context_section_description: Illinois 163 begins at a junction with Illinois 158 in downtown Millstadt. The highway leaves the village to the north, entering rural Millstadt Township. After passing St. James Catholic Cemetery, it crosses into Stookey Township. The route then curves north-northwest past Concordia Church and Cemetery. Upon crossing Prairie Dupont Creek, it turns north through the community of Westview. At Booker T. Washington Cemetery, the route heads northwest into Centreville Township, where it meets Illinois 157. The highways run northward concurrently and enter Centreville before intersecting Illinois 13. At this junction, Illinois 157 follows Illinois 13 eastward, while Illinois 163 continues northward through a primarily residential area. The highway turns northeast into Alorton and passes under an overpass carrying Interstate 255 and U.S. Route 50, which do not meet Illinois 163.  From here Illinois 163 runs parallel to the south of Illinois 15 before terminating at an intersection with this route. Illinois 163 is a two-lane road for its entire length.
