Road Closure Request - Seatac S 188th Street

I am the contractor for the S. 188th Street Tunnel Improvements project for the Port of Seattle. We are closing S 188th St. Tunnel from 8:00 P.M. - 5:00 A.M. nightly from 11/17/2025 to the morning of 11/24/2025 between 16th Ave South and 28th Ave South.

Thanks for the information. I have added the closure.

In the future, post in the Washington section of the forum for best response.
