North of West Salem, ride the impressive Mindoro Cut, "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. The
Mindoro Cut was added to the National Register of Historic Places in 2007." More of the Wikipedia article.

“Some of the most beautiful waterscapes and bluff-top views along the Mississippi River can be found in Wisconsin. The Great River Road follows the Mississippi River through 33 river towns. Along the way, travelers will discover the fascinating history and culture of these riverside communities.”
"The Great River Road is a 3,000 mile historic, scenic byway running through 10 states along the Mississippi River. The Great River Road offers a gateway to the river valley’s great history and a host of recreational options to all who journey it.
Wisconsin is home to 250 miles of the Great River Road, of which 22 miles is along State Hwy. 35 on the western edge of Vernon County. Vernon County’s section of the Great River Road runs from near the City of LaCrosse in the north, and southward to the Village of DeSoto.”

Duluth Aerial Lift Bridge spans the Duluth Ship Canal. "Originally built in 1905, the bridge was upgraded in 1929–30 to a vertical lift bridge, which is rather uncommon, and continues to operate today...The bridge can be raised to its full height in about 3 minutes, and goes up 25 to 30 times daily during busy parts of the shipping season. The span is about 390 feet (120 meters)." http://en.wikipedia.org/wiki/Aerial_Lift_Bridge
