IL 57 begins at a partial cloverleaf interchange with
I-172, where it heads generally northwest for several miles, passing the communities of
Bluff Hall and
Marblehead. After an intersection with 24th Street, IL 57 curves slightly north, where it turns into Gardner Expressway, passing numerous industries and small businesses, before passing a large underground storage complex. The highway becomes highly industrialized, turning into a four-lane divided expressway for over a mile. The highway turns slightly to the east at Jefferson Street, taking on the 3rd Street designation, and straightens out. Once inside Quincy proper, IL 57 becomes a four-lane arterial for a third of a mile before splitting into two legs. The northbound leg follows York Street eastward for one block, turns north onto 4th Street, and terminates at US 24 just two blocks later, while the southbound leg starts at IL 104/US 24 and follows 3rd Street. IL 57 is an undivided, rural two-lane road for most of its length. == History ==
