Milwaukee’s history is full of grit, ambition, and—believe it or not—bridge sabotage. In 1845, what should have been a simple matter of urban planning turned into an all-out brawl between rival settlements on either side of the Milwaukee River.

His refusal to align Kilbourntown’s streets with neighboring Juneautown was just the beginning. When the Wisconsin Territorial Legislature ordered bridges built to improve travel and trade, Kilbourn saw them as a direct threat to his dominance—and he fought back.
