no. Once you around Galena it goes to 2 lane all the course to Freeport. They were working on making it 4 lane in spots along the means of access but I dont know how far they got.
It vary. I haven't driven it in a while, but I remember portions of US 20 between Galena and Rockford going down to 2 lane, one in respectively direction, for good portions.
