Illinois commuters are being warned to prepare for potentially dangerous driving conditions on Wednesday, as freezing drizzle is expected to impact both morning and evening rush hours. The National Weather Service (NWS) has issued a special weather statement for central and northern parts of the state, including Chicago, Peoria, and Rockford, cautioning drivers about icy roads, slick sidewalks, and reduced visibility.
The freezing drizzle is forecasted to develop overnight on Tuesday and continue intermittently through much of Wednesday. Temperatures will hover around or below freezing during peak commuting hours, creating the perfect conditions for thin layers of ice to form on untreated roads and surfaces. Meteorologists warn that even light accumulations of ice—often referred to as a “glaze”—can significantly increase the risk of accidents on highways, overpasses, and bridges, where freezing tends to occur first.
Key Commuter Routes at Risk
The freezing drizzle could create hazardous travel conditions along major highways, including Interstates 55, 57, 74, and 94, as well as local roadways in urban centres like Chicago and Springfield. Bridges, overpasses, and exit ramps are particularly vulnerable due to their elevated exposure to cold air. Authorities advise motorists to reduce speeds, allow for extra braking distance, and be cautious on untreated side streets.
Public Transportation and Pedestrian Safety:
Those relying on public transit may face delays, and pedestrians are urged to exercise caution on icy sidewalks and stairs. Freezing drizzle could also cause minor disruptions at regional airports, with possible delays due to de-icing operations.
Precautions and Preparedness
The Illinois Department of Transportation (IDOT) has crews on standby to treat major roadways with salt and deicing chemicals, but the effectiveness of these treatments could be limited if precipitation persists throughout the day. Drivers are encouraged to check IDOT’s travel information services and local weather updates before heading out.
Officials remind residents to carry emergency supplies in their vehicles, including blankets, water, and flashlights, in case of unexpected delays.
