King County Road Services Division provides Road Alerts as a service to the public. While we try to provide accurate and timely information, estimates of the nature and duration of closures are subject to variables such as weather and traffic conditions that are beyond the control of King County and, therefore, difficult to predict. People relying on this information should do so at their own risk. Neither King County nor its employees or agents shall be liable for the accuracy of this information or any actions taken as a result.
