Eastbound I-94 is once again open after a hazardous material accident blocked traffic in Jackson County for nearly 12 hours.
Police say a trailer caught on fire at about 8:45 a.m. Saturday while passing through Leoni Township.
Traffic in both directions was directed off the interstate while crews let the trailer burn itself out.
Westbound traffic resumed at about 3 p.m.; eastbound lanes were reopened at about 8 p.m.
Those on the scene said fire crews didn't try to extinguish the fire for one simple reason: it contained five pounds of the hazardous compound methyllium.
"Because if it's exposed to the air it's going to ignite possibly explode and if it's exposed to water it has the same potential. To ignite on fire or to react dangerously," said Brian Thurston of the Jackson City Fire Department.
No one was hurt in the fire, and the cause is still under investigation.
The truck had been heading to a chemistry lab at the University of Michigan at the time of the fire.
