Snow and Ice Information

The presence of the Chicago Department of Streets and Sanitation's blue Snow Fighting Trucks plowing and salting the city’s streets is an unmistakable sign that it is once again winter in the Chicago.

The Chicago Department of Streets and Sanitation is responsible for maintaining winter roadway safety on a route system of 4,100 miles. Our routes consist of city main streets, side streets and Lake Shore Drive. The expressway system that travels through Chicago is maintained by the State of Illinois' Department of Transportation, IDOT, and their familiar orange trucks.

Once on the roadways our trucks patrol, plow or salt our routes as necessary. When temperatures fall into the low teens, our trucks often spray our road salt with calcium chloride to make the salt work more effectively at lower temperatures.  

During a snow program the Chicago Department of Streets and Sanitation’s first priority is to clear our main routes and Lake Shore Drive. We will generally remain on these primary routes until a storm subsides. Once arterial streets are patrolled and deemed safe is generally when our crews move to the side streets.

While most side streets are cleared by full size Snow Fighting Trucks, Chicago's narrowest side streets are cleaned by a fleet ofsmaller plows. These include 4x4 pick up trucks with plows and Snow Tigers, which are narrow plows with heavy salt capacity

For major snowstorms, Streets and Sanitation also has the capacity to equip garbage trucks with "quick hitch" plows to supplement the fleet.  Since the garbage trucks don't have salt spreading capability, they run in tandem with trucks outfitted with salt spreaders.  

Snow Command Center

The Chicago Department of Streets and Sanitation coordinates Chicago's snow and ice control efforts from Snow Command located in the 911 Center on West Madison Street.

The high tech Command Center allows us to access and view more than 1,000 cameras and monitor our network of pavement sensors to get a quick and accurate assessment of our pavement conditions citywide. We track incoming weather systems via Doppler radar and through constant communication with our meteorological consultants and the National Weather Service. And we combine all of these technologies along with the Global Positioning Systems on all of our trucks to strategically deploy our snow personnel and our Snow Fighting Trucks.

Winter and Snow Parking Restrictions

In order to ensure that the most critical roadways in Chicago are kept open to full capacity at all times, the City of Chicago instituted and vigorously enforces a Winter Overnight Parking Ban on 107 miles of vital arterial streets from 3AM to 7AM between December 1 and April 1, regardless of snow.

Motorists who ignore this permanently posted seasonal tow zone face a $150 towing fee (minimum) in addition to a $60 ticket and an initial $10 daily storage fee.

A separate snow related parking ban exists for another 500 miles of main streets and can be activated after there are at least two inches of snow on the street, no matter the time of day or the calendar date. While the 2-inch snow ban is not activated often, motorists who are parked within the restricted area could receive a ticket or find that their vehicle has been relocated in order to facilitate snow clearing operations.

Both of these parking bans were implemented on designated arterial streets to prevent recurrences of problems that happened in 1967 and 1979 when Chicago came to a traffic standstill due to major snowstorms.
