Montana officials have closed the westbound lanes of Interstate 90 from St. Regis to the Idaho state line because of the threat of an avalanche.
Ed Toavs of the Montana Department of Transportation tells the Missoulian six small avalanches covered portions of I-90 on Monday. Crews cleared those slides, but Toavs says there are more cracks in the snow on the mountainsides above the roadway.
Westbound drivers are being diverted at St. Regis.
Amtrak spokesman Marc Magliari says the railroad is busing passengers in Spokane, Wash., Whitefish and Shelby to avoid an avalanche that blocked the BNSF Railway tracks near Glacier National Park Sunday.
BNSF spokesman Matt Jones says a maintenance crew spotted around 7 feet of debris on the tracks 10 miles east of Essex at about 11:30 p.m.
