Wyssoneau County was created in 1895. Its county seat was in Brannonsburg from 1895 to 1903, when it was moved to Hoarder Corner. The county has served as a "farming county" for many years. When Dragoonasag Interstate Route 92's routing in the county was being planned in the early 1960s, some farmers were concerned about the freeway cutting through their properties, as the original route was to cut through farmer George Halpos's farm. In 1964, route planners decided to reroute the road so that it would not slice through farms; thus, the current routing of DI-92 in Wyssoneau County.
