EMMETT TOWNSHIP, Mich. (WOOD) — Three semi trucks crashed and spilled hazardous material Thursday afternoon, shutting down a section of the freeway near Battle Creek, troopers say.

According to the Michigan State Police, troopers were sent to eastbound I-94 near 11 Mile Road around 3 p.m.

Responding troopers learned that a semi was traveling in the left lane and rear-ended a truck. The truck was then pushed into a trailer that was being pulled by another semi.

Two of the drivers were taken to the hospital. MSP said their injuries are not considered life-threatening.

Speed is believed to be a factor, MSP said.

On Thursday, the eastbound lanes of the freeway were closed due to the crash and an 800-gallon chemical spill. On Friday, MSP said the chemical was identified as Voramer MR 1165 Isocyanate. The road reopened around 12:20 a.m. Friday.

MSP said the spill “does not pose any short or long term threats to the public or environment.”

The crash remains under investigation.
