Road Alert: Important Update on Road Conditions in unincorporated King County

King County, Washington sent this bulletin at 12/15/2025 05:30 AM PST

It's Monday, Dec. 15 and some roads are opening and some areas are getting worse. Things are changing quickly, so please stay alert.

Heavy rain over the past week and a new atmospheric river is causing flooding and road closures across many parts of unincorporated King County and nearby state highways. In some areas, roads are starting to reopen, but in others, conditions are getting worse. Things are changing quickly, so please stay alert.

What you can do

Stay home if you can. It’s the safest option. If you must travel, plan for a longer commute and check conditions first:

Safety Reminders

Watch for slides. Look out for cracks in the ground, leaning trees, or bulging soil. Stay away and call 9-1-1.
Turn Around, Don’t Drown. Never drive through flooded roads. Water may be deeper than it looks and can hide damage.
Follow road and trail closures. Signs and barricades are there to protect you.
Drive carefully. Slow down and leave extra space between vehicles. Rain makes it harder to stop.

Our crews are ready to respond 24/7 to reports, closing unsafe areas, and clearing what they can as conditions allow.

If you see water over the road, signs of a slide, downed signs, or fallen trees blocking roads, call the 24/7 Road Helpline: 206-477-8100

If it is critical that you have more current information about the status of a road or a service request, please call 206-477-8100 or 800-527-6237. In major events, phone lines will be very busy and your patience is requested. Please do not e-mail for emergency road status information.

Please note that short-term road closures related to traffic collisions or utility work such as down powerlines are not reported via Road Alerts or My Commute as those closures are managed by outside agencies.
