Until
1995 inMontana near the Idaho border, I-90 was not a divided highway for a few stretches, having only a narrow paved median. From1995 until1999 , the speed limit in Montana was "reasonable and prudent"; it is now 75 mph (120 km/h). On the I-90, at Exit 00 (right on the MT/ID border) is the Lookout Pass Ski Area, one exit east of there is the Hiawatha Trail (rails-to-trails).Exit list
