Forecasters warned residents of freezing rain and dangerous weather conditions throughout the Metro-east that were expected to affect the area from Wednesday morning through Thursday morning.
The National Weather Service in St. Louis issued a Winter Weather Advisory for Wednesday and Thursday warning of icy roads, freezing rain and slippery conditions.
KMOV reported a crash just before 7:30 a.m. in Madison County on Chain of Rocks Bridge, which was causing significant back ups for drivers approaching the bridge.
Another three-vehicle crash happened on an iced-over Eads Bridge about 6:30 a.m. KMOV reported the bridge was then closed in both directions for about an hour due to icy road conditions. It was reopened by 8:25 a.m.
The advisory was issued for Wednesday morning until 9 a.m. and will begin again at 6 p.m. until noon on Thursday.
"The ice will result in very slippery conditions on sidewalks, roads and bridges, including during the morning commute on Thursday," the advisory said.
Freezing rain continued in the area throughout Wednesday morning and was expected to stop by early afternoon. Another round of rain was expected to start Wednesday evening, according to meteorologist Doug Tilly.
"Temperatures will be slightly warmer so there are better chances the rain won't start until midnight and will continue overnight. Precipitation will be kind of light, a light glazing is all that we're expecting over there," he said.
Tilly said the road conditions will also depend on when roads are treated and when the rainfall begins. He said it is difficult to treat the roads properly when it is raining. The good news, however, is temperatures may stay high enough to stop freezing rain and melt any ice that has accumulated.
"We're not expecting a big ice storm at this point," he said.
The Illinois Department of Transportation, District 8, said their trucks were still treating roads in the area.
"Areas north of Metro East hardest hit. However, scattered slick spots are possible everywhere. Please use extra caution on the roads today," a tweet from the department read.
Additional precipitation accumulations of one tenth of an inch were expected throughout Wednesday, resulting in a a total accumulation of a tenth of an inch.
