Southern terminus on US 151

WIS 113 starts at an intersection with US Highway 151 in Madison. It runs northward as a divided highway through the northeast side of Madison and around the northern shore of Lake Mendota before crossing the Yahara River and exiting the city. East of the village of Waunakee, the highway turns westward and runs concurrently along WIS 19 for about two miles (3.2 km) into the village. In the center of the village, WIS 113 turns northward and separates from WIS 19. From there, it turns westward to pass through the village of Dane and turns northward crossing out of Dane County into Columbia County on the way to Lodi.

In Lodi, the highway intersects WIS 60. WIS 113 continues north-northwesterly through the Town of Westport along the shore of Lake Wisconsin. Across the lake from Merrimac, the highway meets the northern end of WIS 188 and turns north into the parking area for the Merrimac Ferry. WIS 113 uses the ferry to cross Lake Wisconsin and into Sauk County.

Immediately north of the ferry crossing, WIS 113 turns westward and runs concurrently with WIS 78 through Merrimac. West of the village, WIS 113 turns northward. The highway crosses the Baraboo River and turns westerly into the city of Baraboo. After passing the Circus World Museum, WIS 113 turns northward.
