Just east of Exit 69, Interstate 90 begins to climb Lookout Pass. This is a long, steep climb which lasts until the Montana border. As you can see from this photo, this stretch of I-90 was undergoing major construction at the time.  (Photo taken 5/25/16).

View on Interstate 90 East climbing Lookout Pass. This single-lane "cattle chute" lasts for the entirety of this construction zone, which lasts the rest of the way through Idaho.  (Photo taken 5/25/16).

Another view on Interstate 90 East proceeding up the grade. With jersey barriers lining the eastbound lane like this, there are absolutely no emergency turnouts on the way up Lookout Pass during this construction. My question is, what if a truck overheats while climbing this long steep grade? Where are they going to go? They will be blocking the entire eastbound side of the road with absolutely no way for traffic behind them to get around. This sounds dangerous and risky to me.  (Photo taken 5/25/16).

Another view on Interstate 90 East. One can only imagine how long it took them to set up these jersey barriers for this construction zone.  (Photo taken 5/25/16).

Another view on Interstate 90 East climbing Lookout Pass. See what I meant about there being no emergency turnouts in the case of a truck overheating?  (Photo taken 5/25/16).

Or maybe not even just a truck overheating, but how about an automobile breaking down or getting a flat tire? Where are they supposed to go?  How would any tow truck or roadside service vehicle get to them? Would you feel comfortable changing your flat in this cattle chute?  (Photo taken 5/25/16).
