Springfield, IL – Commuters across central Illinois are facing hazardous driving conditions this morning as dense fog has formed east of Interstate 55, with the thickest concentrations near Interstate 57.
According to the National Weather Service (NWS) in Central Illinois, visibility has dropped to below one quarter mile in some areas. The fog is expected to persist through mid-morning, with gradual improvement likely after 9 a.m.
The advisory covers key travel routes including I-55, I-57, and surrounding county highways stretching from Springfield to Champaign, Decatur, and Mattoon. The reduced visibility poses a risk for morning commuters, school buses, and early freight traffic.
NWS officials caution drivers to slow down, allow extra space between vehicles, and use low-beam headlights if encountering fog. Visibility can change quickly over short distances, creating dangerous conditions, particularly in rural areas.
This morning’s fog comes as temperatures dip in the region, combining with calm winds and high humidity to create prime conditions for dense fog formation.
Travelers are urged to use caution until conditions improve later in the morning.
