A Highway Advisory Radio (HAR) system was installed on I-90, Snoqualmie Pass to inform motorists of winter driving conditions. Despite numerous operational problems with equipment, the service has been well received by the traveling public. The system was found to have an added benefit during the summer months as an information system to alert motorists of delays or other problems caused by construction activities. The HAR system on Snoqualmie Pass has been expanded and additional systems have been installed in the Seattle area to inform motorists of construction activities.
