Road Services - Frequently-asked questions about Road Alert

What is King County Road Alert?
King County Road Alert is a Web-based e-mail subscription service designed to notify residents and motorists about road closures or hazardous travel conditions that have a significant impact on travel in unincorporated areas of the county. This information, provided by the Road Services Division, enables motorists to make informed travel decisions benefiting both themselves and the region by reducing traffic impacts.

The travel advisories provided by King County Road Alert have now been incorporated into the My Commute Map. Previously this information was available as a text list.

Road Alert travel advisories include information about closures or traffic problems that impact a specific road or major traffic corridor. Most county roads are closed due to construction activity, weather events or other unanticipated incidents. Subscribers will also be kept informed of the status of the closure and when the road is expected to reopen.

Traffic problems resulting from an accident and having a significant impact on the peak commute hours may be sent out in an alert — if information can be provided in a timely manner. You are advised to listen to radio traffic advisories for real-time traffic information.

If you have any questions or comments about Road Alert, please e-mail us.

Why don’t you put out Road Alerts when an accident or other emergency has closed a road?
While the Road Services Division makes every attempt to provide timely information about road closures, the notifications are not real-time. Information is first gathered from crews out in the field and limits of the closure are confirmed prior to being posted on the Web. By the time this procedure has taken place, most short-term closures have already re-opened.
What information does Road Alert provide via RSS?
Road Alert uses RSS to deliver the location and status of road closures or hazardous travel conditions that have a significant impact on travel in unincorporated areas of King County. By monitoring Road Alert RSS feeds, subscribers stay informed of the status of closures and anticipated reopenings.
