Illinois Roads - I-55

Since I-55 is just an upgraded US 66 all the way across Illinois, it makes sense that the old alignment is never far away. I-55 NB curves west around Williamsville while Oak St. continues straight on old US 66. As a bonus, there's an original alignment of US 66 just to the east along Elm St.
