Coeur d"Alene, ID to Butte, MT on I-90

Been over it two times in the last two years - some nice grades but I passed a few trucks going up hill even pulling our Jeep

Never had a problem in all my travels on Interstate highways that's the way they were engineered with a max grade of 7%

Came over it this year in the 50 ft long lash-up we have. It was tighter (width) then in past years, due to the construction. But certainly doable.

Traveled that route both directions within the past six weeks. Some construction on Look Out Pass but nothing unusual for normal summer time highway construction and maintenance.

Went through there a couple weeks ago, same direction as you. No problem.

Thanks for the replies.

Since we aren't in a hurry we decided to get off the interstates for a distance and drive up RT 95 to Sandpoint, ID and catch RT 200 east to RT 93 in MT and then drop down to I-90 into Missouli, MT. It looks like a nice two lane road along side of the Clark Fork river for a long way.

My wife and I just traveled that route to Sandpoint from Missoula yesterday. We have a 25' class C towing a Subaru Crosstrek. For the most part, it is an easy scenic drive. There are a couple of relatively short winding stretches where the road narrows due to the proximity of cliffs along the river. It is advisable to follow the speed restrictions in these sections.
