The Colsac III Ferry
The Colsac III ferry operates from mid-April to November 30, each year, weather permitting and operates 24/7 in season. "Colsac" is a phonetic combination of the names of Columbia and Sauk Counties, separated by the Wisconsin River. A ferry has been in operation at this site since 1844, four years before Wisconsin became a state.
The Wisconsin DOT site claims this is a one-mile crossing, but near as I can tell, it's really about 4/10 of a mile.

The current vessel (COLSAC III) was dedicated on May 16, 2003. The previous steel vessel (COLSAC II) was put into service in 1963, and ran for 40 years. The original wooden COLSAC was already in service in 1933 when the State of Wisconsin took over operation of this service. No information is available for the vessels that preceded this COLSAC.
