(first report)

The Montana Highway Patrol reports a hazardous spill that has closed a section of I-90 near St. Regis is talcum powder.

MHP Sgt. Sean Finley tells MTN News that a semi-truck from Montana was traveling west on Interstate 90 near mile marker 26 around a curve, when the load on the trailer shifted.

The trailer then flipped, spilling large bags of talcum powder onto the eastbound lanes of I-90 with at least two inches of talcum powder spilling onto the highway.

Sgt. Finley says that it’s considered hazardous when the talcum powder is airborne and a person breathes it in.

A clean up crew arrived on the scene shortly after 10a.m. with vacuums to cleanup up the spill. As of 11 a.m., both eastbound lanes of I-90 were closed, while one westbound lane is open.

MHP is investigating if speed was a factor in the accident. The driver was not hurt, but will be cited for the crash, according to Sgt. Finley.
