Multiple vehicles were involved in a series of pileup crashes along Interstate 75 near McNichols Road in Metro Detroit on Monday. The Michigan State Police, which is investigating, said at least a dozen vehicles were involved.

"Fortunately, there are no reported injuries," they added.

The Michigan Department of Transportation said the northbound lanes were shut down along that section of the freeway in Wayne County, starting at about noon, or roughly the same time that snow squalls spun up in Metro Detroit, resulting in whiteout conditions in some places.

Part of the delay, troopers said, was involved with getting vehicles that were stuck amid the crash scenes and the emergency detour turned around and on other routes.

In an update released Monday afternoon, MSP reports that troopers identified 25 separate crashes involving 59 cars and semi-trucks. MSP says several cars left the scene without a crash report. The freeway was closed but has since reopened.

There were also other crashes in the metro area during the day.
