Chicago Snow Command closely monitors incoming weather systems and deploys our main fleet of 274 snow trucks. Once on the roadways, trucks patrol, plow, and salt the city’s streets. When the arterial streets are deemed safe for travel during or after a snowfall, the City’s salt trucks are dispatched to secondary, residential streets for salting and plowing operations.  Streets with hospitals and schools are given higher priority as well. This work continues until all city streets have been treated. When temperatures fall into the teens, the trucks often spray our road salt with calcium chloride to make the salt work more effectively at lower temperatures.  The Department of Streets and Sanitation has also been making frequent use of more environmentally friendly deicers that are made with salt water, sugar beet byproducts and calcium chloride. When time and breaks in the weather permit, they will apply this pre-treatment to our bridge decks and overpasses to slow down the formation of ice on driving surfaces.

For major snowstorms, the Department of Streets and Sanitation also has the capacity to equip between 150 and 200 garbage trucks with “quick hitch” plows to supplement the fleet. Since these don’t have salt spreading capability, they are run in tandem with trucks that do.

The City of Chicago does not plow alleys.
