Snow Removal Routes
Anti-Icing Treatment Routes

The Snohomish County Road Maintenance Division is responsible for approximately 1,584 total centerline miles of County maintained streets and roads across the county. In order to address resource constraints, and dispatch available resources where they are most needed during a major event, specific plowing and/or sanding routes are prioritized based on traffic volume (such as major arterial routes first), transit and school bus routes, terrain, and institutional knowledge of historical problem areas.

In the map at right, the following colors indicate the priority for snow and ice removal:
