Westbound traffic diverted to eastbound lanes on I-90 after landslide


MISSOULA, Mont. - A large landslide that shut down part of Interstate 90 near Lookout Pass late Sunday afternoon caused traffic headaches into Monday.

As of Monday afternoon, Montana Department of Transportation officials said westbound traffic will be diverted to eastbound lanes for the time being. There will be two-way traffic in the eastbound lanes with flaggers and pilot cars, so expect delays.

It is possible the westbound lanes will remain closed for the rest of the week.  Our reporter told us the slope is very unstable.

The landslide happened 6.5 miles east of the Idaho state line.

For most of Sunday night into Monday morning, traffic had been diverted at St. Regis to Highway 135 to Highway 200 westbound into Idaho.

Officials were conducting geotechnical assessments to determine the safety of the area.
