Tunnel Lane Closures

Lane Closures in S. 188th Street Tunnel on February 20-21

As part of the Port of Seattle ongoing maintenance of its facilities, the westbound and eastbound left lanes in the S. 188th Street tunnel will be closed between the hours of 9:00 AM and 3:00 PM on Thursday and Friday, February 20 and 21. The closure is necessary to ensure the safety of the Port’s workers conducting a condition assessment of the center area of the tunnel. Based on the assessment, projects may be added to a list of improvements. Lighting has already been noted as a potential improvement project. The Port adjusted its hours of lane closure to help minimize impacts on morning and afternoon commute times. Thank you for your patience, and please drive carefully.
