UPDATE: 15 cars involved in U.S. 31 pile-up
BERRIEN SPRINGS, Mich. -- The U.S. 31 bypass is back open after a 17 car pile-up.
The multiple car crash happened just after 8:30 a.m. Michigan State police shut down the northbound lanes.
Troopers said the pile-up had police scrambling to clean up what is described as a huge mess.
Kevin Greenwood, a passing driver, contacted us on Facebook and said there was "steel coil in the median, a cryogenic tanker on the right shoulder, and several cars are stopped."
We were told that two semis were also involved.
Officers say a car slowed down in the heavy fog, causing a chain reaction crash.
Amazingly, only was person was hurt and is expected to be okay.
It took several hours to clean up the scene so traffic could resume.
