Ever-changing Weather Systems Require
Main streets, or most streets with stripes, are the priority for Denver Public Works' large plows. These are the streets that carry most of the city's traffic, as well as emergency vehicles and public transportation.
In addition to plowing the main streets, Denver frequently uses a dry deicing material to add traction to the roadways and help break up snow and ice. Denver uses another material called liquid magnesium chloride, particularly Downtown, in support of air quality efforts. The number of plows deployed and use of de-icing materials depends on the weather conditions.
During major snow events when Denver receives 12 inches or more of snow accompanied by prolonged freezing temperatures, 4x4 plows may be deployed to simultaneously clear residential, or neighborhood, streets.
