An overturned semi truck was the result of one of dozens of crashes across the Kansas City metro area on Friday after sleet and freezing rain made for icy roads.

According to the Missouri Department of Transportation traveler map, most of Kansas City area highways were either covered or partly covered in ice and snow — a trend that appeared throughout most of the northern third of the state.

According to a tweet from MoDOT about 8 a.m., northbound Interstate 435 was closed at I-35 for an overturned semi. Missouri State Highway Patrol Troop A tweeted that the semi was blocking all lanes and traffic was being diverted to Highway 69. The northbound lane of I-435 opened back up around after 10 a.m.

In Lee’s Summit, a semi was in the grassy median near Highway 50 and Todd George Road.

In the Northland, one lane of northbound Highway 169 was closed after multiple vehicles crashed. And on southbound I-635 just past I-29, two vehicles crashed, closing the left lane.

MoDOT also tweeted that two snow plows and a motor carrier vehicle were rear-ended Friday morning.
