A Fond du Lac lawmaker is asking residents to write to a federal judge to express their concerns about a Highway 23 expansion project. The project to widen 23 to four lanes between Fond du Lac and Plymouth was halted a couple years ago when an environmental group filed a lawsuit arguing the expansion wasn’t necessary. A federal judge has yet to make a final ruling. Fond du Lac state representative Jeremy Thiesfeldt told a recent gathering that he is hoping a final order will come down sometime this summer. Thiesfeldt says if there is a favorable ruling he is working to make sure there is funding for the project.
