MHP reporting seven vehicles including two commercial motor vehicles, three passenger vehicles and two wreckers were involved in a multiple vehicle crash. Six people were transported by ambulance to Missoula hospitals with serious injuries. 

A westbound commercial vehicle was traveling too fast for conditions and collided with the dividing concrete barrier causing it to travel into the eastbound lanes where it collided with the other vehicles.

The two wreckers that were hit were already at this location and stopped to help at another crash.

Traffic is now flowing slowly in both directions. I-90 is expected to be completely open within the hour.    

 The accidents happened on Interstate 90 near milepost 144, nine miles west of Drummond.
