The highway begins at an intersection with WIS 35 east of Lake Winneshiek, a lake along the Mississippi River. From there, it runs eastward, following Copper Creek until it ends just west of Mount Sterling, where it intersects WIS 27. The highway then runs eastward before curving to the north to run along an unnamed creek, which the highway follows to the southeast until it drains into the Kickapoo River, at which point the highway crosses it to run along Main Street in Gays Mills.
