Our major routes are routinely patrolled and treated for snow and ice as necessary. In a snow emergency, road crews work around the clock in twelve hour shifts, keeping our nearly three hundred miles of roads open to the best of our ability.
If you don't see your road on the snow route map, it is most likely maintained by your city. Please note that we maintain no roads in the city of Portland.

All of our roads are designated Priority 1 or Priority 2.
Priority 1 roads are the arterial system roads. These are the most highly traveled roads, where schools, fire stations, hospitals and other emergency services are located.
These roads receive the first and highest level of service during a snow or ice event. They may be plowed, sanded, and treated with an anti-icing chemical.
Priority 2 roads are secondary roads. They will be plowed and sanded when resources become available, and when Priority 1 roads are deemed safe for travel. In severe storm conditions, this may not occur for two or three days.
In addition to plowing a road, we may sand or de-ice it.
We apply magnesium chloride as an anti-icing chemical. Mag chloride is an environmentally friendly product that helps us to maintain healthy rivers and streams.
On steep grades, intersections and corners, we may use a spreader sander mounted on a pickup or a dump truck to spread sanding rock, helping to improve traction.
