Seattle employs 35 total snow plows, which largely prioritize transit and emergency routes, freeways, and the downtown area. Most major roads are plowed every three or more hours by crews working around the clock. That includes major highways like I-5 and I-90.
More remote areas and side streets — particularly in residential areas — tend to not be prioritized, although the city’s Storm Response Map shows that there are “planned response routes” for future treatment and plowing on most of these roads.
Outside of Seattle, the Washington State Department of Transportation has its own response plan to clear snow off highways and major commuter routes, employing approximately 500 snow plows and dump trucks. Those vehicles cover more than 20,000 miles of lanes.
