I suspect you took Route 72 or Higgins Road. It runs pretty much the same direction, and you could easily have gotten back on at Route 25 (where Santa's Village is). A good part of it is now under construction, however. In fact, in true Illinois fashion, almost every major road that travels in the same general direction in the area of I-90 is under construction, as is a good part of I-90 itself. Of course, if you are not coming until after November 15 or so, you would be coming in winter as opposed to construction and it might be better. Personally, I would prefer I-90 except at the very height of rush hour because the other choices now have stop lights about every two blocks, and travel through very congested areas.
