Mindoro Cut
Mindoro Cut is a road cut through dolomite rock along State Highway 108 in Wisconsin, carved by hand and dynamite through a steep ridge that once blocked the route. The passage is deep enough for a standard road to pass through, with vertical rock walls rising close on both sides of the lane.
The cut was dug between 1907 and 1908 by hand laborers using basic tools and dynamite, opening a passage that connected Mindoro to nearby towns such as West Salem. The work was completed just as the early automobile era was beginning to change travel across rural Wisconsin.
The cut takes its name from the small town of Mindoro nearby, and locals still regard it as a symbol of what a community can accomplish with determination and physical labor. Driving through it today, the rock walls rise close on both sides, giving a clear sense of how much stone was removed by hand.
The site sits directly along State Highway 108 and is easy to reach by car, with space to pull over and view the rock walls up close from the roadside. Dry weather makes the stone surfaces easier to see, so clear days are a good time to stop.
Mindoro Cut is considered the second deepest hand-dug rock cut in the western half of the United States, a detail that puts the scale of human labor into perspective. During the digging, workers carried loads in wheelbarrows balanced on narrow planks stretched over the sloping sides, which made every load a careful exercise in balance.
