Illinois Route 47 (IL 47) is a largely rural north–south state highway that runs from the Wisconsin state border at Highway 120 near Hebron, to IL 10, just south of Interstate 72 (I-72) near Seymour.

Widenings started occurring further north as early as 2009. A project to reconstruct the road to 4 lanes from Kreutzer Road to Reed Road through Huntley was completed in October 2011, including completing all ramps at the I-90 interchange. IL 47 was widened from I-80 in Morris to Caton Farm Road south of Yorkville as part of the Prairie Parkway study–work was completed in 2015. In 2015, the project to expand the section between IL 71 and Kennedy Road in Yorkville to 4-lanes was completed. The partial interchange with I-88 between Sugar Grove and Elburn was made full with the completion of the missing ramps (using electronic toll collection) in 2019.

Future

The Illinois Department of Transportation is proposing to add lanes to several portions of Illinois Route 47, which eventually would make it a 4-lane road from I-80 in Morris to I-88 in Sugar Grove, and from I-90 in Huntley to north of Woodstock.
