Morrison Bridge inspection requires overnight lane closures on I-5

Nov. 6, 2025

PORTLAND – Expect lane closures on southbound Interstate 5 under the Morrison Bridge after midnight tonight for concrete inspection.

Starting at 2 a.m. Friday, up to two lanes will be closed so that bridge crews can inspect the underside of the concrete structure. We expect to complete the inspections and lane closures by 5 a.m. Friday.

If you are traveling southbound I-5 through Portland in the early hours Friday, please slow down and give space to road crews and equipment for your safety and theirs.

Also tonight, both directions of I-5 in southwest Portland will be closed for RealTime sign installation. The interstate will be closed from 11 p.m. today to 5 a.m. Friday between Interstate 405 and SW Terwilliger Boulevard.
