Winter Roads Maintenance

During snow events, crews work in 12-hour shifts around the clock to ensure the entire road system (5,100+ lane miles) is plowed. In fact, Public Works is responsible for the largest county road system in the State of Washington.

The Road Department has 36 snow plows/sanding trucks, 34 graders, and 4 deicing trucks. Spokane County crews work in 12-hour shifts around the clock to ensure the entire road system (5,100+ lane miles) is plowed.

For more information, go to the Snow Plow Activity  or call Spokane County Public Works at (509) 477-3600.
For emergency please dial 9-1-1.

  1. Priority System & Process

Spokane County's maintenance department provides snow and ice control for all county roads. Snow removal is organized by the following priority system:

Priority 1 - Major Arterials

Priority 2 - Secondary Arterials

Priority 3 - Residentials

Priority 4 - Not Plowed

When the roads are plowed, snow must be removed to the curb line to ensure mail delivery and that snow-melt or rain water can reach drains. Trucks providing traction sand (mixed with road salt and granular deicer) usually follow the plows. A liquid deicing solution instead of sand may be applied to the more heavily traveled arterials depending on weather conditions and temperatures. Liquid deicer is used to prevent the snow from bonding to the asphalt and it also helps to minimize the amount of dust particles in our air.
