Mindoro Cut is a cut in the Town of Farmington in La Crosse County, Wisconsin, which carries Wisconsin Highway 108 through Phillips Ridge, linking Mindoro with West Salem. The cut is 74 feet (23 m) deep, 86 feet (26 m) long, and 25 feet (7.6 m) wide; it is the second-deepest cut built by hand in the Western Hemisphere and the oldest functional cut which has not been improved upon. Work on the cut began in 1907 and concluded in 1908; the project was completed primarily with hand tools.
