A nine-vehicle crash happened in Negaunee Township on US-41 shortly after 12 p.m. on Monday. One vehicle involved was an ambulance.
13 people occupied the nine vehicles. Three of the 13 were juveniles.
A traffic detour was put in place, but has since been removed.
Two minor injuries were reported.
54 year old Theresa Selman of Ishpeming was driving westbound on US-41 and lost control of her 2001 Honda.
Selman crossed the median and slid into the path of two eastbound vehicles; A 2013 Toyota Highlander driven by 74 year old Eleanor Weaver of Republic and a 2002 Buick Century driven by 22 year old Kelly Illikainen of Negaunee.
During the collisions, several vehicles lost control while trying to avoid the crash of the first three vehicles, and the other vehicles crashed into either another vehicle, a guardrail, or a ditch.
An ambulance from Marquette General Hospital was also involved in the crash; It was driving by the area at the time and stopped to help, and was hit by a 2004 Chevy Impala driven by 19 year old Casey Juntila of Champion, while she tried to avoid the already crashed cars on the Highway.
Theresa Selman was determined at fault for the crash, and was issued a citation for driving too fast for conditions.
The Michigan State Police is urging motorists to drive safe after numerous crashes occurred on US-41 between Negaunee and Marquette on Monday.
Police say that black ice is causing hazardous road conditions, and drivers should take that into account when traveling throughout Upper Michigan.
