 A new detour begins today for drivers traveling along State Highway 23 in central Minnesota. MnDOT is closing the highway to through traffic between Malacca and Bach for a project to resurface the roadway and replace culverts. The posted detour on county roads will be in place through mid-September. The highway will remain open to local traffic. As that detour starts, another has ended. A resurfaced Highway 23 is now back open to traffic between Bach and Ogilvy.
