That's Chicago expressways for you! Although, ever since gas got "expensive" (i.e., last year, but still has it's lasting effects to this day) it seems that less people have been in such a hurry. Or, maybe it's because I haven't had to travel on those roads daily for 3 years

I'd say heating up at 85 mph is normal..that's pretty quick! Granted, the higher rpms will flow more coolant, but pushing a 126 with 121 hp at 85 is still going to be somewhat demanding on the engine.
