I-90 Closed at St. Regis Due to a Haz Mat Spill from a Semi Truck
The Montana Highway Patrol reported a semi crash early this morning on Interstate 90 on the Montana side near St. Regis.
Trooper Trevor Karsh provided brief details of the incident.
“We were dispatched to a semi rollover,” said Trooper Karsh. “We arrived to find a semi that had crashed into the median barrier and tipped over on to its side, and it has spilled close to 55,000 pounds of talc powder.”
Talc is a clay mineral composed of hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2.
Karsh said both east and westbound lanes of traffic on I-90 are closed as officials are awaiting cleanup crews to arrive, as of 5:00 a.m.
Karsh said there were no injuries in the rollover, however, I-90 is currently closed at St. Regis.
