The Merrimac Ferry, which crosses the Wisconsin River between Sauk and Columbia counties, is Wisconsin’s only free ferry. It shuttles State Highway 113 traffic between Okee on the east bank and Merrimac on the west. Ferry service has been provided in this area for more than a century. In 1844, four years before Wisconsin became a state, Chester Mattson, the second settler on the site of the village of Merrimac, obtained charters to provide ferry service at this location. The ferry was operated long before the development of a regular roadway.
