The Fox-Wisconsin Heritage Parkway: Portage Canal
Portage Canal: Wikipedia
The Portage Canal was built to connect the Fox River and Wisconsin River at Portage, Wisconsin along the Fox-Wisconsin Waterway. For a time, it completed a route from the north Atlantic Ocean, through the St. Lawrence Seaway and down the Mississippi River to the Gulf of Mexico, and back to the Atlantic.
The Portage Canal is listed on the National Register of Historic Places: Wisconsin.
