Hi Meagan,

Are you sure this segment of 56 is untolled? Signage seems to indicate that Galena Boulevard is the last exit before it becomes a toll road [1]. It appears that there's no way to travel on the part between Galena Boulevard and the I-88 merge without having to go through a toll booth somewhere.
