Annually, during the periods that MnDOT officially imposes seasonal road restrictions, county highways, township roads, and City streets not paved with concrete are restricted to five-ton axle posting, unless signs indicate otherwise. Throughout the year, any public roadway may be restricted to less than normal weights, as indicated by signs posted that limit axle and axle group weights.
