 3-6, 2024): If traveling eastbound from West Seattle on the West Seattle Bridge, you must either exit for SR 99 north towards downtown. From there, to reach I-5, head toward 1st Ave S to get to the Edgar Martinez Dr S freeway on-ramp.
