When winter storms hit, road crews are on the road day and night clearing snow and spreading salt until all roads are cleared. Snowplow drivers will often work around the clock fighting back hazardous road conditions.
During storms, major streets and thoroughfares are cleared first, along with bridges, school zones, hills, and steep incline areas (including those in residential areas). After that, residential neighborhoods with more flat terrain receive attention.
Continuing snow and wind, extremely low temperatures, and ice that intermittently melts and freezes can prolong the time it takes for an operator to complete a route.
